| 1 | Model of water-sediment regulation in Yellow River and its effect显示文摘Water-sediment regulation of the Yellow River is to regulate and control the flow and sediment transport relationship of the lower reaches through reservoirs on the main streams and tributaries to create balance between water and sediment so that sediment transport capacity of the downstream channels can be maximized,shrinking of channels be contained,and medium flood channel be restored and maintained.Many years' research by the Yellow River Conservancy Commission(YRCC) reveals the water and sediment transport relationship that will prevent sedimentation at the downstream river channels.Based on this relationship and coming sediment and water conditions in the Yellow River basin,the YRCC,with maximized use of reservoirs on the main streams and tributaries,has developed three models of water-sediment regulation:single Xiaolangdi Reservoir-dominated regulation,space scale water-sediment match,and mainstream reservoirs joint operation.Ten water-sediment regulations based on these three models have resulted in an average drop of 1.5 m in the main channel of the downstream 800 km river and an increase of carrying capacity from 1800 to 4000 m3/s.Besides,the wetland ecosystems of estuarine delta has also been improved and restored significantly. | LI GuoYing SHENG LianXi | 2011 | Science China(Technological Sciences)2011，54，4： | 18 |
| 2 | Cullin-RING Ubiquitin Ligase Family in Plant Abiotic Stress Pathways显示文摘The ubiquitin-proteasome system is a key mechanism that plants use to generate adaptive responses in coping with various en- vironmental stresses. Cullin-RING (CRL) complexes represent a predominant group of ubiquitin E3 ligases in this system. In this review, we focus on the CRL E3s that have been implicated in abiotic stress signaling pathways in Arabidopsis. By comparing and analyzing these cases, we hope to gain a better understanding on how CRL complexes work under various settings in an attempt to decipher the clues about the regulatory mechanism of CRL E3s. | Liquan Guo Cynthia D.Nezames Lianxi Sheng Xingwang Deng Ning Wei | 2013 | Journal of Integrative Plant Biology2013，55，1： | 9 |
| 3 | Effect of grain refinement induced by wire and arc additive manufacture (WAAM) on the corrosion behaviors of AZ31 magnesium alloy in NaCl solution显示文摘Additive manufacturing(AM)of Mg alloys has become a promising strategy for producing complex structures,but the corrosion performance of AM Mg components remains unexploited.In this study,wire and arc additive manufacturing(WAAM)was employed to produce single AZ31 layer.The results revealed that the WAAM AZ31 was characterized by significant grain refinement with non-textured crystallographic orientation,similar phase composition and stabilized corrosion performance comparing to the cast AZ31.These varied corrosion behaviors were principally ascribed to the size of grain,where cast AZ31 and WAAM AZ31 were featured by micro galvanic corrosion and intergranular corrosion,respectively. | Jianwei LI Youmin QIU Junjie YANG Yinying SHENG Yanliang YI Xun ZENG Lianxi CHEN Fengliang YIN Jiangzhou SU Tiejun ZHANG Xin TONG Bin GUO | 2023 | Journal of Magnesium and Alloys2023，11，1： | 6 |
| 4 | Measurement and Scaling of Mercury on Soil and Air in a Historical Artisanal Gold Mining Area in Northeastern China显示文摘The Jiapigou gold mine area, located in the upper reaches of the Songhua River, was the first and largest artisanal gold mine once in China, and it used to be prominent in two marking years(1870 and 1974). Jiapigou area had a gold mining history of more than 190 years, which was first opened in 1820. Gold extraction with algamation was applied as the dominant method of excavation from 1940 to 2008, and a total of more than 100 t of gold were extracted from the mine using this method and it was estimated that 100–200 t Hg were released, thus causing severe mercury environmental pollution in the mining area. In the experimental campaigns of this study, in situ air and soil Hg concentrations and air-soil Hg fluxes were measured from April 2009 to December 2011. The results showed that in the study area the total gaseous mercury(TGM) concentration exhibited remarkable spatial and temporal distribution patterns, i.e. the TGM gradually