彰武县地处科尔沁沙地前沿,干旱和洪涝等自然灾害发生频繁,全县耕地面积1306.70 km~2,到2011年有效灌溉面积330km~2左右,自流灌区和井灌区节水程度不高,尤其传统灌溉渗漏量大,费水占地,灌水定额大,灌溉面积小,水利基础设施薄弱;因此,采取有力措施,大力发展节水灌溉工程建设,通过发展节水灌溉可有效利用水土资源,扩大发展水浇地面积;有效使用和保护水资源,防御自然灾害,发展高效节水型农业,促进农村经济持续稳定发展。
Zhangwu County is located in the frontier of Horqin Sandy Land where frequent natural disasters such as drought and floods occur. The area of cultivated land in the entire county is 1306.70 km ~ 2. By 2011, the effective irrigation area is about 330km ~ 2, and the water- In particular, traditional irrigation seeps large amount of water and covers an area with large fixed irrigation quota and has a small irrigation area and weak water infrastructure. Therefore, vigorous measures should be taken to develop water-saving irrigation projects and make effective use of water and soil resources through the development of water-saving irrigation , Expand the area for developing irrigated land, effectively use and protect water resources, prevent natural disasters, develop water-efficient agriculture and promote sustained and steady rural economic development.
