摘要
湘潭电厂温排水对湘江湘潭电厂江段大型底栖无脊椎动物 (以下简称底栖动物 )种类组成和数量变化的影响表明 ,在强增温区底栖动物不能生存 ;自然水温在 2 6℃以下的季节里 ,中、低增温区底栖动物种类和数量比自然水体要丰富 ,多样性指数值相应增高 ;突然停止温排 ,增温区内喜温动物有可能受冷冲击而死亡。
The influence of drained hot water from Xiangtan Electrical Power Factory upon the composition of large spineless bethon animal kinds and the changes of animal guantities in Xiangtan Electrical Power Factory part of the Xiang River (abbreviated “bethon animals'below) show: bethon animals can't live in the areas where the water temperature is raised a lot; in the seasons with natural water temperature under 26 centigrades ,the kinds and guantities of bethon animals in the areas where the water temperature is raised a little are much richer than those in natural water, and the varicty of index is relatedly raised; if we stop draining hot wter into the river suddenly ,the animals which like to live in warm water in the areas where the water temperature has been raised may die from cold lash.
