【摘要】 在2013年11月至2014年5月对洪潮江水库进行水质和水生态调查,调查结果表明,洪潮江水库处于中营养化状态,总磷变动于0.053~0.103 mg/L之间,总氮变动于0.53~0.81mg/L之间,浮游植物密度平均为134.70×104ind./L,生物量为1.47mg/L,浮游动物密度平均为883 ind./L,生物量为2.05mg/L,库区水土流失和工农业污染是营养盐主要来源,库区生态养殖在枯水期磷含量增加的情况下,抑制了浮游生物的生长,防止了"水华"的产生。更多还原

【Abstract】 An investigation included water quality and aquatic ecosystems was carried out in Hongchaojiang reservoir,fromNovember 2013 to May 2014.Survey results showed that the Hongchaojiang reservoir was mesotropher, total phosphorus changes in the0.053~0.103 mg/L,TN movements between 0.53~0.81mg/L,phytoplankton density averaged 134.70×104ind./L,biomass was 1.47mg/L,zooplankton densities averaged 883 ind./L, biomass was 2.05mg/L, industrial and agricultural pollution and soil erosion is the main source of nutrients, ecological farming inhibits the growth of plankton, prevents the "blooms" generation when phosphorus contentincreases in the dry season.更多还原
