中文摘要:

我国农业面源污染的核心问题是水体的氮、磷富集,目前尚无有效的工程治理方法,本研究通过有机水产养殖减轻水体的氮、磷污染。结果表明,有机水产养殖可以有效降低养殖水体的COD、无机氮和无机磷的浓度,有机海水养殖控制污染物排放的效果较有机淡水养殖更明显;有机养殖方式下严格而系统的管理措施及饵料质量的控制可能是减少氮、磷富集的主要因素。

英文摘要:

The core issue of Chinese agricultural non-point source pollution is water nitrogen and phosphorus eutrophication, and there is no effective engineering treatment methods still now. In this paper, organic aquaculture methods to reduce agricultural non-point source pollution were researched. The results showed that, organic aquaculture farming could reduce water concentration of COD, inorganic nitrogen and inorganic phosphorus, and under organic farming, the effect of controlling pollutant discharge in mariculture was more obvious than in fresh water aquaculture. Under the organic farming, strict and systematic organic management and the fish food quality are possibly the primary factors to reduce enrichment of nitrogen and phosphorus.
