《国务院关于大力开展农田水利基本建设的决定》的颁布,给淮河流域的水利建设带来了多年未有的好形势。一些十多年来一直想治理、而未能得到治理的河道开工了,而且进展顺利,质量很好,并已发挥效益。地跨淮河流域四省的黑茨河、徐洪河、梁济运河等3条骨干河道的治理就充分说明了这一点。黑茨河原为沙颍河下游的一大支流,1980年茨淮新河通水后,改入茨淮新河,全长192公里,流域面积3007平方公里。本流域历史上曾受黄河洪水侵袭,大部分干支流被淤塞。50年代曾对干流进行了治理,但标准很低,因此,这里仍然长期受洪涝灾害的威胁。这一次黑茨河工程的治理从1989年6月正式开工。这 The promulgation of the “Decision of the State Council on Vigorously Launching the Capital Construction of Farmland and Water Conservancy” has brought the good situation that has not been enjoyed for many years to the water conservancy construction in the Huaihe River Basin. Some of the river courses that have been trying to govern for more than a decade and have not been able to get governed have started, and are well advanced, of good quality and have brought benefits. The management of three major river courses, such as Heihe River, Xuhong River and Liangji Canal across the four Huaihe River basins, fully illustrates this point. Heizi River was originally a major tributary of the Shaying River downstream. After the new Huaihe River passed through 1980, it was changed into the New Huaihe River with a total length of 192 kilometers and a drainage area of ​​3,007 square kilometers. The basin has historically been affected by the Yellow River flood, most of the tributaries were blocked. In the 1950s, the mainstream was governed but the standards were low, so there was still a long period of threat from flooding. This time the treatment of the Hetzhe River Project started in June 1989. This
