青海省黄河上游沿岸农田的 土壤盐渍化，已成为该区农业发展的严重限制因素．研究主要选择了盐渍化严重的黄河上游 龙羊峡库区的农田．该区农田土壤为氯化物－硫酸盐盐土；土壤剖面盐分分布为两种类型，即 盐分表面聚集型和通体含盐型．土壤盐渍化成因主要有气候、灌溉水矿化度、土壤母质、灌溉制度和地形．当地土壤盐渍化的解决途径主要是生物措施，相应地配合水利与造林等工程 措施．
Soil salinization in farmland along the upper reaches of the Yellow River in Qinghai Province has become a serious limiting factor for agricultural development in this area. The study mainly selected the farmland of Longyangxia reservoir area in the upper reaches of the Yellow River with serious salinization. The soil of this farmland is chloride-sulphate salt soil. There are two types of salt profile in the soil profile, that is, salt surface aggregates and all-salt salts. Causes of soil salinization are mainly climate, irrigation water salinity, soil parent material, irrigation system and topography. The solution to the local soil salinization is mainly biological measures, correspondingly with engineering measures such as water conservancy and afforestation.
