西北干旱内陆河区水资源利用与绿洲演变规律研究──以石羊河流域下游民勤盆地为例

Water Resources Development and Oasis Evolution in Inland River Basin of Arid Zone of Northwest China ──A Case Study: Minqin Basin of Shiyang River

水资源的开发利用对我国西北干旱内陆河区的生态环境具有重要的影响，天然植物的生 长与种群随地下水位和阵水的变化而演变。由于良好的绿洲生态系统是实现于旱内陆河区社会。 经济和环境可持续发展的基本前提，在西部大开发中，必须综合考虑水资源开发利用与绿洲生 态环境保护问题，本文以民勤盆地为例，研究典型干旱内陆河区水资源利用、农业灌溉与绿洲 演变的转化关系和基本规律。

Water Resources development plays a key role in the ecological environment of inland river basins of arid and semi-arid zone in Northwest China. According to experimental observation, it is clear to see that growth of natural plants have a close relation with local groundwater level. A good ecological system in the oasis of the zone is the precondition for sustainable development, therefore, the water resources development and ecological environment protection should be integrated in one system in the Grand Western Development. As a case study, the egulation and relationship of water resources development, irrigation area arrangement and oasis evolution have been analyzed in Minqin, the downstream of Shiyang River in Hexi Corridor of Gansu Province (It will provide the foundation of analysis for rational irrigation and environment protection in Minqin Basin).
