安吉龙王山天然森林植被的研究

Studies on Natural Forest Vegetation of Longwang Mountain in Anji County

采用点-线结合法对安吉龙王山天然森林植被进行调查,以植物群落的生态外貌特征为基础,结合植被数量分类划分植被类型,共划分为5个植被型、4个群系组和14个群系。各植被型具明显的垂直分布规律:常绿阔叶林和暖性针阔混交林分布在海拔500m以下山地;常绿、落叶阔叶混交林分布在海拔500～800m的山谷;落叶阔叶林分布在海拔800(600)～1500m山地;温性针叶林分布在海拔1300～1450m山脊。各群系分布也具一定的规律。最后就开展对龙王山森林植被的保护、优良乡土树种的选择和林木良种繁育及不同海拔带造林试验等提出建议和看法。

The natural forest vegetation of Longwang mountain was surveyed by point-line composite method and divided into five vegetation types and fourteen formations according to appearance characteristics of plant community in combination with quantitative, classification. The distribution boundary for each vegetation type was defined as follow: (1) evergreen broadleayed mixed forest and warm coniferous and broadleaved mixed forest, distibuted below 500m; (2) deciduous and evergreen broadleaved mixed forest distributed from 500m to 800m; (3) deciduous broadleated forest distributud from 800m (600m on ridge) to 1500m; (4) temperate conifer forest distributed from 1 300m to 1 450m on riges. There were also distribution patterns for each formation. Finally, the suggestion and points of view were put forward on the protection of forest vegetation, the selection and breeding of good indigenous tree species and afforestation experiment of different altitude belts, etc.
