HEALTH EVALUATION AND DIAGNOSIS METHOD FOR URBAN LANDSCAPE LAKE WATER ECOSYSTEM

WIPO Patent Application WO/2022/099852

A1

A health evaluation and diagnosis method for an urban landscape lake water ecosystem, comprising: designing an index system as a hierarchical structure, which is divided into a target layer, a criterion layer and an index layer, the target layer representing the comprehensive health index of the urban landscape lake water ecosystem and being used for reflecting the overall level of a health status of an urban landscape lake, the criterion layer reflecting attributes and levels of the health status of the urban landscape lake from different aspects comprising water quality, sediment, biological community and lakeshore zone, the index layer being formed by selecting a plurality of indexes under the criterion layer, and the index evaluation being mainly based on quantitative evaluation, supplemented by qualitative evaluation; specifically dividing various factors influencing the water quality and health of the urban landscape lake, and performing assignment and scoring; determining evaluation weights of the criterion layer and the index layer by using an analytic hierarchy process; obtaining the comprehensive health index of the urban landscape lake water ecosystem according to the score value and weight of each index; and finally, determining the health status of the urban landscape lake according to the comprehensive health index of the urban landscape lake water ecosystem, and formulating corresponding restoration countermeasures.
