| 中文摘要: |
| 通过对连云港市宋庄镇有机海水养殖基地围塘海水氮磷污染负荷的实验分析、比较和验证研究,提出了新的计算N、P污染负荷的方法—＂新化学分析法＂。研究表明,新化学分析法的计算结果更符合实际情况,且围塘海水养殖1公顷面积1个养殖周期的污染负荷分别为：混养组,氮42.1kg,磷10.01kg;单养组,氮85.4kg,磷20.6kg;同时证明海水混合养殖较单一养殖更能提高海水围塘生态系统的物质转换效率,减少环境污染。 |

| A new calculation method of N, P pollution loads --＂new chemical analysis method＂ was proposed through the experimental analysis, comparison and validation studies about seawater nitrogen and phosphorus pollution loads of organic seaculture base in Song Zhuang town. The results suggested that the reckoning of the new method is more realistic, and the pollution loads of seawater enclosed pond aquaculture one ha area one culture period are as follow： polyculture group with nitrogen of 42.1kg, phosphorus of 10.01 kg; monoculture group with nitrogen of 85.4 kg, phosphorus of 20.6kg. and it is proved that seawater polyculture is more efficient than monoculture in material conversion and environmental pollution reduction. |
