【摘要】 笔者对江西亚热带常绿阔叶林进行了广泛的实地考察,并对其有关的生态学特征进行了分析,得出如下结果: 1.外貌是由革质,单叶,小型叶为主的常绿中高位芽植物决定的; 2.具有明显的成层现象和复杂的层片结构。常绿高位芽植物层片占优势,也有少量落叶高位芽植物层片; 3.区系成分丰富而复杂,计有维管束植物110余科、370余属、2000余种,具有与澳洲、热带美洲、热带非洲、东南亚、北美所共有的植物区系100余属,与世界各地区联系广泛且密切; 4.种群多样性指数为2—4之间; 5.群落最小面积为900米~2,最少样点为12个; 6.群落类型多,被划分为7个群系组,26个群系。更多还原

【Abstract】 The evergreen broad-leaved forest is the climax vegetation in Jiangxi. Through widely investigating the vegetation in Jingangshan,Yunjushan.Lianhuashan, dagang-shan, Xinjian and Yongfeng, and then deeply analysing the ecoloical characteristicsof evergreen broad-leaved forest of subtropics in Jiangxi, the following conclusionscan be reached:1. Its physiognomy is characterized by the leathery simplele-aved microphyll-ous type of phanerophytes.2. In the community structure, there is a distinct stratification (i.e.arburous layer,scrub layer and herb layer). Synusia structure is considerablly complex. They are dominated by evergreen phanerophyte synusium.3. The floristic composition is complicated. There are more than 2000 species (110 family, 370 genera) of vascular plant.4. Population diversity indexes is about 2-4.5. The minimum area of evergreen broad-leaved forest community in Jiangxi is 900m2. The least sampling points of plotless method is 12.6. There are seven formation groups and 27 formations.更多还原
