| A consensus has been reached on the development of circular economy both at home and abroad.The eighteenth National Congress of CCP put forward clearly that promote resource conservation,develop recycling economy,increase forest coverage,and strengthen the construction of ecological civilization.Forestry is based on forest resources,which is in turn supported by solar energy.The conversion of energy in the ecosystem to material resources is sustainable and reflects the core of a circular economy because it produces no pollution and claims no investment of energy materials.Therefore,the research on the forestry’s circular economy and the optimization of its ecological industry chain has a very crucial significance.This thesis mainly comprises the following three aspects:Firstly,the paper analyzes the operation mode of our country’s forestry circular economy.It constructs the operation mode of forestry circular economy at microscopic,medium-scopic and macroscopic levels based on the principle of "5R",which is the starting point and foundation of the operation mode.Secondly,an analysis of the optimization of forest’s ecological industry chain has been focused.This is a practical study from industry and enterprise circular level.Based on the analysis of the operation mode of our country’s forestry circular economy and the optimization of forest’s ecological industry,this paper carries out a study on the optimized model of forest’s ecological industry.It proposes the viewpoint of the combination of the first,second and the third industry and a model of reticular industrial chain formation,which can be expanded transversely and vertically moves into a closed circuit circular mode.As a practical application on the optimization of the forest’s industry chain model,this paper describes the operation mode of a circular economy by taking wooden flooring as an example,that is,how a closed industrial chain has been formed from forest resources to recycling of flooring.In order to test the feasibility of development structure model,the paper constructs a system of the evaluation indexes of the wooden flooring industry chain.A case study of a stock-market-listed flooring company is also provided.The relations between forestry economic development and the climate are expounded in the third part.This exploration belongs to the optimized analysis.It explores the operation mode of a circular forestry industry against economic,social and environmental factors employing Granger causality test,Copula function model and C-D function model.The innovation of this thesis is embodied in the following three aspects:First,this paper constructs the operation mode of forestry circular economy at microscopic,medium-scopic and macroscopic levels based on the principle of "5R".Second,guided by the operation mode of forestry circular economy,this paper constructs the development structure model based on the redefined target and the developed investigation factors,thus riches the research content.In order to test the feasibility of development structure model,the paper constructs a system of the evaluation indexes of the wooden flooring industry chain.A case study of a stock-market-listed flooring company is also provided.Third,to expand the research vision,this paper arrives at some valuable conclusions on the relationship between forestry economic development and climate by exploiting Granger causality test,Copula function model and the extended C-D function model.The findings will provide reference for the establishment of macro economic development plan and forest resources development strategies. |
