基于AHP法的山东省生态脆弱性综合评价

从影响山东省生态脆弱性的主要因素出发,建立生态潜在脆弱性-人为干扰脆弱性的评价指标体系。在运用层次分析法定权的基础上,将综合指数法和GIS相结合形成生态脆弱性的综合评价方法。根据生态脆弱分级标准,将山东省17个地市的生态脆弱性分成4类,即轻度、中度、强度、极强度脆弱。评价结果显示,山东省强度脆弱区共有5个市,占全省总面积的17.1%,多层次的评价分析对于各地区有针对性采取措施降低生态脆弱性具有重要的理论意义。

Comprehensive Evaluation of Shandong Ecological Vulnerability Based on AHP Method

Ecological vulnerability evaluation index system of potential vulnerability-human disturbance was established starting from main influ- encing factors of Shandong Province. On the basis of AHP weight determining,comprehensive index method and GIS were ebmbined to form the comprehensive evaluation method of ecological vulnerability. According to the value of ecological fragility and grade standard of ecological fragili- ty, 17 cities in Shandong Province were divided into four categories, namely slightly vulnerable, moderate vulnerable, intensively vulnerable and extremely intensity vulnerable. The results showed that there were a total of 5 counties with high ecological vulnerability, accounting for 17.1% of the total area of the province. Multilevel evaluation analysis has important theoretical significance for various areas adopting measures to reduce the ecological vulnerabilitv.
