摘要
基于湿地生态健康理论,采用层次分析法和德尔菲法,以广西第二次湿地资源调查中75处重点湿地为研究对象,构建了广西重点湿地生态系统健康状况综合评价指标体系,确定了评价指标、权重、评价方法和评价等级。结果表明:广西湿地生态系统健康状况为"好"的湿地占37.3%,湿地生态系统健康状况为"中"的湿地占57.4%,湿地生态系统健康状况为"差"的占5.3%。广西湿地生态系统健康状况总体一般,一些具有重要意义的湿地仍受到不同程度的威胁,主要表现在水质污染、不合理利用等方面,应受到保护管理部门的重视。
Based on the theory of wetland ecosystem health, using the Analytic Hierarchy Process and Delphi method, and the data obtained in the Second Wetland Resources Survey, a health assessment indicators system was developed for the 75 key wetlands in Guangxi province. Indicators and their weights, method and grading of assessment were determined. Results showed that wetlands with ＂good＂ health accounted for 37.3% of the total number of key wetlands, those with ＂moderate＂ health accounted for 57.4% and ＂poor＂ for 5.3%. Overall, the wetland ecosystem health is in normal situation, some wetlands with significant importance were under threat to different extents, mainly reflected in water pollution and irrational utilization, to which attention should be paid by government agencies.
