摘要
在对缙云县生态公益林的林种、林龄、林分结构等现状分析的基础上,针对缙云县生态公益林以次生马尾松纯林为主的特点,进行了生态公益林改造目标和模式的比较选择,认为以马尾松为主的次生林开始的恢复和重建改造模式更切合缙云生态公益林资源特点和当地经济可持续发展的实际,并将缙云县生态公益林区分为松木林皆伐改造型、松木林择伐改造型、松木林择伐补阔改造型、松木林抚育改造补阔型、杉木改造型、封山育林型6种类型进行改造实践,效果明显。
Analysis was made on tree species,age and structure of ecological forest in Jinyun,Zhejiang province.The forest was dominated by secondary pure pine（Pinus massoniana）stand.Comparison on selection for transformation patterns and management target of current ecological forest showed that restoration and reconstruction of broad-leaf forest would be the best choice for sustainable development of local resources.Experiment was conducted on 6 transformation patterns,such as clear-cutting,selection cutting,selection cutting with planting broad-leaf trees,tending with planting broad-leaf trees,planting Cunninghamia lanceolata instead of pine,conservation for regeneration.
