小清河是山东省一条重要的大型河道,也是济南市区唯一排水泄洪出路,境内河长70.5km。河道以南流域面积较大且为山丘区,支流众多,源短流急,每遇暴雨,常因排水不畅,造成支流下游及小清河干流两侧滞洪受淹,甚至堤防决口,泛滥成灾。仅解放后就发生过4次较大洪水,其中,1987年8月26日济南市遭受特大暴雨袭击,直接经济损失5.1亿元。 Xiaoqing River is an important large-scale river in Shandong Province and the only drainage outlet in Jinan City. The river is 70.5km long. In the south of the river, the river basin is large in area and is a hillock area with many tributaries and short source short streams. Due to poor rainfall, the drainage is often sluggish due to poor drainage, resulting in flood flooding on both sides of the mainstream of the tributaries and the Xiaoqing River, disaster. Only four major floods occurred after the liberation. Among them, the Jinan City was hit by a heavy rainstorm on August 26, 1987, with a direct economic loss of 510 million yuan.
