摘　　要：首先概述了景观地球化学在国内外的研究现状,然后以干旱区内陆河的典型代表——塔里木河干流为例,对地表水系统的水文地球化学特征、土壤元素的地球化学特征及不同植被类型的生物地球化学特征分别进行了系统分析。最后对影响塔里木河干流景观地球化学环境演变的自然及人为因素进行了分析。自然因素包括气候、地质、地形地貌及水文地质地球化学环境因素等,而在塔里木河流域开展的大规模水利工程及人类的农业生产活动是该区景观地球化学环境演变的重要动力因素。This article has first outlined the current situation in the study of landscape geochemistry both at home and abroad,and then took the Tarim River,a typical representative of Inland River in arid zone as the case study.The hydrological geochemistry characteristic of surface water,the soil element geochemistry characteristic and the different vegetation type biogeochemistry characteristic were analyzed separately.Finally,the natural and human factors which affected the evolvement of landscape geochemistry environment were analyzed.Natural factors includes climate,geological,terrain landform and hydrology geology geochemistry environmental factor and so on,and large-scale hydraulic engineering and humanity＇s agricultural production activity are important power factor in the evolvement of landscape geochemistry environment in the Tarim River basin.
