黄河流域农业水资源与水环境问题及技术对策

The Problems and countermeasures for agricultural water resources and water environment in The Yellow River Basin

对黄河流域农业水资源与水环境现状和存在问题进行了分析,并针对这些问题,提出了改善黄河流域农业水资源利用与水环境安全的技术对策。研究指出,黄河流域水资源贫乏、水质污染严重、灌溉水水质劣化、农业水资源供需矛盾突出,水环境日趋恶化,产生了严重的生态环境问题;而目前我国缺乏有效的农业水资源和水环境监测预警系统,节水农业和水污染防治技术水平低,基础设施落后,信息平台建设不够,农业种植结构和水资源不匹配。今后应加快建立农业水资源与水环境监测预警系统与信息平台,积极推进农业水资源高效利用技术升级,全面提高农业污染防控技术水平,加强农业水环境保护,调整种植结构,建立节水高效种植制度。

This paper deal with the problems about water resources and water environment in the Yellow River Basin, including water shortage, water pollution, and irrigation water quality deterioration. There are still lack of agricultural water resources and water-environment deficient monitoring and early warning system. Technology for water-saving and water environment protection are still poor. Infrastructure condition and information platform need to be enhanced. Cropping systems of agricultural water-saving need to be improved.
