Spatial Distribution Pattern of Dendrobenthamia japonica (DC.) Fang Population in Mulinzi National Nature Reserve
摘要
Abstract
The Dendrobenthamia japonica (DC.) Fang population, the dominant species of the forest dy-namics plot in Mulinzi National Nature Reserve of Hubei Province,was studied in this article. Its point pattern and pearson correlation with some environmental factors around it was researched and calculated. The results are as follows:This population obeys an aggregated distribution in meso-and micro-scale and its aggregation intensity fluctuates to a certain degree,but its spatial pattern changes from a random distri-bution to an regular distribution.The positive correlation property between the individuals declines with the age of the population, which leads to the declining of the aggregation intensity.What′s more,the bigger the age gap is,the more outstanding the negative correlation is. The spatial correlation between the Den-drobenthamia japonica (DC.) Fang population with the Carpinus fargesiana H. Winkl. population and the Sorbus folgneri ( Schneid.) Rehd. Population is positive and outsanding, while with the Cyclobalanopsis myrsinaefolia (Blume) Oerst. population is negative and outsanding.Finally,we also find that the distribu-tion of the Dendrobenthamia japonica (DC.) Fang population is influenced by some environmental factors including the elevation,the convexity,the gradient,the pH of soil,but not by the slope aspect.关键词
