安徽省淮南市地处淮河中游,淮河纵贯全境,总长达87公里。沿岸的城镇、工矿、农业及其他国民经济各部门均靠淮河供水或进行物资交流。由于过去长期管理不善,除了行蓄洪区的行洪堤、生产圩超过标准外,沿岸建起了各种阻t水房屋、码头,河滩地违章堆放着砂、石、煤炭、煤矸石等人为障碍;以及滋生着树木、芦苇等各种天然阻水障碍。这些阻水障碍的存在,使淮南市境内的洪水位逐年提高而洪水泄量逐年减少。这不仅影响该市的防洪安全,而且威胁着整个淮河中游的防洪全局,遂使淮南市成为淮河中游阻水最严重的“卡脖子”地段之一。
Huainan City, Anhui Province is located in the middle reaches of the Huaihe River, Huaihe River runs through the whole territory, a total length of 87 km. Coastal cities, mining, agriculture and other sectors of the national economy rely on the Huaihe River for water supply or material exchange. Due to the poor management in the past, apart from the flood embankment in the flood storage area and the production levitation exceeded the standard, various kinds of houses, wharves and floodplains have been built along the coast to illegally pile sand, stone, coal and coal gangue, etc. Obstacles; and breeds a variety of natural water blocking obstacles such as trees and reeds. The existence of these water blocking obstacles makes the flood level in Huainan City increase year by year and the flood discharge volume decreases year by year. This not only affects the city’s flood control safety, but also threatens the whole flood control in the middle reaches of the Huaihe River. As a result, Huainan City has become one of the most “stuck” areas in the middle reaches of the Huaihe River.
