今年5月间,黄河水利委员会派往西北的8个水土保持查勘队,现在正在黄河流域的晋西、陕北、陇东、陇中与陇南黄土高原上,紧张地进行水土保持查勘工作。几千年来,西北黄土高原的人们长期地受着水土流失的灾害,过着非常贫穷的生活。陕北一带每次下雨,地都成了小沟;无定河流域的沟壑面积已占耕地面积50％。水土流失,肥土便逐年减少,收成逐年下降。
In May this year, the Yellow River Conservancy Commission dispatched eight soil and water conservation survey teams to the northwest, and is now conducting intense soil and water conservation surveys on the Loess Plateau in western Shanxi, northern Shaanxi, Longdong, Longzhong and Longnan of the Yellow River basin. For thousands of years, people in the Northwest Loess Plateau have been suffering from soil and water losses and living a very poor life. Every time it rains in northern Shaanxi, the area becomes a small ditch. The gully area in the Wudinghe River Basin accounts for 50% of the total cultivated area. Soil and water loss, soil fertility will be reduced year by year, harvest declined year by year.
