摘要
1 前言东北羊草草原一些地带,碱斑正以相当大的速度在不断地扩大发展,单位面积上的产草量受其影响逐年减少。目前碱斑的增长已成为畜牧业发展的一个障碍性问题。许多学者对碱斑的发生、发展做了大量的研究工作,祝廷成(1960年)全面分析了碱斑的发生及其利用;王明仁(1964年)研究了碱斑植被演替;吉林师大草原研究室(1961年)探讨了东北草原上的碱斑及其利用;徐任翔(1980年)
In the course of the preliminary degeneration,the alkali stain is an important stage.Uhich is also inevitavle in the succession of the praire vegetation in some areas of China.It has rhe evolution law of it's own:It undergoes the process of occuriug, developing and declining,falling.The effect ofhuman being is an important factor which both accelerates the process of occuring and developing of alkali stain and delays the course of recovering of the vegetation of the alkali stain.
