中文摘要：

应用传统林分结构因子配合混交度、角尺度、大小比数和开敞度4个林分空间结构参数,分析了紫金山风景区内枫香风景林的空间结构特征。结果表明：枫香风景林物种多样性丰富,乔木层共出现22个树种,径级结构分布连续,群落垂直结构特征明显,可分为3个林层,林分平均混交度为0.593,处于强度混交状态;林分平均角尺度为0.515,属于随机分布;林分平均大小比数为0.498,有接近40%的林木处于优势状态;林分平均开敞度为0.301,林木生长空间基本充足。枫香种群和马尾松种群优势度明显,群落暂时处于相对稳定状态,但马尾松径级分布不连续,群落最终将演替为带有常绿成分的落叶阔叶混交林。

英文摘要：

With the traditional stand structure indexes, the spatial structure of scenic forest of Liquidamabar formosana was studied by the 4 spatial structure indexes of mingling, angle index, neighborhood comparison and opening degree in Nanjing Zijin Mountain. The results indicated that： The species diversity of scenic forest of L.formosana was rich, there were 22 stocks in tree layer, the DBH structure of community was continuous, and the vertical structure of stand might be divided into 3 layers. The average mingling of the stand was 0.593, showed that the mixed degree of the forest is high. The angle index was 0.515, indicated that the tree position in this stand was random distribution. The neighborhood comparison was 0.498, and there were nearly 40 % trees in the stand being dominant. The average opening degree was 0.301, displayed the growth space of most trees in the forest was sufficient. L.formosana population and P.massoniana population are dominant now, and the community is being in a relatively stable state. But the DBH structure of P.massoniana population is discontinuous, so when all of P.massoniana died, the stand will become deciduous broadleaved mixed forest with some evergreen-tree species.
