作者 刘冬启 熊邦喜 《水利渔业》 2000年第3期41-42,47,共3页
灰色聚类法是在模糊聚类的基础上发展起来的新的聚类方法。本文选取 TP、TN、COD 3项因子作为评价因子 ,对石河水库的水质营养状态进行了评价 ,结果表明石河水库已处于中营养时期。

2014年和2015年春(5月)、夏(8月)季对漳泽水库浮游动物进行了4次调查,共检出浮游动物53种(原生动物20种,轮虫18种,枝角类7种,桡足类8种)。浮游动物物种数夏季较多,2014年和2015年夏季分别为34种和35种;春季较少,分别为17种和21种。2015... 2014年和2015年春(5月)、夏(8月)季对漳泽水库浮游动物进行了4次调查,共检出浮游动物53种(原生动物20种,轮虫18种,枝角类7种,桡足类8种)。浮游动物物种数夏季较多,2014年和2015年夏季分别为34种和35种;春季较少,分别为17种和21种。2015年夏季浮游动物总丰度最高,为24 396个/L;2014年春季浮游动物总丰度较低;为1 435个/L;漳泽水库浮游动物丰度主体为原生动物和轮虫。四次调查浮游动物Shannon-Weaver多样性指数变化范围为2.25~3.60,判断水质为轻污染至清洁状态,综合营养状态指数最终初步确定漳泽水库水质为中-富营养型。 展开更多

Samples were taken, between 2013 and 2014, in the reservoirs "Algodoeiro" and "Gloria" in Sergipe, Brazil. TSI (Trophic State Index) and WQI (Water Quality Index) were used. It was determined the parameters such as conductivity, dissolved oxygen, total nitrogen, total phosphorus and chlorophyll. TSI has been applied, in "Algodoeiro", which was classified as mesotrophic. With the increase of rainfall in 2014, this reservoir changed its condition to eutrophic. "Gloria" reservoir was already classified in super-eutrophication. Regarding the WQI, the reservoirs were classified in Class IV, indicating a critically degraded condition. 展开更多
