| 摘 要： | 采用反映聚集强度的6项指标对南京幕府山矿山废弃地自然恢复的构树(Broussonetia papyrifera)种群不同发育阶段的空间分布格局进行了研究，并用波谱分析方法研究了构树空间变化的规律。结果表明，幕府山矿山废弃地自然恢复的构树种群在不同发育阶段的空间分布格局均呈聚集分布，但随着生长发育的进程聚集强度逐级减弱，呈扩散性的趋势。波谱分析也表明构树种群在幼苗和幼树阶段其空间格局分布呈周期性的波动变化，大树阶段的空间分布格局没有周期性的变化。

| Abstract: | The spatial distribution patterns of Broussonetia papyrifera population in the growth stages which naturally revegetabled in mine spoils in Nanjing Mufu mountain were researched by six indices of contagion intensity and the active regulation of spatial distribution patterns of B.papyrifera population was analyzed on the basis of the spectral analysis.It indicated that the spatial distribution patterns of B.papyrifera population in the growth stages which naturally revegetabled in mine spoils in Nanjing Mufu mountain were contagion distribution,and the contagion intensity became weak and turned into a diffuse trend with its growth.It also indicated that the spatial distribution patterns of B.papyrifera population in the stages of seedling and young tree moved regularly based on the spectral analysis. |
