摘要
传统看法认为;黄土高原水土流失严重,生态条件严酷,粮食自给困难.本文作者经过分析后认为:黄土高原粮食可以实现自给,而且可以和退耕还林还草搞好水土保持同步进行.
Traditional views held that it was difficult to realize self-support of grains because of soil loss and adverse ecological conditions there on the Loess Plateau. But some people who have been conducting research and production practice on the Loess Plateau think that the precipitation of 400 to 600 mm per year and the deep thick loess soil provide the necessary conditions for great increase of grains, and that increased inputs and intensive fanning are effective ways to increase grain production. Self-support of grains could be realized on the Loess Plateau, and this process can be carried on at the same time when soil conservation work is being done by returning some farmland into trees and grasses planting land.
