基于能值法对林下经济的可持续发展分析--以林下种植为例

Analysis on Sustainable Development of Under Forest Economy Based on Energy Method:An Example of Planting under Forest

林下经济可持续发展是林下经济高质量发展的基础。论文基于能值分析法,构建能值分析评价表以及林下经济生态经济系统能值指标,对林农、林菌、林药三种模式六种类型的林下经济系统可持续发展能力进行量化分析。结果表明:三种林下经济发展模式对区域经济都有一定贡献,但系统独立发展能力较弱;林农模式能值投入大于产出且对环境造成压力较大,不可更新资源能值占比较高,属于资源消耗性发展模式;林菌模式合理利用区域资源,具有良好的可持续性;林药模式具有可持续性,但能值投入中自然资源能值较小,对当地资源利用不足。

Sustainable development of under forest economy is the basis of high-quality development of under forest economy.Based on energy analysis method,this paper constructs energy analysis evaluation table and energy index of under forest economic and eco-economic system,and makes quantitative analysis on the sustainable development ability of under forest economic system of three models of forest farmers,forest fungi and forest medicine.The results show that the three models all contribute to the regional economy,but the independent development ability of the system is weak;The energy input of forest farmer model is greater than the output,and causes great pressure on the environment.The energy of non renewable resources accounts for a relatively high proportion,which belongs to the resource consumption development model;The results show that the forest fungus model can make rational use of regional resources and has good sustainability;The forest medicine model is sustainable,but the energy of natural resources is small in energy input,and the local resources are underutilized.
