模糊物元分析在岩溶生态安全评价中的应用——以重庆市11区县为例

Application of Fuzzy Matter Element Analysis in Karst Ecological Security Assessment—A Case Study of 11 Counties in Chongqing

运用模糊物元模型理论,采用P-S-R生态评价模型构建了岩溶生态环境安全评价指标体系。选取相关数据对重庆市三峡库区11个区县的岩溶生态环境安全进行评价。结果表明,研究地11区县岩溶生态环境安全度从大到小依次为垫江县(0.485 6)、梁平县(0.373 9)、丰都县(0.365 6)、忠县(0.330 2)、万州区(0.303 1)、开县(0.301 6)、奉节县(0.272 4)、巫山县(0.248 8)、云阳县(0.240 5)、城口县(0.158 2)、巫溪县(0.122 8)。通过引入模糊物元模型的分析方法,为决策部门制订相应的政策及岩溶生态环境安全评价提供有益借鉴。

Using fuzzy matter element analysis, P-S-R ecological evaluation model was used to construct the index system of Karst ecological environment safety evaluation. The relevant data were adopted to evaluate Karst ecological environment in 11 counties in the Three Gorges Reservoir Region in Chongqing. The results showed that the safety degree of Karst ecological environment in 11 counties from good to bad was in the order as Dianjiang County （0. 485 6 ） 〉 Liangping County （0. 373 9 ） 〉 Fengdu County （ 0. 365 6 ） 〉 Zhong County （0. 330 2 ） 〉 Wanzhou District （ 0. 303 1 ） 〉 Kai County （0. 301 6） 〉 Fengjie County （0. 272 4） 〉 Wushan County （0.248 8 ） 〉 Yunyang County （ 0.240 5 ） 〉 Chengkou County （0. 158 2 ） 〉 Wuxi County （0. 122 8 ）. The introduction of fuzzy matter element model provides useful reference for decision-making departments to formulate corresponding policies to evaluate regional environment and safety of Karst ecological environment.
