河西走廊流域治理的科学问题及其思考

The key problems and challenges on the river basin governance in the Hexi Corridor,Gansu,China

针对河西走廊三流域治理,从水资源承载能力、社会经济发展模式、水资源利用秩序等方面,剖析各流域产生生态问题的科学必然性,以及流域治理手段的针对性。从黑河、石羊河流域治理的效果及流域演化基本规律出发,提出河西走廊三流域后治理时代可持续发展在气候变化、经济转型和粮食安全等方面的科学思考。

The inevitability of the occurrence of ecological issues and targets of the governance of the Three River Basins in the Hexi Corridor （the Corridor West of the Yellow River） were analyzed in terms of water resources carrying capacity, socio-eco- nomic development patterns and the order of water resources use. Based on both the effects of governing the Heihe River and the Shiyang River Basin and on the basic rules of river evolution, the key problems and challenges on the sustainable development during the post-management period of the Three River Basins in the Hexi Corridor were proposed in terms of climate change, economic transition and food safety.
