淠史杭工程自1959年受益以来,累计溉溉农田1.2亿亩,因溉溉而增产粮食171亿斤,经济效果显著。但淠史杭工程还遗留不少问题,主要是面上配套差,水资源浪费严重。为加快工程配套,提高溉溉效益,进一步促进农业生产的发展,我省向世界银行贷款,五年内要对六条干渠及其479.1万亩溉区进行配套,其任务是十分艰巨的。合肥市所属淠史杭溉区中的分支渠、斗渠、农渠基本上没有规划设计,因此笔者就如何搞好溉区配套的规划设计,提出几点浅见。
Since the benefit of the Shih-Hang project in 1959, a total of 120 million mu of irrigated farmland has been accumulated and 171 billion kg of grain have been produced due to irrigation and the economic effect has been remarkable. However, there are still many problems left over by the Shih-Hang project, mainly due to poor supporting facilities and serious waste of water resources. In order to speed up the construction of facilities, improve the efficiency of irrigation and further promote the development of agricultural production, our province loans the World Bank. It is an arduous task to support six major canals and its 4.791 million mu irrigated areas within five years. The branches, ditches and agricultural drains in the Shi-Hang irrigation area, which belong to Hefei, basically have no planning and design, so I made a few humble opinions on how to improve the planning and design of the irrigation district.
