A Study of the Effects of Nitrogen and Phosphorus on Aquatic Ecosystem Health Status

Abstract:

Eco-exergy which is a thermodynamic indicator is applied to assess the ecosystem health status of QiXing Lake. And effects of nitrogen and phosphorus on ecosystem health status have been investigated. The results indicate that the ecosystem which contains macrophytes has the better health status than that does not contain macrophytes when they have the same concentration of nitrogen or phosphorus. The ecosystem health status decreased as the concentration of total nitrogen increased when the ecosystem contains macrophytes. However, the ecosystem health status has not significant change as the concentration of total nitrogen increased when the ecosystem does not contains macrophytes. It has the same law for total phosphorus.
