摘要: 长期利用高矿化度地下水灌溉造成沙质土壤的次生盐渍化是塔克拉玛干沙漠腹地建立人工生态系统的主导限制因素之一。据1992年与1994年在塔克拉玛干沙漠腹地满参与中三点2年的试验研究结果认为: 在灌溉水的适宜应用条件下, 利用矿化度为4g/L~5g/L的地下水灌溉种植瓜果蔬菜和固沙植物是能够成功的; 生长季内土壤含盐量<0.1%。

Abstract: Abstract With respect to establish artificial ecosystem itself, one of key limiting factors is soil salt stress which caused by irrigating underground water with higher mineralization degree for long term due to local intense evaporation in the hinterland of Taklimakan Desert. The experimental results for two years show : under suitable application conditions of sprinkling water, it can succeed in making use of underground water with about 4 g/L~5 g/L of mineralization degree to irrigate vegetable and sand-binding plants, and salts content in the soil was lower than 0.1 within the growth phase of plants.