decreased following the increase in distance to gold mining sites in space, and the values in spring, summer and autumn were elevated by 1–2 orders of magnitude in comparison with those in winter. Furthermore, at other sampling sites the total soil mercury(TSM) concentration in spring was higher than that in autumn, except for the contrary laws demonstrated at the Erdaogou mining site. However, in spring and winter the Hg flux between air and soil was under the control of different environmental factors, and the characteristics were clear and distinct. In spring the Hg flux between air and soil was directly under the control of solar irradiation, and the releasing process was predominant with a remarkable positive correlation to solar irradiation. Nevertheless, in winter the Hg fluxes were indirectly under the control of solar irradiation, which caused thermal inversion due to the thick snow cover. The depositing process was predominant and the correlations between Hg flux and air temperature was remarkably negative, and there was a positive correlation between Hg flux and solar irradiation. | WANG Zhaojun ZHANG Gang CHEN Xiaobing ZHAO Qiaojing WANG Weiying SHENG Lianxi BIAN Hongfeng LI Zhenxin WANG Deli | 2019 | Chinese Geographical Science2019，29，2： | 3 |
| 5 | Impact of Wetland Change on Local Climate in Semi-arid Zone of Northeast China显示文摘Wetlands are sensitive to climate change, in the same time, wetlands can influence climate. This study analyzed the spatio-temporal characteristics of wetland change in the semi-arid zone of Northeast China from 1985 to 2010, and investigated the impact of large area of wetland change on local climate. Results showed that the total area of wetlands was on a rise in the study area. Although natural wetlands(marshes, riparians and lakes) decreased, constructed wetlands(rice fields) increased significantly, and the highest increase rate in many places exceeded 30%. Anthropogenic activities are major driving factors for wetland change. Wetland change produced an impact on local climate, mainly on maximum temperature and precipitation during the period of May–September. The increase(or decrease) of wetland area could reduce(or increase) the increment of maximum temperature and the decrement of precipitation. The changes in both maximum temperature and precipitation corresponded with wetland change in spatial distribution. Wetland change played a more important role in moderating local climate compared to the contribution of woodland and grassland changes in the study area. Cold-humid effect of wetlands was main way to moderating local climate as well as alleviating climatic warming and drying in the study area, and heterogeneity of underlying surface broadened the cold-humid effect of wetlands. | LIU Yan SHENG Lianxi LIU Jiping | 2015 | Chinese Geographical Science2015，25，3： | 3 |
| 6 | Foraging areas of Rousettus leschenaulti on the Hainan Island of China显示文摘We investigated the foraging area of three individuals (1 female and 2 males) of Rousettus leschenaulti (Chiroptera,Pteropodidae) in suburban Haikou City, Hainan Province, South China from November 2005 to January 2006 using radio telemetry.These animals left the daytime roosting sites about 90 min after sunset with no significant difference in departure time betweenthe male and female bats. The average active times were 391.8 min for males and 533.7 min for the female, respectively.By reconstructing 93 radio-telemetry recording positions, we found that the long axis of foraging area of the bats ranged from7.45 to 11.70 km. The foraging area of the female (3867 ha) was larger than that of the males (1138 ha), and there was overlapbetween the foraging areas of different individuals. These bats usually kept the same flight routes across a few successive daysfrom the daytime roosting site to the foraging areas. Our findings suggested that female R. leschenaulti may explore a larger foragingarea than males. No obvious territorial behaviors were observed in our studied area. | Zhanhui TANG Zhong CHEN Jie MA Guangjian ZHU Xunfeng MA Lianxi SHENG Yuchun LI | 2010 | Current Zoology2010，56，4： | 2 |
