苏州市生态脆弱性评价

摘要
结合苏州市区域概况,选取引起苏州生态环境变化的影响因子,以生态/自然潜在/人为干扰的角度建立苏州市生态脆弱性评价体系。运用层次分析法选取10个判定指标并计算出权重,再运用综合指数法计算区域的脆弱度,分析各个区域的生态质量。最后采用ArcGIS空间分析能力对苏州市各个区域的环境进行整体判定和分析。本文将苏州市分成3层脆弱等级,即轻度脆弱区、中度脆弱区、重度脆弱区。结果表明,常熟市为重度脆弱区,吴江区为轻度脆弱区。结合人为因素和自然因素,本研究对苏州市生态环境质量进行了综合评价。
Based on the regional overview of Suzhou City, the impact factors causing changes in Suzhou's ecological environment were selected to establish an ecological vulnerability assessment system in Suzhou from the perspective of ecological/natural potential/human interference. Using the analytic hierarchy process to select 10 judgment indicators and calculate the weights, and then use the comprehensive index method to calculate the regional vulnerability, and analyze the ecological quality of each region. Finally, the ArcGIS spatial analysis capability is used to make an overall judgment and analysis of the environment in various areas of Suzhou. This paper divides Suzhou into three levels of vulnerability, namely,mildly vulnerable areas, moderately vulnerable areas, and severely vulnerable areas. The results show that Changshu City is a severely vulnerable area, and Wujiang District is a slightly vulnerable area. The ecological environment quality of Suzhou is comprehensively evaluated in combination with human factors and natural factors.
