Fuzzy Comprehensive Evaluation of Hydro-ecological Health Condition in Dongliao River Basin
摘要
Abstract
According to the survey of the Dongliao River hydro-ecological condition, the hydro-ecological health was evaluated, and the hydroecological health comprehensive evaluation was divided into four norms, namely riparian zone condition, water environment condition, sediment condition and aquatic organism condition. Moreover, 19 indicators such as the riparian vegetation diversity index,content of heavy metals in sediment, chemical oxygen demand (COD),total phosphorus,total nitrogen,phytoplankton diversity index,etc. Were selected to establish an integrated assessment index system that included rule hierarchy and index hierarchy. Based on these indices, analytic hierarchy process method was applied to evaluate the weight of each indicator,membership function was constructed and used to determine the degree of membership of each index. Finally, the hydro-ecological health conditions of 18 samples were assessed using fuzzy comprehensive evaluation. The results show that the assessment results in 10 of 18 samples are "sick" level,5 samples are "critical" level,1 sample is "sub healthy" .while only 2 samples are " healthy" level, the present status of hydro-ecological health condition in Dongliao River is bad. It is also suggested that the level of hydro-ecological health condition in Dongliao River basin is deeply affected by the flood. This study provides scientific evidence to the government for the work of management and the protection of Dongliao River.关键词
