瑶湖水环境容量的研究

Study of water environmental capacity in Yaohu Lake

通过对瑶湖水质现状的调查,得出其绝大多数水域COD已属地表水Ⅲ类,总磷、总氮含量偏高(总磷最为显著),已达富营养化水平.对瑶湖COD、总磷、总氮水环境容量进行计算,得出已利用环境容量均超过瑶湖的承载能力,保护瑶湖势在必行.

Through water quality analysis in Yaohu lake, we found that COD in most water area can be catergorized into surface water Ⅲ . The total content of phosphor and nitrogen is so high （total phosphor is marked） that it has reached eutrophication level. By calculating the water environmental capacity, we come to the conclusion that the utilized environmental capacity has exceeded the carrying capacity of Yaohu Lake. Therefore, it is imperative to protect Yaohu Lake.
