摘　　要：受地形影响 ,新疆玛纳斯河流域自然带呈明显的系统结构 ,形成了山地、绿洲、荒漠流域生态系统。山地是流域的水源地 ,从水、土等方面制约绿洲的物质循环 ;荒漠是流域的生态屏障 ,从光、热等方面决定着绿洲的能量平衡。绿洲是流域水、土、光、热资源的集成地 ,是干旱区人类生产、生活的理想场所。绿洲建设已完全改变了流域生态面貌 ,使流域开发带有明显的技术倾向 ,并最终决定着流域生态建设的演变。Influencing by the landform, naturalization of Manas River valley display obvious circling pattern and form relevent mountain,oasis,desert eco system.Mountion is the resource of water and soil, restricting the mater cycling of oasis. Desert is the ecologic screen of the oasis, restricting the power balancing from the light and warm. Oasis is the forming of water, soil, light and warm of volley. It is the proper land of the produce and love. Oasis constructing had changed the eco environment of volley. Making the development of volley has the obviously technological tendence, and determine evolving of oasis construction.
