摘　　要：[目的]研究和田河流域不同景观下土壤肥力差异。[方法]通过对和田河流域不同景观下土壤肥力元素含量的测定,总结不同景观土壤肥力的变化规律。[结果]和田河流域各景观间土壤肥力元素具有空间变异性。N、P含量:绿洲>过渡带>荒漠;而由于盐渍化的影响K含量:荒漠>过渡带>绿洲。土壤养分分布是由结构性因素和随机性因素共同作用的结果。[结论]为和田河流域生态环境的治理和资源合理开发提供依据。[ Objective] The research aimed to study the difference of soil fertility among different landscapes in Hotan River Basin. [ Method ] By detecting tile amount of the elements of different landscape soil fertility in Hotan River Basin, the roles of change of different landscape soil fertility of the Hotan River Basin was summarized. [Result] The soil fertility element among different landscapes in Hotan River Basin had spatial variability.The N and P contents were as follow： Oasis 〉 transitional zone 〉 hungriness,and the K content was as follow： Hungrhless 〉 transitional zone 〉 oasis.The soil nutrient distributing resulted in the structural and random factors. [ Conclusion] The study provided reference for ecological environmental government and the economical development in the Hotan River Basin.
