阳宗海水质污染及其控制

由于近年Ｎ、Ｐ输入、输出失衡，大量营养盐滞留湖中，加以电厂温排水影响，阳宗海水体恶化加剧，两年出现大面积水华；且湖中鱼类结构不合理，数量偏少，导致水质变化。为此，必须取缔网箱及高密度堰塘养鱼，实施环湖截污，降低电厂排水温度，调整鱼类种群结构。

Water Pollution in Yangzonghai Lake and Its Control

Due to the imbalance of inflow and outflow of N and P, Large amount of nutrient salts are remained in the lake. The warm water is discharged from power plants,water deterioration of Yangzonghai Lake is witnessed and large area of water bloom occurred in two consecutive years. In addition, fish in the lake is few which leads to water deterioration. In this case, cage cultivation should be cancelled while high density fish cultivation in pools should be encouraged. Pollution check Should be implemented around the lake, water discharge temperature in power plants should be lowered and fish structure should be readjusted.
