南岭国家级自然保护区不同保护条件下优势种群的种间联结性分析
Interspecific Associations of Dominant Plant Populations Under Different Protection Regimes in Nanling National Nature Reserve, Guangdong Province
摘要
Abstract
A series of techniques including the analysis of variance, x2 test, association coefficient ( AC ) and Jaccard coefficient (or probability of co-occurrence, PC) were measured based on the 2 × 2 contingency table in order to analyze the interspecific associations of dominant plant species in three communities under different protection regimes in Nanling National Nature Reserve, Guangdong Province. The resuits indicated that the overall association of all species showed no significantly negative correlation in community I located at the experimental area,no correlation in community Il located at the buffer area and a significantly positive correlation in community Ⅲ located at the core area. There were 3-paired significant negative correlations in community I , l-paired significant positive correlation in three communities,respectively. With the transition from community I to community Ⅲ, the probability of co-occurrence (PC) increased and AC changed from negative to positive.关键词
