侗族聚居区森林资源可持续发展评价——以三江侗族自治县为例

Evaluation of Sustainable Development of Forest Resources in Dong Ethnic Area:Taking Sanjiang Dong Ethnic Autonomous County for Example

为了摸清三江侗族自治县森林资源的数量、质量、生态功能和可持续发展状态,从而有效保护、管理和利用森林资源,在森林资源规划设计调查的基础上,运用定性定量描述法、理论分析法、Delphi法、综合评分法等对三江县的森林资源进行了评价。结果表明,三江县森林资源处于弱持续状态;全县林地资源丰富,空间分布均匀,林地利用率高但生产力低,森林林龄结构不合理,林种结构失衡,人工纯林比例过高,森林生态功能中等。因此,应在政府政策引导下,调动侗族群众参与,充分发挥宗教和传统护林习俗等有利因素,使森林资源得到良好的保护与发展,极大提升森林资源质量和生态功能。

In order to understand the forest quantity,quality,ecological function and sustainable development state,and to provide basis for effective protection,management,and use of forest resources,the forest resources in Sanjiang Dong Ethnic Autonomous County were evaluated using the qualitative and quantitative description method,theory analysis,Delphi method and comprehensive evaluation method based on the investigation data.The results showed that the forest resources in Sanjiang Dong Ethnic Autonomous County were in a weak sustaining state.The forest land resource in this region was rich and distributed evenly and its utilization rate was high but the productivity was low.The age and type structure of forest was unreasonable.Most forests were artificial pure forest and the ecological function was medium.Therefore,making Dong people participate in forest protection with the help of the religious,traditional customs,and government activities was important for protecting the forest well and improving the forest quality and its ecological function.
