摘要
大青沟残遗森林植物群落分布于科尔沁沙地，是一个非常特殊的森林群落类型。在野外调查的基础上，分析了其群落学特点，并分析了对群落整体功能有重要影响的３１个乔、灌木种类的种间联结性。结果表明，大青沟落叶阔叶林主要由具复叶、小叶和中叶的落叶大高位芽植物和中高位芽植物所组成。植物种类丰富，计有维管植物１０６科，３５９属，７０９种，约占整个内蒙古植物种数的三分之一。主要木本植物之间发生联结的情况较多，既有正联结，也有负联结。
Survived forest plant community in Daqinggou which is located in Keerqin sandy land is a special forest ecosystem. Based on field survey, characteristics of community were analyzed, species association of 31 tree and shrub species which have important impact on the whole function of the community were also analyzed. The results were as follows: The deciduous broad leaved forest consisted of deciduous large sized and middle sized phanerophytes with compound leaves, little sized leaves and middle sized leaves. The plant species was abundant, there were vascular plants of 106 families, 359 genera, 709 species, and made up 30 percent of the total species in Inner Mongolia.
