1 引黄灌区发展节水灌溉的措施1.1 进行节水技术改造,完善工程配套设施当前节水灌溉的薄弱环节主要是斗渠以下田间灌溉技术相对落后。50年代后期以来,我们长期实行的投资政策是:灌溉系统骨干部分由国家投资,斗渠以下、甚至支渠以下由群众负担,灌溉工程的投资预算,实际上是骨干工程预算,而田间部分只做一点简单的典型设计,且不计投入工程总投资。这种不对相当于骨干工程1～2倍的田间工程投资做必要的分析和统
1 The Yellow River Irrigation District Development of water-saving irrigation measures 1.1 water-saving technological transformation, improve engineering facilities The current weaknesses in water-saving irrigation is mainly the following ditch irrigation technology behind the field is relatively backward. Since the late 1950s, our long-term investment policy has been that the backbone of the irrigation system should be under the national investment and fighting channels, and even the following should be borne by the masses. The investment budget for irrigation projects is actually the backbone of the project budget. Simple typical design, not counting the total investment into the project. This is not the equivalent of 1 to 2 times the backbone of the field engineering investment necessary analysis and systems
