李洪河流域位于我县南部,全流域包括四个公社,三十一个大队,控制面积一百七十平方公里。流域境内丘陵起伏,沟壑纵横,河道交错,有十三面坡,十一道粱,七条沙河滩,自然条件较差。解放前,这个地方河床不定,洪水横行,风沙遍地,植被稀少,水土流失十分严重“梁似和尚头,洪水如猛兽,遍地风沙飞,十年九不收”,这是昔日李洪河流域的真实写照。 Li Hong River basin is located in the southern part of our county, the basin includes four communes, thirty-one brigade, control area of ​​170 square kilometers. Basin hilly, gully aspect, river staggered, thirteen slope, eleven sorghum, seven sand beach, poor natural conditions. Before the liberation, this place had uncertain riverbed, rampant floods and sandstorms, scarce vegetation and very serious water and soil loss. “Like a monk head, the flood was a mighty beast. It flew over the earth and flew over nine decades.” This is a true portrayal of the Lihong River basin in the past.
