基于GIS的煤矿区农用机井依赖度的计算与分析

The analysis and calculation about the dependence degree of agricultural Motor-pumped well in the coal mining area based on GIS

中国北方水资源日益紧缺,作为重要的农田水利基础设施,农用机井对灌溉农业发展的作用越来越大。本文通过对南屯煤矿区机井作用的研究,定量分析各种土地利用类型受机井的影响程度,提出了机井依赖度的概念和计算方法。根据研究区各种土地利用类型对机井的依赖度和机井缓冲区的影响范围,对本区机井的建设和布局提出了建设性的意见,对其他区域的机井建设也有参考价值。

With the decreasing of water available in northern China, the agricultural motor-pumped well becomes more and more important for agricultural production. This paper quantitatively analyzed the affection degree of motor-pumped wells to various land-using types by studying the function of motor-pumped wells in the studying area, and put forward the conception of the dependence degree of Motor-pumped well （DDMPW） and the calculating method. Based on the dependence degree of motor-pumped wells of various land-using types and the affecting scope of the buffer of motor-pumped wells, the paper proposed some constructive suggestions for the building and arrangement of motor-pumped wells in the studying area, which was also valuable in consultation for the construction of motor-pumped wells in the other areas.
