摘　　要：山地、绿洲、荒漠是干旱区三大地理景观,三者通过生态资源耦合层、生态经济系统耦合层、农业产业系统耦合层及生态地理耦合层的叠加作用,最终可使绿洲系统功能放大。提出了山地,绿洲,沙漠各子系统应给予重新定位,才能合理高效发挥山盆系统的整体功能。进一步确定山盆系统不同生态-经济分区的功能定位:即山地-基础资源的维持保护功能(突出对山地的生态保护作用);绿洲-特色资源的经济高效功能(突出对绿洲要充分发挥资源优势,并进行经济高效转化);沙漠-特殊资源的开发保护功能(突出要发挥沙漠特殊的热量资源功能,并加以利用)。Mountain,oasis,desert were the main geography landscape in arid land.Among which,ecology and economic function of the whole system should be amplified through superposition effect of the coupled layer of ecology resources,ecology economic,agro-industrialization and eco-geography,and which will be enable to improve function of oasis system ultimately.It is suggested that mountain-basin system should be endowed with the new function repositioning so as to further play a rational and efficient overall function.This research also confirmed the function repositioning of mountain,oases and desert system.That is to say,mountain-maintain and protection of ecological resources（to highlight the ecological protection of mountain）;oasis-eco-economic development of resources（to making use of the prominent resource and convert efficiently）;desert-exploitation and protection of resources（to emphasis on exploiting and utilizing special resources of desert）.