| 7 | Echolocation calls of Myotis frater (Chiroptera: Hipposi- deridae) during search flight显示文摘Echolocation calls of Myotis frater emitted during the search phase consist of brief frequency-modulated pulses. The sound signals are comprised of three harmonics of which the first one is of the highest intensity and occurs in all echolocation calls. The frequency of this fundamental harmonic ranges from 110.8 to 50.2 kHz, and its duration is about 3.5 ms. The second and the third harmonics are relatively weak, occurring in 50.0% and 25.0% of echolocation calls respectively, with frequencies ranging from 138.4 to 116.6 kHz for the second harmonic and from 193.6 to 170.8 kHz for the third harmonic. We presume that, according to the echolocation call features, Myotis frater probably forages the insects on the ground of complex environments. | ZHANG Shuyi ZHAO Huihua FENG Jiang SHENG Lianxi LI Zhenxin WANG Lixin | 2000 | Chinese Science Bulletin2000，45，18： | 2 |

| 11 | Relationship between echolocation frequency and body size in two species of hipposiderid bats显示文摘Frequencies of echolocation calls with maximum power of Himalayan leaf-nosed bats and Horsfield’s leaf-nosed bats during searching phase were 74.1 and 92.1 kHz, respectively. Head-body length, forearm length and body mass of Himalayan leaf-nosed bats were 82.9 mm, 89.7 mm and 59.1 g, respectively; and the corresponding values of Horsfield’s leaf-nosed bats were 68.4 mm, 61.3 mm and 19.7 g, respectively. Echolocation frequency and the three parameters of body size, head-body length, forearm length and body mass, were all negatively correlated, and the correlation coefficients were -0.86, -1.58 and -2.19, respectively. This study thereby proved that echolocation frequency and body size were negatively correlated in the two species of hipposiderid bats. | ZHANG Shuyi ZHAO Huihua FENG Jiang SHENG Lianxi WANG Hui WANG Lixin | 2000 | Chinese Science Bulletin2000，45，17： | 1 |

| 13 | Measurement of light polarization characteristics from an oil-polluted soil surface in near-infrared bands显示文摘Oil pollution can be monitored by infrared remote sensing technology. In this work, the degree of po-larization (DOP) was established as a quantitative index of oil pollution. The crude oil and the local typical surface soil from the Songyuan oil field in Jilin province were collected. Some soil samples with four levels of oil content and three levels of water content were prepared and measured. The DOP of the polluted soil and the clean soil in the field was also measured at 180° relative viewing azimuth angle, and 10°, 30° and 50° viewing zenith angles. It was found that with rising soil oil content, the DOP of the reflected light on the soil surface increased when the soil water content was low, and decreased when the soil water content was high. | WANG Yuan SHENG LianXi LI Ke ZHAO NaiZhuo ZHAO YunSheng | 2009 | Chinese Science Bulletin2009，54，9： | 1 |

| 16 | Distribution and Accumulation of Soil Carbon in Temperate Wetland, Northeast China显示文摘Estimating carbon sequestration and nutrient accumulation rates in Northeast China are important to assess wetlands function as carbon sink buffering greenhouse gas increasing in North Asia. The objectives of this study were to estimate accreting rates of carbon and nutrients in typical temperate wetlands. Results indicated that average soil organic carbon(SOC), total nitrogen(TN) and total phosphorus(TP) contents were 37.81%, 1.59% and 0.08% in peatlands, 5.33%, 0.25% and 0.05% in marshes, 2.92%, 0.27% and 0.10% in marshy meadows, respectively. Chronologies reconstructed by 210 Pb in the present work were acceptable and reliable, and the average time to yield 0–40 cm depth sediment cores was 150 years. Average carbon sequestration rate(Carbonsq), nitrogen and phosphorus accumulation rates were 219.4 g C/(m^2·yr), 9.16 g N/(m^2·yr) and 0.46 g P/(m^2·yr) for peatland; 57.13 g C/(m^2·yr), 5.42 g N/(m^2·yr) and 2.16 g P/(m^2·yr) for marshy meadow; 78.35 g C/(m^2·yr), 8.70 g N/(m^2·yr) and 0.71 g P/(m2·yr) for marshy; respectively. Positive relations existed between Carbonsq with nitrogen and precipitations, indicating that Carbonsq might be strengthened in future climate scenarios. | LYU Mingzhi SHENG Lianxi ZHANG Zhongsheng ZHANG Li | 2016 | Chinese Geographical Science2016，26，3： | 1 |

