摘要
旨在确定湿地生态负荷及环境容量,为制定环境区域规划及环境法规等提供科学依据。以国家级自然保护区湖南省东洞庭湖湿地为研究区,利用Mamdani FIS模型,构建了包含水体pH值,水体悬浮物浓度、土壤pH值、土壤含水量、植被类型数量、入侵物种数量、湿地面积变化率、人口密度、产业结构等9个影响因子的指标体系,进行了湿地生态系统健康评价。结果显示:东洞庭湖湿地生态系统健康评价得分为1.37分,健康状态介于亚健康和不健康之间。Mamdani FIS模型的非线性分析能力和基于专家意见的推理规则,提高了评价结果的客观性,对湖泊湿地生态环境保护政策的合理制定具有重要参考价值。
The aims are to determine the ecological load and environmental capacity of wetlands,and provide references for making environmental regional planning and environmental laws.Taking East Dongting Lake as the studying area,the Mamdani FIS (Fuzzy Reasoning System)model was used to construct the index system including nine factors,water pH,the suspended solids concentration in water,soil pH,soil water content,the number of vegetation types,the number of invasive species,the rate of wetland area change,the population density,and the industrial structure.The wetland ecosystem health assessment was carried out.The results showed that the health assessment score of East Dongting Lake wetland ecosystem was 1.37,the status of health was between sub-health and unhealthy.Based on the nonlinear analysis ability of Mamdani FIS model and the reasoning rules using expert opinions,the assessment results of wetland ecosystem health are more objective,and have important reference values for the reasonable formulation of the ecological environment protection policy for lake wetlands.
