选取我国平原河网典型区域—江苏省内重点湖泊、水库及河流等为研究对象,系统调查江苏省地表水环境沉积物中有机氯农药(OCPs)的残留现状,解析区域空间分布特征和来源并评估其生态风险.结果表明,目标区域湖泊、水库及河流表层沉积物中20种OCPs化合物检出率为100%,残留范围为0.41~10.62ng/g dw(平均值为3.14ng/g dw).与国内其它流域相比,江苏省地表水环境表层沉积物中OCPs的污染负荷整体处于较低水平.OCPs单体化合物特征比值溯源结果显示,江苏省表层沉积物中的OCPs主要来源于历史残留.运用风险熵值法对江苏省表层沉积物OCPs进行生态风险评估,结果显示环氧七氯是主要的生态风险因子,其次为α-硫丹和异狄氏剂.联合生态风险评价表明太湖梅梁湾湖区处于高风险,不同水体类型沉积物OCPs风险水平呈现为湖泊高于河流、河流高于水库的整体趋势.在国家加强新污染物治理的背景下,OCPs等传统持久性有机污染物POPs同样需要持续关注,支撑流域水环境复合污染治理和风险防范.

china is one of the countries where landslides caused the most fatalities in the last decades. The threat that landslide disasters pose to people might even be greater in the future, due to climate change and the increasing urbanization of mountainous areas. A reliable national-scale rainfall induced landslide susceptibility model is therefore of great relevance in order to identify regions more and less prone to landsliding as well as to develop suitable risk mitigating strategies. However, relying on imperfect landslide data is inevitable when modelling landslide susceptibility for such a large research area. The purpose of this study is to investigate the influence of incomplete landslide data on national scale statistical landslide susceptibility modeling for china. In this context, it is aimed to explore the benefit of mixed effects modelling to counterbalance associated bias propagations. Six influencing factors including lithology, slope,soil moisture index, mean annual precipitation, land use and geological environment regions were selected based on an initial exploratory data analysis. Three sets of influencing variables were designed to represent different solutions to deal with spatially incomplete landslide information: Set 1(disregards the presence of incomplete landslide information), Set 2(excludes factors related to the incompleteness of landslide data), Set 3(accounts for factors related to the incompleteness via random effects). The variable sets were then introduced in a generalized additive model(GAM: Set 1 and Set 2) and a generalized additive mixed effect model(GAMM: Set 3) to establish three national-scale statistical landslide susceptibility models: models 1, 2 and 3. The models were evaluated using the area under the receiver operating characteristics curve(AUROC) given by spatially explicit and non-spatial cross-validation. The spatial prediction pattern produced by the models were also investigated. The results show that the landslide inve

chinese deserts and sand fields in Last Glacial Maximum and Holocene Optimum

The Last Glacial Maximum (LGM, c. 26-16 ka) and the Holocene Optimum (HO, c. 9-5 ka) were characterized by cold-dry and warm-wet climates respectively in the recently geological Earth. How chinese deserts and sand fields responded to these distinctive climatic changes is still not clear, however. To reconstruct environments of the deserts and sand fields during the LGM and HO is helpful to understand the forcing mechanisms of environment change in this arid region, and to test paleoclimatic modeling results. Through our long-term field and laboratory investigations, 400 optically stimulated luminescence (OSL) ages and more than 100 depositional records in the chinese deserts and sand fields were obtained; on the basis of these data, we reconstruct spatial distributions of the deserts and sand fields during the LGM and HO. Our results show that the sand fields of Mu Us, Hunshandake, Horqin and Hulun Buir in northern and northeastern china had expanded 25%, 37%, 38% and 270%, respectively, during the LGM; the sand fields of Gonghe in the northeastern Qinghai-Tibetan Plateau had expanded 20%, and the deserts of Badain Jaran, Tengger in central northern china had expanded 39% and 29% separately during the LGM; the deserts of Taklimakan, Gurbantünggüt and Kumtag in northwestern china had expanded 10%-20% respectively, compared to their modern areas. On the other hand, all of the sand fields were nearly completely covered by vegetation during the HO; the deserts in northwestern and central northern china were reduced by around 5%-20% in area during this time. Lakes in this arid region were probably expanded during the HO but this conclusion needs more investigation. Compared with the geological distributions of deserts and sand fields, human activity has clearly changed (expanded) the area of active sand dunes at the present time. Our observations show that environmental conditions of chinese deserts and sand fields are controlled by regional climate together with human a
