Community characteristics of Cyclobalanopsis chungii forest in Mingqing nature reserve
摘要
Abstract
Cyclobalanopsis chungii forest in Huangzhulin nature reserve district in Mingqing of Fujian Province was selected to be researched. The community structure, species composition, succession direction, population age structure of C. chungii of its dominant trees and distribution pattern were studied by successive sampling method. The results showed that the stand level of C. chungii was obvious, the order of species richness and diversity index was as follows: herb layer ＞shrub layer ＞ tree layer. The order of uniformity index was as follows: shrub layer ＞ herb layer ＞ tree layer. The important value of C. chungii in community was the highest,but the seedling trees of C. chungii were rare; C. chungii population occupied an important position, and the frequencies in the succession layers and renewallayer were respectively 0.08 and 0.25; the population age structure of C. chungii showed a spindle type,the number of medium-sized trees was up to 842 hm-2, the number of saplings and big trees was small; young, middle-age and adult age individuals all showed aggregated distribution, which suggested C. chungii populations updated slowly with declining trend.关键词
