福建建瓯市万木林罗浮栲群落特征的研究

Study on the Phytocoenological Features of the Castanopsis Forest of Wanmulin in Fujian Province

万木林地处福建省建瓯市，森林保护完好，罗浮栲群落是其分布面积最大的一个群落，无样地法群落调查表明，群落建群种为罗浮栲、木荷和栲．该群落结构复杂，上层乔木高大，有较明显的板状根，林下更新苗中上层优势种类仍有较大数量，群落层外植物相当发达，林内尚残留有少量的针叶、落叶树种．万木林罗浮栲群落是在阳性的针、阔混交林基础上演替而来的稳定的气候项极群落，具有典型的中亚热带地带性特征．

The Castanopsis community is the largest one in Wanmulin located in Jianou, Fujian Province. The investigation on the community by plotless sampling method indiCates that its dominant species in the tree layer are Castanopsis fabri, Schima superba, Castanopsis fargesii. In this community, there is a complicated structure, very rich lians and epiphytes. Some larger trees have appearent buttresses. A number of trees which are dominant in the first sublayer are in the scrub layer. A few deciduous trees and conifers remain in the community. The Castanopsis community in Wanmulin is stable climatic climax. It successes and formes bassed on a mixed decidous-coniferous forest, and possesses typical mid-subtropical zonal features.
