Results show 1 the total water requirement of the crops in the Jinghe Watershed is 740543.20×10^4 m^3, accounting for 41.58% of the total water requirement of the region; 2 of the two major groups of crops, grain crops are higher than cash crops in water requirement quotas; and among specific crops, vegetables, melons, rice and cotton are higher and sunflower, potato and benne are lower than other crops; 3 water requirement per hectare varies from county to county with the highest being 5682m^3hm^(-2), in Jingyang County, and the lowest 4022 m^3hm^(-2) in Dingbian County, averaged to 4 583 m^3hm^(-2), but the water requirement quota of a crop does not vary with the county, so calculation of water requirement quota of a county is closely related to its cropping structure; and 4 because of serious waste of water in farming, the actual water consumption in agriculture in the region is much higher than the calculated crop water requirement.

结果表明，泾河流域农作物需水量总计740543.20万立方公尺，农作物需水占总需水量的比例较高，为41.58%。粮食作物需水定额较经济作物高；就具体作物而言，菜、瓜类、水稻、棉花等需水定额较高，向日葵、薯类、胡麻等较低。各县单位面积需水量差异较大，平均值为4583立方公尺hm^(-2)；泾阳县最高，为5682立方公尺hm^(-2)，定边县最低，为4022立方公尺hm^(-2)。由于事先设定大多数作物的需水定额不随县的改变而改变，因此需水量与作物结构密切相关。农业用水浪费严重，使泾河流域农作物实际用水量远高于需水量的理论计算值。

Water-deficient is a key factor to restrict agricultural production and economic development in the region. In order to improving the infrastructure conditions of agricultural production as soon as possible, inducting farmers to develop non-pollution vegetable and economic crops, helping farmers to increase income in planting and breeding, and facilitating sustainable development of agricultural production, according to Year 2002 Project Guide Rural of Mini-type Water Commonweal Establishment Construction and some relative requirements, local government has defined to construct rainwater-collection model project in Tianhui brae after analyzing and reasoning.

水资源缺乏是制约该区域农业生产和经济发展的关键因素，为改善丘陵灌区农业生产条件，引导农户发展无公害蔬菜和经济作物，在种植和养殖业上帮助农户增收，促进农业生产的可持续发展，根据2002 年度农村小型水利公益设施建设项目指南和相关要求，经过认真研究，科学分析论证，确定在天回山丘陵区实施集雨节水灌溉示范项目。

It is projected that in 2000, the grain yield per capita will reach 400-424 kg or total yield of 500-530 million tons, with the development of cash crops, forestry, animal husbandry and fishery production, to make the caloricity from food to 2715 kcal/day per capita, protein 73.5 g and fat 56.6 g meeting the basic demand of normal human bodies.

计划到2000年人均粮食产量达400~424公斤，总产量达到5000~5300亿公斤的基础上，其它经济作物和林牧渔各业全面发展，使城乡居民每人每天从食物供给中的热量达到2715千卡、蛋白质73.5克，脂肪56.6克，可以基本上满足人体的正常需要。
