废弃矿区植被恢复是现代生态学的一个重要研究领域，空间异质性是近年来用于研究植物群落的有效方法。本研究利用shiyomi的beta-二项分布方法对门头沟地区废弃矿区18种植物组成的群落进行对比分析。讨论矿区植被恢复随着时间的推移，群落异质性的变化。恢复时间愈长，种之间异质性越小。

It is a significant respect in restoration ecology to research plant restoration ecology of discard land in mining area. Spatial heterogeneity is an important index in ecology which is used to express the asymmetry and the complexity of the communities. In this paper, we use this index to find the characters of the vegetation distribution in the discard land in mining area of Mentougou district, Beijing, China. The data were statisticaly analyzed using the Shiyomi method, which is founded based on the beta-binomial distribution, and we obtain the result which is the different distribution of the species. Then we compare three mining area with diferent discarding-years. Vegetation in long-discarding-years mining area exhibits a lower spatial variance, and has a high stability index.
