摘　　要：以渭干河和库车河下游戈壁绿洲区为对象,利用区域化探和土地质量地球化学调查数据,对渭干河和库车河流域Ti,Cu,Mn,S,Cd,Hg元素含量及分布特征进行研究。结果表明,渭库绿洲土壤理化性质受成土母质影响,很大程度上继承了河流冲积物的特征;下游生态与上游地质环境密切相关,下游土壤中重金属元素Cd,Hg主要来源于上游成土母质。矿业开发活动对下游生态环境造成直接影响。Targeting the Gobi Oasis in the lower reaches of Ugan-Kuqa River,Using regional geochemical exploration and land quality geochemical survey data,The content and distribution characteristics of Ti,Cu,Mn,S,Cd,Hg elements in Ugan-Kuqa River basins were studied.The results show that the physical and chemical properties of soil in the Ugan-Kuqa River Delta Oasis are affected by the parent materials of soil formation,To a large extent,It inherits the characteristics of river alluvium;The downstream ecology is closely related to the upstream geological environment,The heavy metals Cd and Hg in the downstream soils mainly come from the parent materials of the upstream soils.At the same time,There are signs that,Mining development activities will also have a direct impact on the downstream ecological environment.
