黄河三角洲灌区农业配水分析

地处黄河三角洲的东营市共有六大农业灌区,由于黄河经常发生断流,且每年的来水量不断减少,因此,对各个灌区进行合理配水是一个亟待解决的问题。由于统计区域边界与灌区边界不一致,论文应用遥感作为辅助数据对统计数据进行了面插值,获得了各灌区的统计数据,然后应用经济学中边际效益原理,计算了各灌区的农业用水边际效益,从而获得了各灌区的农业用水边际效益曲线,根据边际效益曲线建立了黄河三角洲各灌区的农业配水模型。该模型从经济效益最大化的角度较好地解决了黄河三角洲农业水资源的合理分配。

Agriculture water allocation analysis of irrigation regions of the Yellow River Delta

There are six agriculture irrigation regions in Dongying Municipality which is located in Yellow River Delta.Because there is not enough water for the Yellow River in recent years,finding a proper water allocation solution for different irrigation regions has become an urgent issue.Because it is not consistent between the boundaries of counties and irrigation regions,the statistical data are dealt with areal interpolation methods using remote sensing as the ancillary data,and the statistical data of various irrigation regions are obtained.According to the principle of marginal revenue in economy,the marginal revenues of agriculture water for each of the irrigation regions are computed using the statistical data that are dealt with areal interpolation method,then we get the marginal revenue curves according to which we establish the water allocation model for the irrigation regions of the Yellow River Delta.This model gives a better solution to the water allocation of agriculture in the Yellow River Delta in the view of economic revenue maximum.
