| 1 | Mapping wetland changes in China between 1978 and 2008显示文摘Four wetland maps for all China have been produced,based on Landsat and CBERS-02B remote sensing data between 1978 and 2008 (1978,1990,2000 and 2008).These maps were mainly developed by manual interpretation and validated by substantial field investigation in 2009.Based on these maps,we analyzed the 2008 wetland distribution in China and discussed wetland changes and their drivers over the past 30 years.(i) There were about 324097 km 2 of wetlands in 2008,for which inland marshes or swamps were the most common wetland type (35%),with lakes (26%) second.Most of the wetlands were in Heilongjiang,Inner Mongolia,Qinghai and Tibet,occupying about 55% of the national wetland area.(ii) From 1978 to 2008,China's wetland area continually and significantly decreased,by about 33% based on changes in the wetland map.This was in sharp contrast to the increase in artificial wetlands,which increased by about 122%.Inland marshes accounted for the main loss of total wetlands from 1978 to 2000.From 2000 through 2008,riverine and lacustrine wetlands constituted the main wetland loss.Fortunately however,the rate of wetland loss decreased from 5523 to 831 km 2 /a.(iii) The change ratio of lost natural wetlands (including inland and coastal wetlands) to non-wetlands has decreased slightly over the past 30 years.From 1978 to 1990,nearly all natural wetlands (98%) lost were transformed into non-wetlands.However,the ratio declined to 86% from 1990 to 2000,and to 77% from 2000 to 2008.(iv) All Chinese provinces were divided into three groups according to patterns of wetland changes,which could relate to the driving forces of such changes.Tibet was completely different from other provinces,as it was one representative example in which there was a net wetland increase,because of global warming and decreased human activity since 1990.Increased economic development caused considerable wetland loss in most eastern provinces,and artificial wetlands increased. | NIU ZhenGuo ZHANG HaiYing WANG XianWei YAO WenBo ZHOU DeMin ZHAO KuiYi ZHAO Hui LI NaNa HUANG HuaBing LI CongCong YANG Jun LIU CaiXia LIU Shuang WANG Lin LI Zhan YANG ZhenZhong QIAO Fei ZHENG YaoMin CHEN YanLei SHENG YongWei GAO XiaoHong ZHU WeiHong WANG WenQing WANG Hong WENG YongLing ZHUANG DaFang LIU JiYuan LUO ZhiCai CHENG Xiao GUO ZiQi GONG Peng | 2012 | Chinese Science Bulletin2012,57,22: | 51 |
| 2 | Geographical characteristics of China’s wetlands derived from remotely sensed data显示文摘In this paper, we report the first wetland mapping of the entire China using Landsat enhanced thematic mapper plus (ETM+) data. These data were obtained from the Global Land Cover Facility at the University of Maryland spanning from 1999 to 2002. A total of 597 scenes of Landsat images were georeferenced and mosaiced. Manual image interpretation of satellite images was aided with elevation data, soil data, land cover/land use data and Google Earth. The minimum mapping unit is 10 pixel × 10 pixel, equivalent to 9 ha. The aim of our first round of mapping was only targeted at the boundary delineation of any type of wetland except those wetlands that are under agricultural use (i.e., paddy fields), which has already been well mapped by others. Our interpretation results indicate that a total of 359478 km2 of wetlands are of non-agricultural use. Among our preliminarily mapped wetland, 339353 km2 are inland wetland, 2786 km2 are non-agricultural artificial wetland, and 17609 km2 are coastal wetland. Because low-tide is rarely captured in satellite images, an under-estimation of coastal wetland is inevitable. We conducted some statistics based on our mapped wetlands and compared them with those previously obtained from a number of sources including a land cover/land use map made with satellite images during the late 1990s and early 2000s, a marshland map developed in approximately the same period, survey data of coastal wetland in early 1980s, and area data for approximately 400 larger patches of marshland in China compiled in 1996. Because some inconsistencies exist in the guidelines of those different wetland surveys, difference in area is expected. Some further comparison indicates that the wetland distributions derived from the preliminary wetland map are reasonable and more objective than other sources. The mapping process also indicated that the method adopted by us was efficient and cost-effective. We also found that in order to ensure comparability of the wetland maps developed at different times, a set of standard guidelines on the wetland categories to be mapped, and the mapping methods to be used must be well conceived, developed and effectively employed. We carried out some initial geographical analysis on the distribution of wetlands. | NIU ZhenGuo GONG Peng CHENG Xiao GUO JianHong WANG Lin HUANG HuaBing SHEN ShaoQing WU YunZhao WANG XiaoFeng WANG XianWei YING Qing LIANG Lu ZHANG LiNa WANG Lei YAO Qian YANG ZhenZhong GUO ZiQi DAI YongJiu | 2009 | Science China Earth Sciences2009,52,6: | 15 |
