摘要：在对吊罗山2块不同海拔高度的热带雨林样地乔木层树种的RA、RD、RF及IV分析的基础上,通过出现-不出现数据的方差比例、基于2×2联列表的种间联结分析和卡方(χ2)统计量检验,对其种间联结性进行研究,以揭示不同海拔高度热带雨林种间联结性之间的相互关系。结果表明:(1)在不同海拔高度热带雨林中,群落内所有树种间总体呈显著正联结;(2)对2块不同海拔高度热带雨林样地20种优势种190对种对进行χ2检验,发现种对间大都呈现无联结;(3)2个不同海拔高度热带雨林种间联结比例及强度变化表明,物种正负联结比例随着海拔高度的增加而增加,而无联结比例则随着海拔高度的增加而降低。
In order to assess the relationships of species interaction changes with the height of elevation, species association in the two different altitude tropical rainforests in Diaoluo Mountain of Hainan Island was studied. Several indices of the tree layer in the oak nuturd sewndary forests in Diaoluo region were analyzed, including relative aboundance（RA）, relative dominance（RD）, relative frequency（RF）, and important value（IV）, Based on 2 x2 contingency tales of species presence or absence data, statistical methods including analysis of species association and X2 test were applied. The results showed that： l）The test revealed that all tree species in different altitude tropical rainforests showed a significant pattern of positive association; 2）The proportion of species pairs showed no associations in different altitude tropical rainforests though X2 test on 20 species forming 190 species pairs; 3）The proportion of the no associations species in the lowdown rainforest was higher than the tropical mountain rainforests with the increase of the altitude and the proportion of the positive and negative association was lower than the tropical mountain rain forest with the increase of the altitude.
