摘  要：
根据53块样方资料,对门头沟区煤矿废弃地自然恢复植被进行了TWINSPAN数量分类和DCA、DC-CA排序。结果显示:由TWINSPAN数量分类可将该区自然恢复植被划分为11个群落类型;以TWINSPAN数量分类为基础的DCA二维排序图将样方分为4个生态类型,反映了门头沟区煤矿废弃地植被自然恢复演替规律,即草本群落→灌丛群落→灌丛向乔木群落过渡→乔木群落;DCCA排序较好地揭示了该区自然恢复植被的分布格局与环境梯度的关系:第一排序轴表达了朝植被自然演替方向的一个综合梯度,第二轴主要表现出自然恢复植被的坡度、坡向的变化趋势,即水分和温度;DCA排序反映了群落在主要环境梯度上的分布,而DCCA排序进一步表明了群落与环境因子间的生态关系。

摘  要：
A study was conducted on quantitative classification and ordination of vegetation after natural restoration on abandoned mine land in Mentougou District,Beijing based on data from 53 quadrates using TWINSPAN,DCA and DCCA.Results showed that the natural vegetation in the abandoned land could be classified into 11 vegetation assemblages by TWINSPAN.The sample plots were divided into four ecotypes according to the DCA two-dimensional plots based on TWINSPAN,which indicates the natural succession rule for the vegetation,namely from herbaceous community to shrub community,then from shrub community to arboreal community,and then to arboreal community.The results of DCCA clearly reflect the relationships between the pattern of plant communities and natural restoration and environmental gradients.The first ordination axis in DCCA indicates the natural succession of vegetation gradients,and the second axis exhibits the changing tendency of slope gradient and aspect,namely moisture and temperature.The DCA ordination reflects the distribution of communities in the main environmental gradients,while the DCCA ordination further indicates the ecological relationships between the communities and environmental factors.
