2Impact of livelihood diversification of rural households on their ecological footprint in agro-pastoral areas of northern China显示文摘Human-environment relationship is a focus of academic researches and an understanding of the relationship is important for making effective policies and decisions. In this study, based on rural household survey data of Taibus Banner, Duolun county and Zhengxiangbai Banner in the Inner Mongolia autonomous region of China, we identified the impact of livelihood diversification on ecosystems in these agro-pastoral areas by using the ecological footprint theory and methodology together with the one-way analysis of variance(ANOVA) and correlation analysis methods. In 2011, the total ecological footprint of consumption(EFC) was 0.665 g hm2, and the total ecological footprint of production(EFP) was 2.045 g hm2, which was more than three times the EFC. The ecological footprint of arable land consumption(EFAC) accounted for a large proportion of the EFC, and the ecological footprint of grassland production(EFGP) occupied a large proportion of the EFP. Both the ecological footprint of grassland consumption(EFGC) and EFGP had a significant positive correlation with the income, indicating that income was mainly depended on livestock production and the households with higher incomes consumed more livestock products. The full-time farming households(FTFHs) had the highest EFP, ecological footprint of arable land production(EFAP), EFGP and EFGC, followed by the part-time farming households(PTFHs) and non-farming households(NFHs), which indicated that part-time farming and non-farming employment reduced the occupancy and consumption of rural households on local ecosystems and natural resources to some extent. When farming households engaged in livestock rearing, both the EFAP and EFAC became smaller, while the EFP, EFC, EFGC and EFGP increased significantly. The differences in ecological footprints among different household groups should be taken into account when making ecosystem conservation policies. Encouraging the laborers who have the advantages of participating in non-farming employment to move out of the rural areas and increasing the diversification of livelihoods of rural households are important in reducing the environmental pressures and improving the welfare of households in the study area. Moreover, grassland should be utilized more effectively in the future.HAO Haiguang ZHANG Jiping LI Xiubin ZHANG Huiyuan ZHANG Qiang 2015Journal of Arid Land2015,7,5:19
3Strengthening shale wellbore with silica nanoparticles drilling fluid显示文摘Nanoparticles have been widely used to reduce wellbore instability problems of shale formation.In this paper,nanoparticle-containing water-based drilling fluids(WBDFs)and oil-based drilling fluids(OBDFs)were evaluated by running three new tests including spontaneous imbibition,swelling rate and acoustic transit time.Results showed that,for the WBDFs,nanoparticles leaded to higher plastic viscosity(PV)and yield point(YP),and lower API-filtration.Moreover,because pore throats of shale can be plugged by nanoparticles,imbibition amount,swelling rate,and Young's-modulus reduction of shale decreased significantly.Higher concentration of nanoparticles can induce better plugging effect.However,for the OBDFs,nanoparticles did not show these positive effects like the nano WBDFs,even leaded to some negative effects such as higher filtration and larger Young'smodulus reduction.The main reasons are that the silica nanoparticles can easily disperse in the WBDFs,and effectively prevent the filtrate invading into shale by plugging pore throats.But the same silica nanoparticles are difficult to disperse in OBDFs,and do not perform the expected functions.This study indicates that nano WBDFs have great potential to reduce the wellbore instability problems of shale formation.Yili Kang Jiping She Hao Zhang Lijun You Minggu Song 2016Petroleum2016,2,2:7

5Monitoring gas-and particulate-phase short-chain polychlorinated paraffins in the urban air of Dalian by a self-developed passive sampler显示文摘The concentration of short-chain polychlorinated paraffins(SCCPs) in the urban air of Dalian,China was monitored from September 2016 to August 2017 with a self-developed passive sampler(PAS1) and an active high-volume sampler, simultaneously. PAS1 successfully collected the entire target SCCPs in the ambient air. Air SCCPs sampled by PAS1 were found be in the linear uptake stage during 181 days of sampling. Passive and active samples showed comparable congener profiles, and the dominant contributors of SCCPs in the two kinds of samples were similar. A significant linear correlation was observed between the total concentration of SCCPs sampled by PAS1 and active sampler in the four seasons. The passive sampling rates of the PAS1 for the gas and particulate phases of SCCPs were measured. The quantitative structure–property relationship of the sampling rate of PAS1(Rair) for gas-phase SCCPs was studied. From the molecular point of view, Rairwas mainly affected by the molecular weight and sub-cooled liquid vapor pressure of SCCPs. In general, SCCPs in the urban air of Dalian mainly existed in gas phase,lower molecular weight SCCPs primarily occurred in the gas phase, whereas higher molecular weight SCCPs were predominately adsorbed or absorbed on airborne particles. The air concentration of SCCPs in the four seasons were different, the correlation of the concentration of SCCPs in the air with the meteorology parameters was conducted. The exposure risk by intake air SCCPs of the residents around the sampling sites was evaluated according to the European risk assessment standards.Yifan Wang Xiuhua Zhu Yuan Gao Hao Bai Pengyuan Wang Jiping Chen Heping Yuan Longxing Wang Xiaoxiao Li Wei Wang 2019Journal of Environmental Sciences2019,31,6:2

