Abstract

Abstract:

Chunia bucklandioides has been listed in key protected wild plants of national importance Class II,with a small population and narrow distribution.Studying the population characteristics and distribution of Chunia bucklandioides is of great significance for protecting the ecological environment and realizing the sustainable development of this species.The present research was conducted with Chunia bucklandioides in the Jianfengling area of Hainan Tropical Rainforest National Park.The diameter class was used to represent age class,and Chunia bucklandioides forest were divided into four age classes(I,II,III,IV).The pairwise correlation function g(r) was used to analyze the spatial distribution and correlation of different age classes of Chunia bucklandioides.The results showed that:1)The population of Chunia bucklandioides showed a pseudo-stable increasing trend,which could only survive but hard to expand its population size;2)The population of Chunia bucklandioides showed aggregated distribution at the small scale,and as the scale increased,the most of population developed into evenly distribution,while others showed random or aggregated;3)Individuals in different age classes were all aggregated at the small scale,and individuals in Class I and Class II showed a greater aggregation degree than others.As the scale increased,some age classes showed regular distribution and eventually evolved into random distribution;4)The germination and regeneration of Chunia bucklandioides mainly relied on individuals of Class III and Class IV,and the dependence of germinating individuals on the mother tree was Ⅱ>Ⅰ>Ⅲ>Ⅳ.Therefore,in the future,the main focus of conserving of the Chunia bucklandioides population should be on protecting the mother tree,appropriately intercutting budding seedlings around the mother tree and removing small plants near the budding seedlings of fallen branches.Additionally,live seedlings should be relocated for conservation as a means of expanding and conserving the wild population of Chunia bucklandioides.

Key words: Chunia bucklandioides, sprouting, population structure, spatial distribution patterns, spatial correlation
