株树桥水库的水是长沙市第二水源,源于大围山第四纪冰川地质遗迹的“冰窖”等形成的中高山湿地,是厚层花岗岩风化壳的孔隙裂隙潜水,因含有有益微量元素优于国家Ⅰ级标准的优质水。但是流域内施用化肥已产生土壤Cd污染,由此将导致水Cd含量增高,这是影响株树桥水库水质的潜在因素。为此建议流域内建设不施化肥、农药的观光农业园,以彻底消除影响水库水质的隐患。
The water of Zhushuqiao Reservoir is the second water source of Changsha City, and is a medium-high mountain wetland formed from the “ice cellar” of the Quaternary glacial geological remnant of Dawei Mountain. It is a pore fissure submerged in a thick granite weathering crust, Beneficial trace elements better than the national standard Ⅰ grade high-quality water. However, the application of chemical fertilizers in the basin has resulted in soil Cd pollution, which will lead to an increase of Cd in the water, which is a potential factor affecting the water quality of Zhushuqiao Reservoir. To this end, it is proposed to build a sightseeing agriculture park without chemical fertilizers and pesticides in the drainage basin so as to completely eliminate the hidden dangers affecting the water quality of the reservoir.
