| 摘 要： | 基于方差分析、X∧2检验、Ochiai指数、Dice指数和Jaccard指数等系列技术，测定了重庆四面山次生灌丛12个主要种群间的总体相关性，各种对间联结显性和关联强度，结果表明：上述系列技术能有效地度量出多种对间的联结性，揭示出四面山次生灌丛群落中，除个别种对外，多数种群间的联结性不显，总体上趋于独立分布，这反映了次生灌丛群落处于演替前期的年轻性和不成熟性等特征。

| Abstract: | With the use of a series of techniques , the interspecif ic association among the 12 dominant populations from the secondary shrub of mountain Simian in Chongqing was quantitatively studied.The analysis of variance was used for the explanation of the overall association of all the species; x2 -test for the interpretation of the notebility and quality of interspecific assoc iation; while Ochiai index,Dice index and Jaccard index were used for the display of the relational grade to each species-pair. The result shows that the inters pecific association isn't obviously correlative in most of the species-pair and generally tend to be independently distributed,which indicates the youngness an d unmaturity of the secondary shrub who is in early successional stage. |
