一、目前东北地区一些主要城市的防洪标准均较低,如松花江沿岸的哈尔滨、齐齐哈尔、佳木斯等市分别只能防御解放以来出现过的1957、1959和1960年洪水,防洪标准只有30～40年。长春市位于新立城水库下游,城市防洪也只按100年一遇洪水设防,目前问题还很多。锦州市只能防御1963年出现的大洪水。大伙房水库下游的抚顺市、沈阳市防洪标准也分别达到100年和300年。本溪市目前左岸局部地段只有10年一遇洪水标准。
First, at present, flood control standards for some major cities in northeast China are relatively low. For instance, Harbin, Qiqihar and Jiamusi along the Songhua River can only prevent the 1957, 1959 and 1960 floods since liberation, respectively, and flood control standards are only 30-40 year. Changchun City is located in the lower reaches of Xinli City Reservoir, urban flood control floods only once a case of 100 years, the problem is still a lot. Jinzhou City can only defensive floods in 1963. Fushun City, downstream of Dahuofang Reservoir, Shenyang flood control standards were 100 and 300 years respectively. Benxi City, on the left bank at present only 10 years once the flood zone standards.
