气候变化下的新疆生态环境脆弱性评价

选取了脆弱性、适应能力作为影响新疆生态环境脆弱性的条件层，进一步筛选出海拔、地质环境、沙尘暴、人口密度、降水量、植被类型、生态保护政策7个因子作为成因指标层，并用专家打分法对每个指标赋予权重。将研究区剖分成195个评价单元格，借助G玛强大的数据管理功能，建立与空间数据和属性数据相互关联的生态环境脆弱性数据库；首次采用模糊数学层次分析法作为新疆生态环境脆弱性等级计算的数学模型，计算出新疆生态环境脆弱性等级，并借助CIS进行成果表达。

The Assessment of Ecosystem Vulnerability to Climate Change of Xinjiang

The vulnerability and adaptahility were selected as the conditional layer of ecostem vulnerability factors of xinjiang. The altitude, geological environment sanddust storms, population density, precipitation, vegetation, environment protecting policy were selected as the reason index layer. Each index power was given usirlg the expert mark method. The study area was partitioned to 195 cell griddings for assessment. Tho ecosystem vulnerability database associated with space - data and attrihute- data was established using the great data management function of GIS, The fuzzy mathematics layer analyse method was used as the math model to calculate xinjiang ecosystem vulnerability for the fast time. The ecosystem vulnerability grade was calculated and expressed from GIS.
