| 摘 要： | 于 2 0 0 0年 1～ 12月分析了浙江省象山港网箱养鱼区的水质变化规律 ,结果表明 :网箱内NO3 - N、NH4 N、NH3 N和IN全年平均值均明显高于鱼排外 ;从全年平均值来看PO43 - P不超标 ,但 2月和 10月PO43 - P高于四类水质标准 ;IN含量在全年均严重超标 ,且网箱内的值一般高于鱼排外 ,尤其是由养殖鱼类排泄导致的NH4 N和NH3 N更是如此。 |

| Abstract: | Changes of water quality in net aquaculture area of Xiangshan Harbor, Zhejiang were analyzed from Jan. to Dec. 2000. The whole year average values of NO 3 - N, NH 4 N, non ammonia N and IN in webs were higher than out of the webs. Although the whole year average values of PO 4 3- P were not higher than the marine a quaculture standard, but the values in both February and October we re higher than the fourth standard. TN concentrations were seriously higher than the standard. IN especially NH 4 N and non ammonia N in webs were higher than out of webs. |
