摘 要:调查分析了上海外环绿带植物群落的邻体干扰指数,结果表明:外环林带林分内,植物个体大小与基株的胸径、邻体胸径、邻体距离、邻体冠幅相关。群落内个体之间存在着强烈的种内竞争,且种内、种间及与整个林分的邻体干扰指数强度都随着基株木个体的增大而下降。提出了应依据邻体指数对植物生长空间的最适宜范围、邻体干扰程度等进行量化,选出各类植物群落中邻体间的较适宜的生长空间,并与群落中单位面积株数值与群落冠幅总面积等密度因子结合,为进行必要的经营措施提供基础。Through the investigation of neighborhood interference index of plant community in Shanghai outer--ring greenbelt, the results showed that in the outer--ring forest belt, the plant size was related to the DBH of genet the DBH of neighbor, the neighbor distance and the crown breadth of neighbor. There was a strong intraspecific competition among individuals within the community, and the intensity of the adjacent disturbance index of the species and the whole stand decreased with the increase of the individual. On the basis of the appropriate range, we quantified the neighbor index growth space on plant adjacent interference degree, which was suitable for the growth of adjacent space between the various types of plant communities, and numerical and community in a unit area of plant and community area combined with the crown density factor. Thus we hoped to provide the basis for the necessary management measures.
