黄河三角洲地区农业用水水平分析

Analysis of Agricultural Water Utilization Level in The Yellow River Delta

以地处黄河三角洲腹地的东营市作为研究区域,在全面调查分析当地水资源状况、农业种植结构、灌溉工程和灌溉方式的基础上,引入农灌节水指数法研究评价当地农业灌溉节水水平。结果表明,东营市的农灌节水指数达到1.65,农业用水水平高于沿黄两岸典型引黄灌溉地区平均用水水平,但相对于农灌节水指数达到2.62的济宁市差距明显,农业灌溉的节水潜力有待挖掘。

Taking Dongying city which is located in the hinterland of the Yellow River Delta as the research area,we evaluate the local agricultural water-saving irrigation on the basis of analyzing the local water resources, planting structure of agriculture, irrigation engineering and irrigation methods. The results show that the local agricultural water-saving irrigation index reaches up to 1.65 ,which is higher than the average agricultural water utilization level of typical irrigation cities along the Yellow River, however, obviously lower than that of Jining city,whose index reaches to 2.62. The agricultural irrigation water saving potential of Dongying city remains to be further excavated.