| 3 | An improved Landsat Image Mosaic of Antarctica显示文摘A revised Landsat Image Mosaic of Antarctica (LIMA) is presented, using the 1073 multi-band scenes of the original Landsat-7 ETM+ LIMA image collection available at the United States Geological Survey (USGS: http://gffzza64998f73d704ee0h0xnvq5fwnvwn6ncf.ffgz.tsg.suse.edu.cn/). Three improvements have been applied during the data processing: (1) DN saturation is adjusted by adopting a linear regression, which has a lower root mean square error than the ratio regression used by LIMA; (2) solar elevation angle is calculated using pixel-level latitude/longitude and the acquisition time and date of the central pixel of the scene, improving slightly upon the bilinear interpolation of the solar elevation angles of scene corners applied in LIMA; and (3) two additional image bands, Band 5 and Band 7, are sharpened using the panchromatic band (Band 8) and a Gram-Schmidt Spectral Sharpening algorithm to more easily distinguish snow, cloud and exposed rocks. The final planetary reflectance product is stored in 16-bit bands to preserve the full radiometric content of the scenes. A comparative statistical analysis among 12 sample regions indicates that the new mosaic has enhanced visual qualities, information entropy, and information content for land cover classification relative to LIMA. | HUI FengMing CHENG Xiao LIU Yan ZHANG YanMei YE YuFang WANG XianWei LI Zhan WANG Kun ZHAN ZhiFei GUO JianHong HUANG HuaBing LI XiuHong GUO ZiQi GONG Peng | 2013 | Science China Earth Sciences2013,56,1: | 4 |
| 4 | Cooperative Differential Game for Model Energy-Bandwidth Efficiency Tradeoff in the Internet of Things显示文摘Internet of Things(IoT) refers to an infrastructure which enables the forms of communication and collaboration between people and things,and between things themselves.In order to improve its performance,we present a tradeoff between bandwidth and energy consumption in the IoT in this paper.A service providing model is built to find the relationship between bandwidth and energy consumption using a cooperative differential game model.The game solution is gotten in the condition of grand coalition,feedback Nash equilibrium and intermediate coalitions and an allocation policy is obtain by Shapley theory.The results are shown as follows.Firstly,the performance of IoT decreases with the increasing of bandwidth cost or with the decreasing of energy cost;secondly,all the nodes in the IoT composing a grand coalition can save bandwidth and energy consumption;thirdly,when the factors of bandwidth cost and energy cost are equal,the obtained number of provided services is an optimised value which is the trade-off between energy and bandwidth consumption. | LIN Fuhong LIU Qian ZHOU Xianwei CHEN Yueyun HUANG Daochao | 2014 | China Communications2014,11,1: | 3 |
| 5 | Positive influence of the scattering medium on reflective ghost imaging显示文摘The scattering medium is usually thought to have a negative effect on the imaging process.In this paper,it is shown that the imaging quality of reflective ghost imaging(GI)in the scattering medium can be improved effectively when the binary method is used.By the experimental and the numerical results,it is proved that the existence of the scattering medium is just the cause of this phenomenon,i.e.,the scattering medium has a positive effect on the imaging quality of reflective GI.During this process,the effect from the scattering medium behaves as the random noise which makes the imaging quality of binary ghost imaging have an obvious improvement. | QIN FU YANFENG BAI XIANWEI HUANG SUQIN NAN PEIYI XIE XIQUAN FU | 2019 | Photonics Research2019,7,12: | 3 |

| 8 | Influences of Lateral Double-Layered Deflectors on Cooling Performance of Air-Cooled Condenser显示文摘The cooling performance of air-cooled condenser(ACC)is susceptible to adverse impacts of ambient winds.In this work,three kinds of lateral double-layered deflectors installed under the ACC platform are proposed to weaken the unfavorable effects of cross winds.Through CFD simulation methods,the main parameters of thermo-flow performances of a 2×660 MW direct dry cooling system are obtained,by which it can be concluded that the deflectors can effectively reduce the inlet air temperatures while enhance the mass flow rates of upwind fans due to the guiding effect,especially at high wind speeds,while the improvement of cooling capacity of ACCs in the 0°wind direction is weak.The inclined-vertical deflectors are superior to others in performance improvement of ACCs for all cases,which can reduce the turbine back pressure by 12.15%when the wind speed is 12 m/s,so they can be applied to the performance enhancement of ACCs under windy conditions in practical engineering. | HUANG Wenhui HUANG Xianwei YANG Lijun DU Xiaoze | 2021 | Journal of Thermal Science2021,30,6: | 1 |

