摘要： 本文利用二歧指示种分析法TWINSPAN将广西热带石灰岩季节雨林的30个样地划分两大类共6个群落：洼地季节雨林(1)火焰花+萍婆群落； (2)海南风吹楠+人面果群落，石山季节雨林(1)东京桐+广西顶果豆群落； (2)假肥牛树+安南牡荆群落；(3)肥牛树群落； (4)肥牛树+蚬木群落。文章还利用无偏对应分析法DCA对群落进行了排序，指出由洼地至山坡水分条件由湿到干是影响群落变化的主导因素。环境的封闭程度对群落变化也有一定影响。

Abstract: Thirty samples of tropical limestone forests in Guangxi were classified into six formations using Two-Way Indicator Species Analysis (TWINSPAN) and these six formations constitute two vegetation types of higher class. The classification results are: Ⅰ. Valley seasonal rain forest:( 1 ) Form. Saraca chinensis + Sterculia nobilis ( 2 ) Form. Horsfieldia hainanensis +Dracontomelon duperreanum. Ⅱ.Limestone hill seasonal forest: (1)Form. Deutzianthus tonkinensis + Acrocarpus fraxinifolius var. guangxiensis( 2 )Form. Cleistanthus petolottii + Vitex annamensis ( 3 ) Form. Cephalomappa sinensis ( 4 ) Form. Cephalomappa sinensis + Burretiodendron hsienmu. The samples were also ordinated using DCA (Detrend Correspondence Analysis) . The first axis of ordination reflected water gradient from wet valley to dry hill. The second axis was shade gradient.
