摘要
采用 2× 2列联表 ,通过x2 -检验、AC值、PC值及点相关系数 φ值对梅子湖风景区森林植被中出现频率较高的 17个种群的种间联结进行了定量分析 ,w -检验表明 ,梅子湖森林植被样地 17个常见种群的总体种间关联性呈显著正关联。梅子湖森林植被样地中 17个常见种的种间联结关系中 ,绝大多数种对呈正联结 ,少数种对呈负联结 ,但大多数种对间的联结关系未达到显著水平 ,种对间的联结性较松散 .
Based on the 2×2 contingency table, interspecific association among 17 common species forests of Meizi Lake area was examined by using various indices, the results are as follows:W-test indicated that positive correlations exist among the common populations;The most pairs of the populations in the forest communities in Meizi Lake area Showed positive correlations. The x2-test indicated that there were almost no significant interspecific association in most of the 136 species pairs, which reflects the independence of species pairs. The loose interspecific association is possibly related to the development stage of commiunities and ecological features of species. [
