摘要
新疆焉耆盆地农田土壤次生盐渍化程度严重,分布面积大,灌溉用地表水量多,排碱渠密布,排碱渠大量高矿化度水排入博斯腾湖,使湖水水质受到影响,其生态环境极其脆弱。本文试图从土壤次生盐渍化的形成机制、成因分析,采用开采地下水、竖井排灌,置换地表水,结合调整农业产业结构等综合治理方法,从根本上解决盆地土壤次生盐渍化问题,以减少高矿化度水向博斯腾湖的排放,使盆地生态环境向良性方向发展。
Secondary salinization of soils in the Yanqi Basin in Xinjiang is significant and the area of salinization is large. Irrigation in this area relies on surface water. Alkali-draining-canals carried water with high total dissolved solids to the Bositeng Lake, resulting in the degradation of water quality of the lake. Eco-environment of the basin is quite fragile. Formation of the secondary salinization of soils in the Yanqi Basin is analyzed. Control measurements such as pumping groundwater, drainage and injection through wells, exchange of surface water and adjustment of agricultural structure are proposed to solve the problem of secondary salinization in the basin. As a result, the discharge of water with high total dissolved solids to the Bositeng Lake will be decreased, and a good eco-environment in the basin will follow.
