摘要 | 杉木〔Cunninghamia lanceolata (Lamb.) HK.〕在广西各个自然区域都有广泛的栽培,本文利用群落分类的方法将广西的杉木林划分出3个群丛纲,2个群丛组,30个群丛。通过对这些群丛的外貌、结构和种类成分变化的研究,分析和确定其所处的演替阶段和演替趋向,为其合理经营提供科学依据。 |
Abstract | Cunninghamia lanceolata(Lamb.)HK.is an endemic well-known timber species with high quality in China. There is expansive cultivation in different geographical regions of Guangxi. Three association classes, two association groups and thirty associations were identified by the community classification methods. The successional stages and trends toward recovering of evergreen broadleaf forest were proved through analysis of the differences in community physiognomy, structure and species composition among these associations. The results, as a scientific base, are able to serve the management of these communities. |