| 18 | Mapping Deciduous Broad-leaved Forested Swamps Using ALOS/Palsar Data显示文摘Accurate, updated information on the distribution of wetlands is essential for estimating net fluxes of greenhouse gases and for effectively protecting and managing wetlands. Because of their complex community structure and rich surface vegetation, deciduous broad-leaved forested swamps are considered to be one of the most difficult types of wetland to classify. In this research, with the support of remote sensing and geographic information system, multi-temporal radar images L-Palsar were used initially to extract the forest hydrological layer and phenology phase change layer as two variables through image analysis. Second, based on the environmental characteristics of forested swamps, three decision tree classifiers derived from the two variables were constructed to explore effective methods to identify deciduous broad-leaved forested swamps. Third, this study focused on analyzing the classification process between flat-forests, which are the most severely disturbed elements, and forested swamps. Finally, the application of the decision tree model will be discussed. The results showed that: 1) L-HH band(a L band with wavelength of 0–235 m in HH polarization mode; HH means Synthetic Aperture Radars transmit pulses in horizontal polarization and receive in horizontal polarization) in the leaf-off season is shown to be capable of detecting hydrologic conditions beneath the forest; 2) the accuracy of the classification(forested swamp and forest plat) was 81.5% based on hydrologic features, and 83.5% was achieved by combining hydrologic features and phenology response features, which indicated that hydrological characteristics under the forest played a key role. The HHOJ(refers to the band created by the subtraction with HH band in October and HH band in July) achieved by multi-temporal radar images did improve the classification accuracy, but not significantly, and more leaf-off radar images may be more efficient than multi-seasonal radar images for inland forested swamp mapping; 3) the lower separability between forested swamps dominated by vegetated surfaces and forest plat covered with litter was the main cause of the uncertainty in classification, which led to misleading interpretations of the pixel-based classification. Finally, through the analysis with kappa coefficients, it was shown that the value of the intersection point was an ideal choice for the variable. | BIAN Hongfeng YAN Tingting ZHANG Zhengxiang HE Chunguang SHENG Lianxi | 2016 | Chinese Geographical Science2016，26，3： | 0 |
| 19 | Growth and Carbon Metabolism Responses to Flooding Timing and Frequency in Three Marsh Plants in Sanjiang Plain显示文摘Flooding timing and frequency may have different effects on the growth and carbon metabolism of plants in wetlands. We tested this hypothesis using three marsh plants in Sanjiang Plain, which were growing in different flooding timing and frequency environments for 24 days. The three marsh plants in different elevations along a water-level gradient, high-elevation species Calamagrostis angustifolia, mid-elevation species Carex limosa and low-elevation species Carex lasiocarpa. Our experiment included 6 kinds of treatments: control, longer flooding timing, medial flooding timing and frequency(2 treatments), and higher flooding frequency(2 treatments). Longer flooding timing and higher flooding frequency treatments led to similar reductions in biomass accumulation and relative growth rate of Calamagrostis angustifolia, whereas growth of Carex limosa was not affected by either flooding timing or frequency. However, biomass accumulation and relative growth rate of Carex lasiocarpa was only reduced by the higher flooding frequency. Starch and soluble sugar contents of Calamagrostis angustifolia were negatively affected by flooding frequency. On Carex limosa, higher flooding frequency resulted in higher starch content, but longer flooding timing led to accumulated starch content in Carex lasiocarpa. Soluble sugar contents of Carex lasiocarpa and Carex li mosa were not affected by either flooding timing or flooding frequency. These results indicated that growth responses of the three marsh plants to flooding timing and frequency was closely related to the different physiology of carbohydrate metabolism. | LIU Zinan WANG Xue LUO Wenbo SHENG Lianxi | 2014 | 湿地科学2014，12，1： | 0 |
