1基本情况近年来,随着区域经济的发展,在水资源日益紧缺的情况下,用水矛盾不断升级。合理利用水资源,提高水资源的利用率,发展节水灌溉已经成为缓解甘肃省永昌县清河灌区水资源紧缺矛盾的战略选择。在节水灌溉的供水、输水和配水3个环节找准突破口,而设备的机械化程度是节水灌溉取得高效的有效途径。21世纪,机械化在节水灌溉中的应用将一步发挥重大作用。2研究区域的地质情况2.1自然地理永昌县清河灌区位于永昌县城东北部,东靠民勤
1 Basic Information In recent years, with the development of regional economy, contradictions in water supply have been escalating under the increasingly scarce water resources. Rational use of water resources to improve the utilization of water resources, the development of water-saving irrigation has become a relief of water resources in Yongchang County, Gansu Province, the strategic choice of the contradiction between water resources. In the water-saving irrigation water supply, water distribution and distribution of water to identify the three breakthroughs, and the degree of mechanization of equipment is effective water-saving irrigation effective way. In the 21st century, the application of mechanization in water-saving irrigation will play a significant role in the future. 2 Geological Conditions of the Study Area 2.1 Natural Geography Qinghe Irrigation District of Yongchang County is located in the northeast of Yongchang County,
