| 中文摘要: |
| 在参考已有研究成果基础上，以PSR（压力-状态-响应）模型为依据，建立威宁草海湿地生态安全评价指标体系（包括17个指标），同时，采用模糊数学法建立评价模型，以均方差法确定各个评价指标权重，对威宁草海湿地的生态安全进行实例评价。结果显示，压力要素和响应要素处于不安全等级；状态要素处于极不安全等级；威宁草海湿地生态安全对应“安全、较安全、较不安全、不安全、极不安全5个安全级别的隶属度值分别为0.0626、0.1197、0.2141、0.3312、0.2724”，处于不安全的隶属度值最大（0.3312），根据模糊数学最大隶属度原理，威宁草海湿地生态安全处于不安全等级，湿地生态安全有待改善。通过评价，掌握了威宁草海湿地生态安全状况，以期为威宁草海湿地规划建设提供参考依据。 |
| 英文摘要: |
| The evaluation index(including 17 indicators) system of ecological security was established. By the existing research results with PSR (pressure state response) model as the basis in Weining Caohai wetland. At the same time, fuzzy mathematics was utilized to establish the evaluation model,and Mean square error method was employed to give indexes weight. Then the situation of ecological security in Weining Caohai wetland was study as a case. The results indicated that the pressure factor aspect and response elements aspect of ecological security in Weining Caohai wetland were graded unsafe, state factors aspect was graded extremely insecure. The ecological security of Weining Caohai wetland value for membership: 0.0626、0.1197、0.2141、0.3312、0.2724, the ecological security in unsafe level, wetland ecological security needs to be improved. Through the evaluation, grasp the Caohai wetland ecological security in Weining, to provide reference for the planning and construction of Weining Lake wetland. |
