摘要 本研究在对北京西郊九龙山地区植被(以次生灌丛和灌草丛为主)全面调查的基础上,分析了该地区的植物区系和植物群落特性。采用系统聚类的方法,以各样方包含的主要植物种类为属性,对120个样方进行了系统聚类分析,阐明了一定地段上的植物种类组成对生境条件(尤其是土壤条件)的指示意义。进而对九龙山植被及其生境进行了分类,并指出了各植物群落类型的组成、结构和分布规律及其与土壤厚度、土壤水分状况等生境条件的密切关系。文章还讨论了京郊低山地各生境类型的改造和利用途径。 In this paper, the secondary vegetation (mainly shrubs and herbs)andits indicative significance to the habitat in Joulong mountain area locatedin the western suburb of Beijing were studied. Based on 120 vegetation sa-mples, the system cluster method was used to group them by different si-milarity levels and the whole mountain area was divided into 4 major ha-bitat types. Furthermore, the vegetation was classified into 8 associationgroups or 13 associations. The indicative significance of each associationto its habitat, especially to the edaphic conditions such as soil moisture,thickness of soil etc., were pointed out. How to use the secondary shru-bs and herbs as indicators in assessing the forestry poteintial of the defo-rested land in the low-mountain area near Beijing was discussed.
