1DEM栅格分辨率和子流域划分对杏子河流域水文模拟的影响显示文摘以黄土丘陵沟壑区杏子河流域为研究区,采用数字滤波法分割了杏子河招安水文站1958—1974年的基流量,评价了SWAT模型在该流域水文模拟的适用性,并分析了DEM栅格分辨率和子流域划分对SWAT水文模拟的影响。结果表明,SWAT模型适用于该流域年河川径流、地表径流、基流及产沙量的模拟。当DEM栅格分辨率在20—150 m之间时,SWAT能有效地模拟年河川径流、地表径流、基流及产沙量,各水文要素模拟结果的R2和NSE分别在0.93和0.51以上,RSR在0.43以下;而当栅格分辨率大于150 m时,各水文要素的模拟效果存在差异。子流域划分对流域产流模拟影响较小,而对产沙模拟影响较大。当子流域提取阈值在12—100 km2之间时,不同的子流域划分对产沙量几乎没有影响,若超出该阈值范围,模型会低估产沙量。因此,可针对不同的水文要素选择合适的DEM和子流域提取阈值,以提高模拟精度和运行效率。邱临静 郑粉莉 Yin Runsheng 2012生态学报2012,32,12:29
2Mercury isotope variations in surface soils in different contaminated areas in Guizhou Province,China显示文摘Guizhou Province is known as a heavily Hg-polluted area in China due to its special geochemical background and complicated Hg emission sources.In this study,we investigated the Hg isotope compositions of surface soil samples in the Hg mining area,zinc smelting area,coal combustion area,which are known to be the typical pollution regions of Hg in this province.We also compared the Hg isotopic fingerprints of primary Hg sources,such as hydrothermal Hg-bearing ores,coals and atmospheric Hg samples.According to our study,Hg stored in surface soils in different pollution regions in Guizhou Province displays a wide range of both mass dependent fractionation(MDF,δ202Hg) and mass independent fractionation(MIF,△199Hg).δ 202 Hg varies by 2.0‰ and △199Hg varies by 0.25‰ in the investigated surface soils.This study demonstrated that using a 'MDF-MIF' two dimensional Hg isotope system could be particularly useful in discriminating Hg sources in soils.FENG XinBin YIN RunSheng YU Ben DU BuYun 2013Chinese Science Bulletin2013,58,2:13
3Effects of soil properties on production and bioaccumulation of methylmercury in rice paddies at a mercury mining area,China显示文摘Rice paddy soil is recognized as the hotspot of mercury(Hg) methylation, which is mainly a biotic process mediated by many abiotic factors. In this study, effects of key soil properties on the production and bioaccumulation of Hg and methylmercury(MeHg) in Hg-contaminated rice paddies were investigated. Rice and soil samples were collected from the active Hg smelting site and abandoned Hg mining sites(a total of 124 paddy fields) in the Wanshan Mercury Mine, China. Total Hg(THg) and MeHg in soils and rice grains, together with sulfur(S),selenium(Se), organic matter(OM), nitrogen(N), phosphorus(P), mineral compositions(e.g., SiO_2, Al_2O_3 and Fe_2O_3) and pH in soils were quantified. The results showed that long-term Hg mining activities had resulted in THg and MeHg contaminations in soil-rice system. The newly-deposited atmospheric Hg was more readily methylated relative to the native Hg already in soils, which could be responsible for the elevated MeHg levels in soils and rice grains around the active artificial Hg smelting site. The MeHg concentrations in soils and rice grains showed a significantly negative relationship with soil N/Hg, S/Hg and OM/Hg ratio possibly due to the formation of low-bioavailability Hg–S(N)–OM complexes in rhizosphere. The Hg–Se antagonism undoubtedly occurred in soil-rice system, while its role in bioaccumulation of MeHg in the MeHg-contaminated rice paddies was minor. However, other soil properties showed less influence on the production and bioaccumulation of MeHg in rice paddies located at the Wanshan Mercury Mine zone.Deliang Yin Tianrong He Runsheng Yin Lingxia Zeng 2018Journal of Environmental Sciences2018,30,6:8
