【Abstract】 Adopt SPSS software,to statistical analysis on the water quality monitoring data month after month in 2003～2004,the result shows that the more obvious space difference of the water quality pollution in Daotian river reservoir and Limin reservoir.And different pollutant contribute rate is not alike with each other in water pollution of Daotian river reservoir and Limin reservoir,TP and excrement large intestine fungus of portion more heavy and the contribute rate is up to 77%.On this basis,utilize weighted comprehensive pollution index to make appraisal on the present condition of water body pollution,result shows water quality belong to slight pollution in the reservoir,then water quality in the intake of drinking water measure up to the Ⅲ type water quality standard in the"environmental quality standards for surface water(GB3838-2002)"and make suggestion of strengthening water environmental protection.更多还原
