摘　　要：湿地生态环境质量评价需要考虑评价指标的属性,从湿地生态、湿地功能、湿地环境等3个方面建立评价指标体系,把熵权理论和模糊物元进行融合,构建了基于熵权的模糊物元模型方法,并运用该方法对2012年威宁草海湿地的生态环境质量进行评价。结果表明,2012年威宁草海湿地生态环境质量处于"中"的水平。制约因子主要有水质状况、水质净化功能、侵蚀控制功能和生物栖息地功能等。通过评价,了解了威宁草海湿地生态环境的质量状况,为有关部门的科学管理和规划提供了参考。The attribute evaluation index should be considered in the Assessment of wetland eco-environmental quality.In this study,the evaluation index system is established from three aspects of wetland,wetland function,wetland environment.The entropy theory and fuzzy matter-element are fused to construct the fuzzy matter element model based on entropy weight.The ecological environment quality of Weining Caohai wetland in the year of 2012 is evaluated by using this method.The results show that the ecological environment quality is at the middle level;the restriction factors include water quality,water purification,soil erosion control function and wildlife habitat function.Through evaluation,the status of ecological environment quality of Caohai wetland in Weining is understood,which will provide references for scientific management and planning.