4High-precision measurement of mercury isotope ratios of atmospheric deposition over the past 150 years recorded in a peat core taken from Hongyuan, Sichuan Province, China显示文摘High-precision 210Pb dating technology was applied to a peat core with a time span of about 150 years that was taken from Hongyuan, Sichuan Province, China. The concentrations of total mercury (Hg) and stable isotope compositions of mercury in the peat core were measured using a LUMEX 915 instrument and multi-collector inductively coupled plasma mass spectrometer, respectively. Total mercury (Hg) concentrations in the peat core had a clearly increasing trend from the bottom to top of the core while δ 202Hg values (relative to NIST 3133) of peat had a decreasing trend. The total mercury (Hg) concentration varied from 16.7 to 101.3 ng/g and the δ 202Hg values ranged from –0.44‰± 0.14‰ to –1.45‰± 0.22‰. We clearly show that the study area experienced mercury pollution after the industrial revolution, and the mercury emitted from natural sources and anthropogenic sources had different Hg isotope signatures.SHI WenFang FENG XinBin ZHANG Gan MING LiLi YIN RunSheng ZHAO ZhiQi WANG Jing 2011Chinese Science Bulletin2011,56,9:7
5退耕还林对经济社会影响评价的研究显示文摘退耕还林推行10年以来,学术界、政界对项目的经济社会影响评价的讨论及争论越来越激烈。本文基于对整个领域研究进展了解,分别从数据、方法及结论等方面对Yao(2010)、Liu(2010)以及Uchita(2009)3篇文献进行简要述评。指出非农就业、农户增收不能单纯通过退耕还林本身实现,而要从思路和技术上跳出仅仅围绕退耕户或者退耕地来讨论项目经济社会影响的局限,并指出了未来可能的研究方向及政策建议。王征兵 郭斌 姚顺波 朱文清 刘璨 Runsheng Yin 2012农业经济与管理2012,,5:7

9Mercury isotope constraints on the genesis of late Mesozoic Sb deposits in South China显示文摘The late Mesozoic antimony(Sb)mineralization belt in South China hosts a large portion of the world’s Sb reserves.However,the source and mineralization processes of these Sb deposits remain controversial.Here,we measured mercury(Hg)concentrations and isotopic compositions of stibnite in the Banpo Sb-only and Woxi Sbpolymetallic ore deposits,as well as associated rocks in the Yangtze Block in order to constrain the metal sources and ore formation processes in the South China Sb mineralization belt.Stibnite samples from both deposits exhibit significant enrichment in Hg(4.23–50.6 ppm)and have higher δ^(202)Hg values(−0.47‰to 2.03‰)than the studied Precambrian basement rocks(−1.42‰to 0.59‰),Paleozoic sedimentary rocks(−2.40‰to−0.32‰),and other natural Hg reserves(e.g.,marine and continental systems).This indicates that significant mass-dependent fractionation of Hg isotopes occurred during hydrothermal processes.Negative to slightly positive Δ^(199)Hg values of−0.17‰to 0.02‰were obtained for stibnite from the studied deposits,similar to values for the Precambrian basement rocks,but different from those of the Paleozoic sedimentary rocks and data previously reported for mantle materials.This suggests that Precambrian basement rocks were the source of Hg and associated metals.Our data and the tectonic evolution of South China indicate that late Mesozoic asthenospheric upwelling,in response to the Paleo-Pacific oceanic slab foundering,generated heat that drove the circulation of fluids in the basement and crustal basinal rocks.These fluids leached Sb,Hg,and other metals from the Precambrian basement rocks and formed the world-class Sb mineralization belt in South China.Changzhou DENG Jiawei ZHANG Ruizhong HU Kai LUO Yanan ZHU Runsheng YIN 2022Science China Earth Sciences2022,65,2:1
