- 摘要:
- 生态脆弱性评价可为生态脆弱流域生态经济系统的恢复与重建提供重要的依据。在分析影响该流域生态脆弱性因素的基础上，从成因和表现结果两个方面构建了佳芦河流域生态脆弱性评价指标体系，并将人口素质等人文信息纳入生态脆弱性指标体系。利用集对分析方法对佳芦河流域生态脆弱性进行了评价，结果表明：当i=0时，联系度μ（A，BⅠ）最大为0.5，说明该流域的生态脆弱性处于高度脆弱状态；当i=（a-c）/（a+c）时，无论a、c取何值，μ（A，BⅡ）恒为1，采用级间比较进行评价，因为μ（A，BⅠ）比μ（A，BⅢ）更为接近μ（A，BⅡ），表明佳芦河流域生态处于Ⅰ～Ⅱ之间，该流域生态处于比较高的脆弱状态。集对分析法以联系度为核心，在处理不确定性问题时，具有计算方便、方法简单，评判结果客观、合理等特点，为流域生态脆弱性综合评价提供了一种新的途径。
- Abstract:
- An important basis is provided ecological vulnerability assessment for ecologically fragile watershed ecosystem economic systems restoration and reconstruction.Based on an analysis of the Impact factors on the ecological vulnerability in the basin,an ecological fragility assement index system is built to consider the causes and the results of manifestations in JiaLu river basin,and the quality of the population and other cultural information is contained in the index system of ecological fragility.The set pair analysis method is utilized to evaluate the ecological vulnerability in contrast to the first method in JiaLu River basin.The results show that: when i=0,μ（A，BⅠ) of the largest connection degree is equal to 0.5,indicating the ecological vulnerability of the basin is highly vulnerable state; when i=(a-c)/(a+c),whether a,c take what the value,μ（A，BⅡ) as a constant,using inter-stage evaluation of comparison,the value of μ（A，BⅠ) than the μ（A，BⅢ) closer to μ（A，BⅡ),the ecological vulnerability that is in between Ⅰ~Ⅱ in JiaLu River Basin,at a relatively high vulnerability state.The Set Pair analysis is an calculation convenient method with simpleness and judge the results of objective,rational characteristics to compare with the first method,a new way is provided for a comprehensive assessment of watershed ecological vulnerability.
