为有效防止南水北调总干渠两侧一定范围内的工业、农业、生活污染物和其它污染物进入总干渠,预防突发性污染事故和人工活动诱发事故对总干渠水质的污染,重点是防止受污染的地下水进入总干渠污染调水水质,沿线各省市在中线工程总干渠两侧划定了水源保护区。目前,为促进沿线地区经济结构的战略性调整,推动防护林带、城镇园林绿地、生态农业建设,提出了在中线工程总干渠两侧建设生态带规划,确保调水水质安全,打造调水沿线生态屏障。
In order to effectively prevent the entry of industrial, agricultural, domestic pollutants and other pollutants into the main canal within a certain range on both sides of the main channel of the South-to-North Water Diversion Project to prevent the pollution of water quality in the main canal due to unexpected accidents and induced accidents, the emphasis should be on preventing pollution Of groundwater into the main canal pollution water quality adjustment, along the provinces and cities in the midline of the main canal on both sides of the designated water source protection zone. At present, in order to promote the strategic adjustment of the economic structure along the region and promote the construction of shelterbelt, urban and rural green space and ecological agriculture, it is proposed to construct an ecological belt plan on both sides of the main canal of the midline project so as to ensure the quality and safety of water diversion and water diversion, barrier.
