中文摘要	针对黄土高原地区水资源的不合理利用而引发的一系列环境问题，水资源环境恶劣．农业生产条件受限，制约农业持续发展；人们的思想观念比较传统、陈旧、固守、落后，小规模经营;科学技术落后、信息不畅，区位劣势;生存环境失衡．水土流失严重，自然灾害频繁．作物产量低而不稳的现状，分析了节水灌溉和作物产量的关系，多角度探讨了地面节水灌溉、地上节水灌溉、地下节水灌溉三种不同形式，根据黄土高原水土流失区的实际情况，对早作农业补充灌溉进行了研究。通过实地调查可知：节水灌溉已成为发展两高一优农业的有效途径和粮食再上新台阶的重要战略措施。
英文摘要	Unreasonable use of water resources has led to a series environment problems,such as water resources environment goes on worse, agricultural conditions are limited and agricultural development is restricted, the people＇s thought are traditional ,backward ,and conservative ,agriculture production is in small scale, technique is backward,information can not be transmitted well ,the area is in a disadvantage position,living environment is in the state of unbalance,soil erosion is serious, natural disasters occur frequently, the crop yield is low and unstable. After analyzing the relation between water-saving irrigation and crop yield,the three forms of water-saving irrigation on the ground,above the ground and underground are discussed with multi-angles. With the spot investigation,water-saving irrigation has become an effective method to develop agriculture and increase crop yield.
