摘要
以松嫩平原若干典型湿地为例,在阐释湿地脆弱性内涵的基础上,分析了本区典型湿地脆弱性的成因,并采取定性与定量相结合的方法,对典型湿地进行了评价.评价中依据湿地生态特性及演化规律建立评价指标体系,利用层次分析法确定指标权重,利用综合指数法计算湿地的脆弱度,为保护松嫩平原的湿地环境,合理开发、利用湿地资源提供了依据.
Taking some typical wetlands of Songnen Plain as an example,and based on the explaination of wetland frangibility's connotation.In this paper,the cause of formation about wetland frangibility was analysed.And adopting the method of qualitative analysis associated with quantitative analysis,the typical wetlands of Songnen Plain are appraised.In the appraisement,based on the ecological traits and evolutionary law of wetlands,the index system of appraisement is built.The values of weighing the rlative importance of the indexes are established by the analytic hierarchy process and the degree of fragility is computed by the method of multi~indexes.All of them provide the gist for protecting the wetland environments and developing and suing the wetland resources in Songnen Plain.
