摘　　要：自2005年6-11月份与2006年3-12月份对王家厂水库的水质理化特性的变化进行了测定,并进行相应的渔业评价,结果表明:一、王家厂湖水清澈,透明度较高在101cm,溶解氧丰富,水呈弱碱性;二、水体中主要营养元素氮含量较高,磷偏低,氮磷比为76:1,明显缺磷;综合所有数据,可以发现,湖水的理化性质都比较好,能够进行良好的渔业发展,但是水体中各项营养指标显示王家厂水库已达到富营养化类型,为保持渔业的可持续发展,重点解决水体的富营养化问题已迫在眼前.The water＇s various physics and chemistry characteristic property were analysed in June- Nov. of 2005 and March- Dec. of 2006, and also the fishery market was estimated. The result as follows： 1, the water in Wangjiachang is clear and transparent, the transparent degree is about 101cm; and it is rich in resolving oxygen and water has slightly alkaline value. 2, As to the nutrition element in the water, nitrogen has a higher content while phosphorous has a lower content, which is 76： 1. It is obviously showed it lack of phosphorous in the water. According to the statistics in below writings, we can see that water＇s physics and chemistry characteristic is good and can develop a good prospect in fishery market. Nevertheless, each nutrition norms revealed that the reservoir is reached a style of eutrophication. In order to keep a sustainable development in fishery marker, the eutrophication problem have to be solved.
