摘　　要：在开展柘林湖污染源现状调查的基础上,参照国内外相关湖泊污染负荷估算研究方法,采取调查系数法估算柘林湖非点源氮磷的入湖负荷。结果表明,水产养殖、农业种植业流失、农村生活和畜禽养殖污染是柘林湖流域非点源污染入湖氮的主要来源,分别占入湖氮总量的48%、30%、16%和6%;水产养殖污染是入湖磷的主要来源,占64%,其次为畜禽养殖、农村生活和农业种植业流失,分别占17%、10%和9%。On the basis of carrying out all investigation of Zhelin Lake pollution source status, referring to domestic and foreign lake pollution load estimation methods, survey coefficient method was adopted for estimation of Zhelin Lake non-point source nitrogen and phosphorus load into the lake. The results showed that aquicuhure, planting loss, rural life and pollution from livestock and poultry breeding are main sources for Zhelin Lake non-point source nitrogen, accounting to 48% , 30%, 16% and 6 %, respectively. Aquicuhure pollution is the main source for phosphorus, accounting to 64%, following by livestock and poultry breeding, rural life and planting loss with 17% , 10% and 9% , respec- tively.
