摘要
内蒙古草地资源丰富,但面临着逐年退化、面积日益缩小的危机,其中草原过度放牧是重要原因之一。本文基于内蒙古草原面积过百万(公顷)的31个旗县的数据测算了全区草原过牧的程度,结果表明,内蒙古草原过牧率高居70%左右,而且过牧程度由轻度转向中度。最后本文对内蒙古草原过牧的原因进行了深入分析,并提出了相应的对策建议。
The grassland resources in Inner Mongolia are fairly rich. But grasslands are fast being depleted and degraded now. Overgrazing is one of essential reasons .Based on the data of 31 pastoral banners which cover grasslands more than one million hectares, the extent of overgrazing in Inner Mongolia was calculated. The conclusion surmised that the rate of overgrazing in Inner Mongolia has reached 70 percent, and the level of overgrazing has changed light to moderate. An analysis was done to find out the reasons causing overgrazing. Measures to solve the overgrazing problem are provided below.
