长江和黄河对比可以看出,黄河流域的黄土层,还可以再流失几百年、几千年,而长江流域许多地方的土层,却再也经受不住冲刷了,大部分山坡,一场大雨之后,便是土净石出,地毁山光,问题十分严重。长江流域陕西省境内出现的土壤、耕地和川道危机,就是最有说服力的例证。治理长江流域,要有全局观点和群众观点,不仅要看到干流上的三峡高坝等骨干工程,更要看到面上日益严重的水土流失给广大群众和国民经济建设造成的灾难和危机。国家应该重视和加强长江流域的水土保持工作。
As can be seen from the comparison between the Yangtze River and the Yellow River, the loess layer in the Yellow River valley can be lost for hundreds of years and thousands of years. However, the soil layer in many parts of the Yangtze River basin can no longer withstand the scouring. Most of the hillsides, After the heavy rain, it is the earth net stone out, to destroy the mountain light, the problem is very serious. The most persuasive exemplification is the soil, cultivated land and Chuan Road crises that have emerged in the Shaanxi Province of the Yangtze River Basin. To govern the Yangtze River valley, we must have a holistic view and a mass viewpoint. We must not only see the backbone projects such as the Three Gorges Dam on the mainstream, but also the disasters and crises caused by the growing soil and water loss on the surface to the general public and the national economy. Countries should attach importance to and strengthen the work of soil and water conservation in the Yangtze River Basin.
