近年来,淮河干流阻水障碍物越来越多,阻水问题日趋严重。与五十年代相比,正阳关以上减少泄量约2000秒立米,正阳关至蚌埠河段减少泄量约1500秒立米。水电部把淮河列为今年全国两条重点清障河道之一。淮河干流的阻水障碍是自六十年代以后加剧的。由于沿淮人口急剧增长,与水争地,盲目围垦河滩地,在河道内大量种植杞柳、芦苇、荻柴等阻水植物,修建各种阻水建筑物,从而降低了河道的泄洪能力。一九七二年国务
In recent years, there are more and more water blocking obstacles in the mainstream of the Huaihe River, and water blocking problems are becoming more and more serious. Compared with the 1950s, more than Zhengyangguan to reduce the discharge of about 2000 seconds Li meters, Zheng Yang Guan to Bengbu River to reduce the discharge of about 1500 seconds Li meters. The Ministry of Electricity and Water has listed the Huaihe River as one of two major riverbeds to be cleared off the country this year. Water blocking obstacles in the mainstream of the Huaihe River have intensified since the 1960s. Due to the rapid population growth along the Huaihe River and the water dispute, blind reclamation of floodplain sites and the construction of water-blocking plants such as willow, reed and Dictyophylla in large numbers in river courses have resulted in the construction of a variety of water-blocking structures, thus reducing flood discharge capacity in rivers. 1972 State affairs
