国有林区林下经济发展的生态位态势测度研究——以黑江省为例

On the Niche Ecostate-ecorole Estimate of Under-forest Economy Development of State Forestry Region——Taking Heilongjiang Province as an Example

通过建立林下经济发展的生态位态势测度指标体系,测度林下经济发展的相对态值和相对势值,分析黑龙江省国有林区林下经济发展的生态位演化趋势。结果表明：森林旅游和森林食品是黑龙江省国有林区林下经济的最适宜发展项目;黑龙江省国有林区林下经济发展整体呈现线性增长趋势,但林下养殖、北药、水果及干果业相对势值增长呈现稳定失衡状态;黑龙江省国有林区林下经济发展对林业产业结构调整、林户生活水平提升、林木资源修复和生态效益发挥促进性不断增强。

That establishes an index system of niche ecostete-ecorole estimate of under-forest economy develop- ing, estimates the relative value of niche ecostate and the niche ecorole of under-forest economy developing, ana- lyzes the tendency of niche evolution of under-forest economy of state-owned forestry region in Heilongjiang province. The results shows： Firstly, the forest tour and foodstuff are the optimal development projects of un- der-forest economy of state-owned forestry region in Heilongjiang province; secondly, the integral non-timber forest-based development emerges a linear growth in state-owned forestry region, but the relative value of niche ecorole of under-forest raising, north medicine, fruit and dried fruit shows unbalanced status; thirdly, it has a persis- tently strength for the under-forest economy to adjust the forestry industrial structure, improve the living standard of self-employed tree cultivator, restore the forest resource and exert its ecological benefit.
