高效节水等技术措施对石羊河流域重点治理的效应分析

Studies on effects of major harnessing projects and high efficient wat er-sav ing and ecological recovery technologies

通过调查石羊河流域主要作物、种植方式、灌溉方式、结构比例、用水效益等,并收集2007年以来流域年用水量和相关国民经济资料,分析了流域重点治理实施效果与效益,总结提出了设施农牧业、耕作制度、技术集成、新品种引进等4种新型高效节水集成技术与应用模式,作为流域重点治理效益显现和水资源持续利用、生态修复的有效途径。

Achievements and benefits of river basin management are evaluated through investigation on main crops, planting pattern, irrigation methods and water utilization as well as data collection on annual water consumption and national economy of the river basin since 2007. Four integrated water-saving technologies of new type for increase of water efficiency and application models are summarized, namely structural agriculture and animal husbandry, cropping system, technology integration and introduction of new species, which are regarded as effective ways of maximize benefits, sustainable water resources utilization and ecological restoration.
