摘　　要：水土资源的开发始终是绿洲农业发展的核心问题,通过对冲积洪积扇绿洲、冲积平原绿洲、干三角洲绿洲等绿洲不同生态区水土资源空间组合差异及水土资源的开发特点分析,提出了不同生态区水土开发利用要点,认为在冲积扇及冲积平原区域,通过合理井灌井排、人工种植草场及机械化除盐等技术进行恢复盐渍化弃耕地为主来扩大耕地,避免重新开荒后又弃耕的发生;在流域下游干三角洲及沙漠边缘区域,通过高效节水技术防止地下水位抬升,造成土壤次生盐渍化,为绿洲农业资源的优化配置和农业结构调整提供理论依据。The exploitation of water and soil resources is always the core problem of oases agriculture development. In the article, we analyzed the space combinations and characteristic of water and soil resources in alluvial-fan oases, alluvial-plain oases and delta oasis, and put forward the major way of exploitation of water and soil resources in different ecological area of Oasis. In the alluvial and flood plain, some high techniques such as high efficient water-saving, well irrigation and drainage, vegetation rebuilding techniques should be practiced to recover and reconstruct the abandoned land. In delta area located at the lowest reach and the area of the desert edge, we should prevent the elevation of groundwater and soil salinization through the technique of high efficiency water-saving. To adjust the agricultural structure and advanced techniques in developing resources potentialities.
