南水北调中线工程水源区水质治理与保护的生态措施

Eco-countermeasures on the management of water quality in the water source area of the middle line in the south- to-north water diversion

南水北调中线工程的水源地在丹江口水库流域,其水质达到国家Ⅱ类水质标准 水库的主要污染物为有机物,库区呈现中营养状态 水源区生态环境建设思路包括:大力开展生态林建设;有计划地开展流域综合治理;以生态农业为基础,用现代农业的清洁生产方式,改造区域内落后的农业生产方式;

The water source of the middle line in the south-to- north water diversion is in Danjiangkou Reservoir waters. Its water quality reaches Ⅱ.Organic matter is the reservoir's main pollutant. The reservoir takes on the middle nutrient level. Measures of building eco-environment in the area are as follows: building eco-forest; planned complex management of waters; reforming the backward agricultural production on the base of eco-agriculture by the modern clean one and designing the productive area of eco-environment.
