    摘要:

    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。

    Abstract:

    Comparing the deposit of Yellow river with Yangtze, we may see thatin the cathment area of Yellow river which is well known by its high de-posit, there is much loess to bear eroding for hundreds of years, and while in Yangtze valley,many places the soil layer is too thin to bear anyeroding. After a hard rain,most slope area become rocky land which can-not be used any more. The facts of soil crises, land crises and channelcrises are the convinced examples. To harness Yangtze valley, the overalland mass point of view must be taken, and main energy cannot only beput on the large projects in major channel such as Three Gorges Dam,butalso on the controlling the increasing loss soil and water which has brou-ght disaster and crises to mass and national economic construction. Weappear that the government should pay more attention to and strenghtenon the work of soil and water conservation in Yangtze valley.
