文章摘要：从生态敏感性和生态恢复力两个方面构建测度指标体系,应用GIS的空间分析技术定量测度城市生态环境脆弱性的大小并划分等级分区,进而得到不同的脆弱性调控类型区.以合肥市为例,在GIS平台上具体测度了其生态环境脆弱性的大小,并划分为低、较低、中、较高和高5种脆弱性分区,进而归纳为生态绿线、生态灰线和生态红线3种脆弱性调控类型区.其中,生态绿线调控区的规模最大,占研究区总面积的53.61%,这可以为合肥市提供充足的发展空间.最后给出了不同脆弱性调控类型区的发展建议,由此为城市生态环境的保护和建设提供科学的决策依据.

Abstr：The measurement indicator system was established from two perspectives of ecological sensitivity and ecological resiliency. Meanwhile, the GIS spatial analysis technology was adopted for the quantitative measurement and classification of the urban coo-environmental vulnerability, thus obtaining the type zone of vulnerability control. In Hefei, for example, the eco-environmental vulnerability was specifically measured on GIS platform. Then it was divided into 5 vulnerability zoning, including low, relatively low, middle, relatively high and high and concluded as three type zones of vulnerability control, namely, ecological green line, ecological grey line and ecological red line. Among which, the control zone of ecological green line had the largest scale, taking up 53.61% of the total area and providing sufficient development space for Hefei. At last, suggestions for the development of different type zones of vulnerability control were offered so as to provide scientific decision-making basis for the protection and development of urban eco-environment.
