Interspecific Association of Woody Plants in Michelia shiluensis Community, Diaoluoshan Nature Reserve, Hainan Province

Abstract

Abstract:

Michelia shiluensis is one of the endemic plants and national class II endangered protected species in Hainan Island. It has a sporadic distribution in central and southern mountains of Hainan Island, including Diaoluoshan Mountain, Yinggeling Mountainand, Wuzhi Mountain, etc. Diaoluoshan Nature Reserve is the most concentrated distribution area of M. Shiluensis. Study on the interspecific association of woody plants in M. shiluensis community in Diaoluoshan Nature Reserve and analysis of its status in the community is of great significance to in-situ conservation of the species. On the basis of a 2×2 contingency table, χ²-test, Pearson correlation coefficient test and Spearman rank correlation coefficient test were used to analyze the interspecific relationship between M. shiluensis and other plants in the community. There were more positive correlations in the shrub layer than in the tree layer. There was no significant interspecific association between M. shiluensis and most other plants in the community, the interspecific relationship showed a relatively loose trend in general, and the trend of mutual independence among populations was obvious. The tree layer and shrub layer were generally more positively associated with M. shiluensis, indicating that the development of the community was beneficial to the development of the M. shiluensis population.

Key words: Michelia shiluensis, interspecific association, community, Diaoluoshan Nature Reserve, Hainan province