| 17 | Fabrication of microwave-sensitized nanospheres of covalent organic framework with apatinib for tumor therapy显示文摘A new nanocomposite of hollow covalent organic framework(COF)conjugated with the apatinib(AP)and loading microwave-sensitizer(ionic liquid,IL)was prepared by layer by layer(LBL)method and hyaluronic acid(HA)coating,named as COF-AP-IL@HA.AP loading rate in COF hollow-spheres(~30 nm shell thickness)was~40.3%,due to the interactions of hydrogen andπ-πbonds between AP and COF shell,and acidic environment destroyed COF structure,promoting AP release.Microwave sensitization of loaded IL in COF hollow-spheres could enhance the microwave heat-effect,and combined AP therapeutic ability,leading to their higher inhibitation on tumor,due to targeting ability of HA and the local release of apatinib.88.9%of inhibition rate of COF-AP-IL@HA under microwave on the in vivo tumor was significantly higher than those without microwave(12.3%)and COF-IL@HA with microwave(37.5%),indicating a synergism of sensitized microwave hyperthermia and AP therapy on the reduced expression of VEGF via the downregulation pathway of hypoxia inducible factor.These results indicated that COF-AP-IL@HA was potential to the application in the combination therapy of tumor of the sensitized microwave hyperthermia and apatinib. | Qijun Du Jian Zou Zhongbing Huang Shimei Li Longfei Tan Xiangling Ren Guangfu Yin Yongfa Zheng Xianwei Meng | 2023 | Chinese Chemical Letters2023,34,5: | 0 |
| 18 | Telomere-to-telomere genome of the allotetraploid legume Sesbania cannabina reveals transposon-driven subgenome divergence and mechanisms of alkaline stress tolerance显示文摘Alkaline soils pose an increasing problem for agriculture worldwide,but using stress-tolerant plants as green manure can improve marginal land.Here,we show that the legume Sesbania cannabina is very tolerant to alkaline conditions and,when used as a green manure,substantially improves alkaline soil.To understand genome evolution and the mechanisms of stress tolerance in this allotetraploid legume,we generated the first telomere-to-telomere genome assembly of S.cannabina spanning~2,087 Mb.The assembly included all centromeric regions,which contain centromeric satellite repeats,and complete chromosome ends with telomeric characteristics.Further genome analysis distinguished A and B subgenomes,which diverged approximately 7.9 million years ago.Comparative genomic analysis revealed that the chromosome homoeologs underwent large-scale inversion events(>10 Mb)and a significant,transposon-driven size expansion of the chromosome 5A homoeolog.We further identified four specific alkali-induced phosphate transporter genes in S.cannabina;these may function in alkali tolerance by relieving the deficiency in available phosphorus in alkaline soil.Our work highlights the significance of S.cannabina as a green tool to improve marginal lands and sheds light on subgenome evolution and adaptation to alkaline soils. | Haofei Luo Xiaofei Wang Changqing You Xuedan Wu Duofeng Pan Zhiyao Lv Tong Li Dongmei Zhang Zhongbao Shen Xiaodong Zhang Guodao Liu Kaixuan He Qingtong Ye Yajun Jia Qinghua Zhao Xian Deng Xiaofeng Cao Xianwei Song Gai Huang | 2024 | Science China(Life Sciences)2024,67,1: | 0 |
| 19 | Nanoscale metal organic frameworks inhibition of pyruvate kinase of M2显示文摘Tumor cells usually show abnormally high glycolysis rate to maintain the dynamic balance of energy.The growth of tumor cells can be affected by inhibiting the activity of pyruvate kinase(especially M2-type isozyme,PKM2),the rate limiting enzyme of glycolysis.This is helpful to the treatment of tumor.Herein,metal organic frameworks(MOFs) were found to inhibit the activity of PKM2.Nanoscale ZIF-8 was synthesized by standing and ultrasonic method,respectively.The ZIF-8 has the performance of inhibiting PKM2.Further research showed that the inhibition ability was attributed to zinc ion in ZIF-8.Interestingly,the IC_(50) of ZIF-8 on PKM2 was one percent of that of zinc ion.This novel enzyme inhibitor is expected to be used in cancer therapy. | Xiangling Ren Xinyuan Huang Qiong Wu Longfei Tan Changhui Fu Yi Chen Xianwei Meng | 2021 | Chinese Chemical Letters2021,32,10: | 0 |
| 20 | Zirconium metal-organic framework nanocrystal as microwave sensitizer for enhancement of tumor therapy显示文摘Although surgical resection and chemotherapy were widely applied in tumor therapy, the dysfunction of normal cells resulted in the side effects (such as anorexia, nausea). MW thermal therapy is a non-invasive anticancer strategy under the help of MW sensitizer, with the safety and higher efficacy. Zirconium metal-organic framework nanocubes (ZrMOF NCs) modified with polyethylene glycol, were prepared via one pot method and carbodiimide technique, resulting in their large specific surface area and porosity.Our results showed that non-ion-loaded ZrMOF NCs in 0.9% NaCl solution exhibited better heating effect,higher than that in pure water, due to the robust collision among the ions under MW irradiation. The in vivo experiments confirmed that ZrMOF-PEG NCs + MW group exhibited the higher temperature in the tumor region than that of only MW treatment, suggesting a better MW thermal therapeutic anticancer efficacy. This work provides a new preparation strategy of biosafety nanomaterial as MW sensitizer for enhancing MW thermal anticancer therapy. | Yuanwen Zou Wei Zhang Hongqiao Zhou Changhui Fu Longfei Tan Zhongbing Huang Xiangling Ren Jun Ren Xudong Chen Xianwei Meng | 2019 | Chinese Chemical Letters2019,30,2: | 0 |
