摘要:
对乌兰布和沙漠北缘内蒙古农业大学教学实习基地5年的植被数量变化分析，结果表明：天然植物群落虽然没有发生演替，但其波动的趋势是向着逆行方向进行的。其原因主要在于该地区人口增加之后开垦土地面积的增加和牲畜数量增加带来的放牧强度加大。该地是一个生态脆弱区，此区要进行农牧业生产，必须考虑生态阈值。必须此区域要进入可持续发展必须走科技的道路，必须有政策扶持。
Abstract:
Change of plant community in the north border of Ulanbh desert, the teaching base of Inner Mongolia Agricultural University, was analyzed.The results indicated that plant community succession has not happened.But it has a trend of degradation.The reason is that increasing area of new plow for the population and livestock increases has brought the stress of grazing.This area is a fragile zone in ecology which needs to be considered the ecological limit for agriculture and animal husbandry productions.If there is a long term development, there must be supported by technology.Also it needs to be supported by policy.
