选择克里雅河流域于田绿洲为研究区，以绿洲土、盐渍土、棕漠土及风沙土等4种类型土壤为对象，分析了土壤表层养分、水盐因子的特征，结合通径分析方法研究了养分与水盐的相关关系。结果表明：不同土壤类型土壤养分与水盐因子差异性显著。通径分析显示，土壤水分对有机质含量和全氮的直接作用显著，地下水埋深通过土壤水对有机质和全氮的间接通径系数较大；水盐因子可能不是影响有效磷的主要因素；虽然水分因子对速效钾的直接通径系数较大，但其综合影响较校?盐分因子对速效钾的影响较大。

Soil samples from 0-20 cm layers under different soil types (oasis soil, brown desert soil, saline soil and aeolian sandy soil) were collected across Yutian oasis of the Keriya river watershed. By analyzing soil nutrients and water-salt properties, this study made an attempt to discuss the relationships between soil nutrients and water-salt properties by the methods of path analysis. The results showed that there were differences among different soil types in terms of soil nutrients and water-salt properties. Path analysis showed that soil moisture had a significant relationship with soil organic matter and total nitrogen while groundwater depth was indirectly related to soil organic matter and total nitrogen. Water-salt properties were not the important factors affecting available P. The available K was determined largely by salt factors though the direct path coefficients to water properties were bigger.
