Research On The Model And The Supporting System Of Developing Circular Economy In Forest Region

On the background of human being do their best to seek the growth of economy,energy crisis and enviroment deterioration become the bottleneck of development,so circular economy arise.When human being work hard to change the using way of resource because of fossil energy's exhaustion,forest which had changed the earth and will effect its future comes into be paid highly attention.The goal of sustainable management and the three duties of protecting eco-enviroment,quickening economy development and prompting society advance, which make forest must take on the responsibility of connecting the future and the fate of human being.All of the above demand forest region accepting the idea of developing circular economy and putting it into play quickly.The important contents of developing circular economy is building the development model and the necessory supportting system in forest region.All the problems to be solved is the first premise to build circular economy in forest region in the end.Using the theory research and the society experience of foreign country for reference, combining with the research and practice of our country in recently years,directing with the characters and demand of forest region in our country,the dissertation raised up the content,the thinking way and the metholds,and the concrete practising model,supportting system and appraisal metholds of developing circular economy in forest region. On the base of sustainable development theory,econology theory and region-economics theory,reseached to develop circular econmomy in forest region from the time dimension, fators dimension and space dimension.Contrasting the pricinples of circular economy with sustainable development,researched the essentialrelation between them,found the theory origin of developing circular economy in forest region,at the same time developed' and richened S theory.Not only follow the ecology theory in material circular and building circular chains,but also raise up to follow the thoery in organizaton building of support system.Design the space arrangement and the key development point using the balance development theory and non-balance development theory of region-economics theory.Used the theory of taking human as the foundation in all of the sectors design and all the course of support system construction.According to the key point of forestry construction strategies,such as ecology construction,modern forestry constrruction,forest industry construction,forestry key project practise and type change of resource-based city,researched the chance of developing circular economy in forest region.Raised up the demand of the times,history chance and inner motive force of developing circular economy in forest region. Thought that the remote geographical position not only making develop circular economy more difficulty but giving some convenience in the direction of operating in relative independent region.The more importance is the decrease-resource using which make forest region still has relative rich resource and varied but allover industries because of remote geogripgical position.But all of them make it feasibilty develop circular economy in forest region.Raised up"5+3"model of developing circular economy in forest region.Design the model frome 5 direction to develop circular economy in forest region:①Design the model according to different administrative level(scale) to develop circular economy in forest region;②Design the multistage ecological chain model which take the lead industry as the core between different industries——ecological industry park——to develop circular economy in forest region;③Design the model of residues network take the residues as the core to develop circular economy in forest region;④Design the model according to type change of resourcebased city to develop circular economy in forest region;⑤Design the model according to rebuilding of northeast old industry base to develop circular economy in forest region.Design the circular economy in forest region from 3 administrative level(scale):①Design the small circular model take family(forest farm)as the core;②Design the middle circular model take tapical business as the core;③Design the big circular model in the range of forest region.They have intersect each other and have special emphasis itself.And specially point out to follow the principle of"holding capacity principle"in building the circular economy in forest region.The suitable and healthy support system is the necessory factors to develop circular economy in forest region.Firstly deman the people must change the traditional modes of thought,competely change in the development view,resource view,value view,consumption view and so on.Secondly raise up the level of science and technology,build and perfect legal system,lay down scientific and suitable ecouraged policies.Thirdly embody rational returning of forest resource price.Fourthly the support embody in design form,though the content has the speciality of develop circular economy in forest region,ecological industry park is the typical form to develop circular economy at the level of forest region.Beacause the result appraisal has fuzzy characters to develop circular economy in forest region,the dissertation use fuzzy maths connect with AHP methold to appraise it.Deal with the necessory of the fact of forest region and the development of circular economy,according to the advice of expert,choise the appraisal index,and appraise it qualitatively and quatitively. Further took Yichun forest region as the example analyse the result and gived corresponding appraisal.
