西南地区河流灌溉发展规划研究

Irrigating development plan of rivers in Southwest China

西南地区河流一般地跨多个不同的气候带,差异大且各具特色,灌溉规划不仅要在总体上统筹区域粮食安全、农民增收和生态安全问题,还要因地制宜,突出重点。所研究的流域在西南地区具有较强的代表性,分析了其灌溉发展现状与发展需求,探讨了既符合现代流域综合规划要求,又契合西南地区实际情况的流域灌溉发展模式。灌溉发展规划实施后,该地区农田水利建设的状况将得到改善,水资源供需矛盾也将得到缓解,而且,粮食安全将得到保障。

The rivers in south - western area of China cross difterent climatic zones, so their d^tlerences are slgnmcant, m me irrigation planning, the issues of food security, income increasing of farmers and ecological security should be considered and principle of positioning on local conditions and prioritizing key issues is stressed. A representative basin in the southwest region is selected for analysis of present irrigation condition and development requirement, and the basin irrigation development mode which not only meets modern basin comprehensive plan, but also conforms with practical condition of southwestern region. After the implement of the irrigation development plan, the situation of construction of field water conservancy is improved, the imbalance of water supply and requirement are alleviated, and the food security is ensured.
