【摘要】 从分析流域降水量与南四湖区水质的相关关系入手,根据枯水的2002年湖区7个监测断面的水质监测结果,采用综合污染指数法(P值法)对各监测断面及南四湖区的总体水环境质量进行了综合评价。结果表明,由于2002年济宁市降水稀少,南四湖区水质较往年有所下降,属于轻污染,流域降水量与湖区水质相关性显著。更多还原

【Abstract】 Based on analyzing the relation between precipitation and water quality of the Nansihu area, according to the water quality monitoring results of 7 sections along Nansihu area in dry year in 2002, using the integrated polluted index (P value), this paper made comprehensive evaluation about the total water quality of each monitoring sections and the Nansihu area. The results showed that water quality in the Nansihu area was slightly polluted comparing with past years because of the rare amount of precipitation in this year, the relation between precipitation and water quality of the Nansihu area is very distinct.更多还原