8A facile design for multifunctional AIEgen based on tetraaniline derivatives显示文摘Aniline oligomers have been widely used in many fields due to their excellent physicochemical properties. Owing to strong intermolecular interactions, their emission is always weakened or quenched when they are in high concentration or aggregated state, which greatly limits their fluorescent applications. Inspired by the concept of aggregation-induced emission(AIE), herein we introduced large steric groups onto the aniline oligomer to prevent the formation of packing structure. In particular, diphenyl vinyl group was bonded with oligomeric tetraaniline by a facile synthetic procedure with high yield. The obtained aniline oligomer derivative exhibited typical AIE features, which was also confirmed by density functional theoretical calculation. More importantly, this AIE oligomer was able to detect Fe^(3+) ions selectively and quantitatively. The fluorescence intensity decreased linearly along with the increment of Fe^(3+) concentration. Moreover, we demonstrated that this AIE oligomer could stain live bacteria, such as E. coli and S. aureus efficiently. All these results suggest that such a readily accessible and multifunctional tetraaniline derivative provides a new platform for the construction of fluorescent materials.Beibei Liu Wei He Hao Lu Kun Wang Mingming Huang Ryan Tsz Kin Kwok Jacky Wing Yip Lam Longcheng Gao Jiping Yang Benzhong Tang 2019Science China Chemistry2019,62,6:1

12An Unprecedented Record Low Antarctic Sea-ice Extent during Austral Summer 2022显示文摘Seasonal minimum Antarctic sea ice extent(SIE)in 2022 hit a new record low since recordkeeping began in 1978 of 1.9 million km^(2) on 25 February,0.17 million km^(2) lower than the previous record low set in 2017.Significant negative anomalies in the Bellingshausen/Amundsen Seas,the Weddell Sea,and the western Indian Ocean sector led to the new record minimum.The sea ice budget analysis presented here shows that thermodynamic processes dominate sea ice loss in summer through enhanced poleward heat transport and albedo-temperature feedback.In spring,both dynamic and thermodynamic processes contribute to negative sea ice anomalies.Specifically,dynamic ice loss dominates in the Amundsen Sea as evidenced by sea ice thickness(SIT)change,while positive surface heat fluxes contribute most to sea ice melt in the Weddell Sea.Jinfei WANG Hao LUO Qinghua YANG Jiping LIU Lejiang YU Qian SHI Bo HAN 2022Advances in Atmospheric Sciences2022,39,10:1

14Carbon storage of a subtropical forest ecosystem: a case study of the Jinggang Mountain National Nature Reserve in south-eastern China显示文摘The carbon cycle of forest ecosystems plays a key role in regulating CO2 concentrations in the atmosphere. Research on carbon storage estimation of forest ecosystems has become a major research topic. However, carbon budgets of subtropical forest ecosystems have received little attention. Reports of soil carbon storage and topographic heterogeneity of carbon storage are limited. This study focused on the Jinggang Mountain National Nature Reserve as an example of a mid-subtropical forest and evaluated soil and vegetation carbon storage by field sampling combined with GIS, RS and GPS technology. We classified the forest into nine forest types using ALOS high-resolution remote sensing images. The evergreen broad-leaved forest has the largest area, occupying 26.5% of the total area, followed by coniferous and broad-leaved mixed forests and warm temperate coniferous forest, occupying 24.2 and 22.9%, respectively. The vegetation and soil carbon storage of the whole forest ecosystem were 1,692,344 and 5,514,707 t, with a carbon density of 7.4 and 24.2 kg/m^2, respectively, which suggests that the ecosystem has great carbon storage capacity. The topographic heterogeneity of the carbon storage was also analysed. The largest vegetation storage and soil storage is at 700–800 and 1000–1100 m, respectively. The vegetation carbon storage is highest in the southeast, south and southwest.Jiping Zhang Linbo Zhang Haiguang Hao Chunlan Liu Hui Wang 2019Journal of Forestry Research2019,30,3:1

18Driving factors and the implications of work choices of rural laborers in ecologically vulnerable areas in North China显示文摘Using rural survey data for the year 2009,we provide evidence of work choices of rural laborers in ecologically vulnerable areas in North China,and model these choices as a function of characteristics of individuals,households,and land endowments.The findings reveal large differences between males and females,and between non-farm employment and part-time farming engagement Land scarcity is still an important driving factor in non-farming participation of rural laborers in the study area;and in the current case of land productivity and the total amount of land,there are still surplus rural labor forces in the study area.Diversification of livelihood reduces the pressure on land,thus facilitating ecosystem conservation.So,the paper concludes with the argument that establishing coordination mechanisms among non-farm employment of rural laborers,agricultural production,and restoration of ecosystems are essential for mitigating the conflicts of ecological security,agricultural production,and rural development in mis area.Haiguang Hao Xiubin Li Huiyuan Zhang Jiping Zhang 2013Chinese Journal of Population,Resources and Environment2013,11,4:0

20Characterization of the Flexural Behavior of Bamboo Beams显示文摘Bamboo is a renewable and environmentally friendly material often used for construction.This study investigates the flexural behavior of bamboo beams through theoretical and finite element(FE)analyses.Considering the material’s nonlinearity,a method of calculating load-deflection curves is proposed and validated via FE analysis.The interfacial slippage dominated by the shear stiffness of the interface between two bamboo poles significantly influences the flexural behavior of double-pole bamboo beams.Thus,the load-deflection curves for different shear stiffnesses can be obtained via theoretical and FE analyses.Subsequently,a novel configuration using diagonal steel bands to avoid slippage is presented.An inclination angle of 45°is suggested to adequately develop the stiffness and bearing capacity of the steel band.Limin Tian Jianpeng Wei Jiping Hao Qiushuo Wang 2021Journal of Renewable Materials2021,9,9:0
