该文系统地对榆林地区农田灌溉和水利资源进行分析，指出该区水地的重点开发区在北六县，灌溉农田可发展到15万hm²，1 hm²产量到6 000 kg，粮田面积为10万hm²,即可产粮达6亿kg。南部丘陵区发展集水补灌农业，修水窖150万孔，可对15万hm²梯田进行补灌，其中10万hm²种粮食，使粮食产量提高到3 750 kg/hm²，可产粮3.75亿kg，全区共产粮9.75亿kg

Present Situation and Development Potential of Farmland Irrigation in Yulin Prefecture

Based on systematic analysis of the farmland irrigation and water conservancy resource in Yulin Prefecture, it is revealed that developed area of irrigated land is mainly located in Northern six counties of Yulin. Where irrigated land can be developed to 150 000 hm²,yield can be increased to 6 000 kg/hm² and 600 million kg grain can be produced from 100 000 hm² of farmlands.By means of construction of 150 000 water cellars in South,150 000 hm² of terrace lands can be additional watered. So that 375 million kg grain can be produced in 100 000 hm² of terrace farm.This is very important to ecological environmental construction for the area and promotion of westpart development.In order to protectivly and efficently utilize the water resources, some more irrigation works must be constructed,evaluation and supervisory systems of water resources must be organized.
