Spatial distribution of ecological security status assessment of West-Liaohe River based on geographic information system

Eco-security assessment is a hot research area in resource and environmental science, which involves data with much spatial, non-linear, and random features. Geographic information system (GIS), as a useful tool to analyze and manage spatial information, has a superior advantage in this field. A case study in the western part of the Liaohe River featuring a method of eco-security spatial differences (ESSD) based on GIS is developed in this paper. The method includes four steps: 1) developing the pressure-state-response (P-S-R) framework with site data; 2) digitizing West-Liaohe River and setting its GRID database of ecosecurity assessment indicators; 3) figuring out the relative membership degree (RMD) of eco-security indicators by using the analytical hierarchy process with the weight of indicator; 4) classifying the security zone and mapping the assessment result of eco-security status in grid by GIS method of assigning and clustering. The visual spatial differences of eco-security based on GIS enables decision makers to know the status of eco-security better in making policies for achieving sustainability. __________ Translated from Environmental Science, 2005, 26(5): 28–33 [译自: 环境科学]

古尔班通古特沙漠1970-2000年代生物结皮覆盖变化研究

生物结皮是古尔班通古特沙漠主要的地表覆盖类型,也是维持其地表稳定的重要生物因子。论文利用20世纪70年代中期、80年代末期及21世纪初的遥感影像,通过生物结皮指数提取了古尔班通古特沙漠在相应时期内的生物结皮空间分布。在此基础上,分析了研究区近30年来生物结皮空间分布的变化特征;利用景观分析软件Fragstats计算了各个时期内结皮覆盖的景观指数熏并对其变化特征进行了分析。结果表明:由于新疆气候增湿、增暖明显,近30年来结皮发育良好。但由于油田开采、水利工程建设、牲畜放牧等人类活动的加强,结皮发育受到较为严重的干扰,区域内结皮斑块破碎化程度加大。
