Experimental ecology research on destroyed evergreen broad-leaved forests in TNFP, Zhejiang (Ⅲ): Analysis the adaptive strategy of common species in evergreen broad-leaved forest from caloric value(Chinese)

摘要: 对浙江天童国家森林公园木荷+米槠群落中植物各器官的热值进行比较分析.结果表明,(1) 从生活型来看，不同生活型其叶的热值差异显著(df＝47，P0.05)，常绿阔叶乔木高于常绿阔叶灌木，落叶阔叶乔木高于常绿阔叶灌木; (2) 主要植物在幼苗时期各器官热值普遍较幼树、成株时期高，在幼苗时期通过极强的光能转化能力，用于主干的高度生长; (3) 石栎、米槠、栲树及苦槠的萌生植株和实生植株各器官的能量配置格局不同.Abstract: Caloric values of various organs of plant species from Schima superba + Castanopsis carlesii community in the subtropical evergreen broad-leaved forest in Tiantong National Forest Park(TNFP), Zhejiang Province were studied in this paper. The results showed that caloric values of different life-form's leaves had significant differences,and evergreen broad-leaved trees and deciduous broad-leaved trees were higher than evergreen broad-leaved shrubs. It also showed that caloric values of dominant plants at sapling stage were higher than those of young and adult. Lithocarpus glaber, Castanopsis carlesii, Castanopsis fargesii, Castanopsis sclerophylla and Myrica rubra, five main species, showed the different caloric pattern of different organs. It suggests that energy pattern is closely related to their adaptive strategy in the subtropical evergreen broad-leaved forest.
