摘　　要： 应用中心点四分法对大屏障次生常绿阔叶林进行了调查,确定了在大屏障常绿阔叶林的最小取样点数.分析了常绿阔叶林的优势种、外貌以及群落的结构.结果表明,群落以小叶青冈Cyclobalanopsismyrsinaefolia和黄牛木Cratoxylumcochinchinense为优势种.群落终年常绿,板根现象不明显,但层间植物比较丰富,体现了一定的南亚热带季风常绿阔叶林特征.群落的结构比较简单,可明显地分为乔木层、灌木层和草本层.大屏障次生常绿阔叶林对于该地区具有重要的意义,要加强对其的保护,促进森林的进展演替. The secondary-evergreen broadleaved forest was surveyed by using point-quarter sampling method in Dapingzhang Forest Park, Dongguan. The least sampling point in this type of forest was determined. Twenty sampling points were clustered into four types. The dominant species and the ecological physiognomy and community structure of evergreen broadleaved forests were analyzed. The forest was dominated by Cyclobalanopsis myrsinaefolia and Cratoxylum cochinchinense, with an evergreen physiognomy. This community lacked large buttresses and wood megalianas. But epiphytes are rich, demonstrating some features of the south subtropical monsoon evergreen broadleaved forest. Structure of this community is simple, and it can be divided into three layers, namely tree , shrub and herb layers. The secondary-evergreen broadleaved forest was important to the development of Dapingzhang. The protection of such forest must be strengthened to facilitate its succession.
