| 摘 要： | 通过对吉林省前郭县乌兰图嘎林场固定沙丘植被试验区采取限制放牧与过度放牧的对比调查，结果得出，控制放牧有利于固定沙丘植被的恢复，可有效地提高草牧场植被的多样性和异质性；而过度放牧通常是吉林省西部草牧场退化的最重要原因。

| Abstract: | The comparation analysis was made between the controlled grazing and over grazing in the experimental area of fix dune in the Wulantuga Forest Farm, Qianguo County, Jilin Province. The result indicated that the controled grazing was favourable for the recovery of fix dune. It effectively improved the diversity and heterogeneity of the vegetation. The over grazing on the other hand, was the most improtant cause for the degeneration of grass land in western Jilin. |
