| Abstract: | Based on the Pressure-State-Response (PSR) model and properties of Nansihu Lakes, health level of Nansi Lake is evaluated in this paper. Choosing people consistency, water supply of industry and agriculture, environmental purification, fish resources, nutrient cycling factors which can reflect pressure, state and response, an evaluation system has been set up. The proportion of the indicators is confirmed by experts and experience, and the assessment criteria are based on related national standards, then complete evaluate model is put forward and the health index of Nansihu Lake is figured out. According to health index, the health state of Nansihu Lake is determined. As showed by the results, the health assessment index of Nansihu Lake is 0.4051, which belongs to a "sub-healthy" state. |
