天童几种常绿阔叶林优势种在砍伐后萌枝更新的初步研究

对以萌生方式形成的木荷、石栎、苦槠、栲树、米槠植株的根桩和萌枝状况进行了调查及测量。结果显示各种类萌枝数的大小顺序是:木荷>苦槠>石栎>米槠>栲树;结合萌枝状况可以推断萌枝能力的大小顺序应该是:木荷>苦槠>石栎>栲树>米槠。砍伐对木荷、石栎、苦槠、栲树、米槠萌芽更新都会造成影响,对栲树、米槠影响更大,而对木荷、石栎、苦槠影响较小。从植物萌生角度来说,这是形成研究地区大面积的以木荷、石栎、苦槠为优势种组成的次生灌丛的主要原因。

Primary Study on Sprout Regeneration of Several Dominant Species of Evergreen Broad Leaved Forest after Logging in Tiantong

The stump and resprouting of Schima superba, Lithocarpus glaber, Castanopsis sclerophylla, Castanopsis carlesii , and Castanopsis fargesii that fully grown from sprouting were investigated and measured. The results indicated that the orders of resprouting number are as follows: Schima superba>Lithocarpus glaber>Castanopsis sclerophylla>Castanopsis carlesii>Castanopsis fargesii . Moreover, it can conclude that the orders of the resprouting ability are as follows: Schima superba>Lithocarpus glaber>Castanopsis sclerophylla>Castanopsis fargesii>Castanopsis carlesii . The authors proposed that the resprouting ability on cutting of Castanopsis fargesii and Castanopsis carlesii more than Schima superba, Lithocarpus glaber and Castanopsis sclerophylla . In the plant sprout view, consequently , it is a reason that there is a great lot of secondary shrub, which dominated by Schima superba, Lithocarpus glaber and Castanopsis sclerophylla .
