摘　　要：水资源是粮食生产不可或缺的物质基础。该文利用2002～2008年统计资料,采用描述性统计和定量分析的方法,分析了海河流域水资源利用现状与对农业生产的影响程度。结果表明:该区域农业水资源供给扩张方面的范围十分有限,农业水资源与农业生产呈正相关关系,即农业灌溉用水每增加1%,农业产值将增加0.0111%。因此合理优化投入要素的配置关系,是稳定粮食生产,保证粮食安全的主要途径。Water is an essential material basis for food production. Based on the statistics data of 2002 ~ 2008, this paper analyzed the impact of HaiHe River Water Resources on agricultural production using descriptive statis- tics and quantitative analysis method. The results showed that： regional agricultural water supply was very limited, water resources for agriculture was positively correlated with agricultural production, that is, 1% increase of irrigation water can increase the agricultural output by 0. 021%. So optimal allocation of water resources was the main way to ensure food production and security.
