【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.更多还原

【Abstract】 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.更多还原
