发展生态农业是保护抚仙湖的关键措施

根据调查结果,抚仙湖水污染特征主要以面源污染为主,面源入湖污染物TP、TN、COD Cr的入湖贡献率分别为76.3%、80.4%、94.7%。因此,保护抚仙湖控制面源污染是关键。而面源污染主要来自农村生活和农业生产,只有在湖盆区实施产业结构调整,大力发展生态农业、生态林业,实现循环型农业经济,从源头控制大量有机物、TN、TP等污染物入湖,才能有效保护抚仙湖水质。

The Development of Ecological Agriculture is the Key Measure of the Protection of Fuxian Lake

According to investigation results, non-point source pollution is the major feature of Fuxian Lake＇ s pollution. The sources of non-profit source pollution are TP, TN and CODer, and each of them takes up to 76.3%, 80.4% and 94.7% respectively. Therefore, controlling Fuxian Lake＇ s area source is the key action of the entire project. The sources of non-profit source pollution are mainly from the residue of agri-cultural activities and rural livelihoods. In order to protect the water quality of Fuxian Lake efficiently, implementing industrial structure ad-justment in the lake basin area, vigorously developing ecological agriculture and ecological forestry, achieving circular agriculture economy and preventing organism, TN, TP and other related pollutants from being originally released into Fuxian Lake are necessary measures that required to be accomplished.
