薛城区农业综合开发中型灌区节水配套改造建设项目分两年完成,干、支渠全部实现防渗化处理,由此渠系水有效利用系数达到0.7。在此基础上对项目区分别按有项目和无项目,在50%与75%两个不同保证率下进行供需平衡分析。经水平衡分析粮经比例调整到5:5后,通过实施项目建设,发展节水灌溉,项目区水资源能够达到供需平衡,并且粮经比例调整到6:4依然满足要求,缓解供水紧张的局面。
Xuecheng District Comprehensive Development of Medium-sized Irrigation Water-saving irrigation and transformation projects completed in two years, dry and branch channels to achieve all the anti-seepage treatment, the canal water use efficiency factor of 0.7. On this basis, the project area shall be analyzed respectively with and without project according to the two different guaranteed rates of 50% and 75%. After the proportion of grain and food is adjusted to 5: 5 through water balance analysis, the water supply in the project area can reach the balance between supply and demand by implementing the project construction and developing water-saving irrigation, and the proportion of grain and food to 6: 4 still meets the requirements to ease the shortage of water supply situation.
