Abstract

Abstract: Based on the quarterly water quality data of Qingshan National Wetland Park from 2014 to 2016, the trend of water quality change and pollution situation in Qingshan National Wetland Park were comprehensively analyzed and evaluated by using the nutrition status index and grey-mode identification model. The results showed that the surface water of Qingshan National Wetland Park were the Ⅱ class water quality standards on the whole, kept in a "poor nutrition" to "nutrition" in the degree of eutrophication status, and some years could even reach the Ⅰ class water quality standard, water body’s self-healing ability was stronger. It can be seen that the water environment management measures of Qingshan National Wetland Park enable the water area of the wetland to achieve the environmental function and protection goal of the surface water area, the ecosystem is in good health, and the function of the wetland ecosystem is guaranteed.

Key words: wetland park, water quality assessment, nutritional status, grey-mode identification model
