| 摘 要： | 采用灰色理论对二龙山水库水质变化趋势进行评价,考虑相关因素选取高锰酸盐指数、BOD5、总氮和总磷作为水库的主要污染因子。通过1996～2003年污染因子的权重系数ei计算表明,二龙山水库的主要污染物是氮和磷,属有机污染型。据模糊综合指数zj评价二龙山水库1996～2003年历年水库水质变化,表明二龙山水库水质质量在已有的8年期间有所下降,分析其原因与二龙山水库作为国家4A级旅游区的开放是分不开的。

| Abstract: | Applying gray theory to variational trend evaluation of water qualit y of Erlongshan reservoir, CODMN, BOD5, TN and TP were selected as dominating co ntamination factors taking related factors into account. We found that the prima ry pollutants were nitrogen and phosphorus by calculation weight coefficient of contamination factors from 1996 to 2003. It means Erlongshan reservoir belongs t o organic pollution type. According to fuzzy general exponent zj evaluating vari ational trend of water quality of Erlongshan reservoir water from 1996 to 2003, we concluded that Erlongshan reservoir has showed descending trend in the past 8 years. The results were related to the open of Erlongshan reservoir as the 4A n ational tour resort. |
