Research On Evolution Of Forestry Industry Niche Of Northeast State-Owned Forest Region

That aggressive development and utilization of natural forest resources, the single forest dependent industry structure, extensive and low value-added forest produce, makes the northeast state-owned forest region fall into the resource curse trap; causes the resource crisis, economic crisis and ecological crisis of state-owned forest region; causes the continuous entropy increase and survival dilemma of forestry industry of state-owned forest region. The objective situation of global climate change and international political game, the construction demand of modernization development pattern of "Five Progress", the developing requirement of green economy, cyclic economy and low-carbon economy reshaps the strategic position and mission of forestry development and forestry industry operating, promotes the constandly expand of characteristics, competitive and alternative industries of state-owned forest region; promotes the structure adjustment and function optimization of forestry industry in state-owned forest region; promotes coordinate achievement of economic, social and ecological benefits of forestry industry developing. The effective integration between natural science and social science, the reasonable comradeship between niche evolution and forestry industry evolution, which helps broaden the analysis sight of forestry industry evolution of state-owned forestry industry; helps grasp the essential nature and intrinsic mechanism of orestry industry evolution of state-owned forestry industry, helps constructure a higher suitable forestry industry niche, helps ptomote the positive and adapting evolution of forestry industry in northeast state-owned forest region.Based on the threshold analysis and positive analysis, the dissertation systemic applies documentation research, analogy analysis, system theory and model analysis, so as to solve the key problems of the research on evolution of forestry industry niche.Firstly, the dissertation defines the conception of forestry industry ecosystem and forestry industry niche, describes the systemic interaction between forestry enterprise niche and industry niche, establishs the ecolution paradigm of forestry industry niche from the angle of paradigm research.Secondly, the dissertation analyzes the multi-function, divertisy and affinity of enterprise species, and then distinguishes keystone species feature and advantageous position of state-owned forestry enterprise.Thirdly, the dissertation backup the industry niche ecostate-ecorole in the stage of establishment of tradition forest industry system, the stage of establishment of core enterprise of forest industry and the stage of construction of modern forest industry ecosystem, distinguishes the niche ecolution factors such as resource,demand, technology, policy and system using the situation awareness&visualization model, defines the guidance property and restraint property; ayalyzes the adaptable selection mechanism based on Lamarkism, natural selection mechanism based on Darwinism and niche construction mechanism, and ayalyzes cooperation of the evolution mechanisms.Fourthly, fundamental niche of forestry industry is the foundation of ecolution of realized niche, is the basis of establishment of suitability strategy of ecological unit; the dissertation selects the functional and structural fundamental niche through the entropy weighting model and dynamic control conflict model, selects the most desirable and suitable fundamental niche of forestry industry of ecology-symbiosis; the dissertation explains the hereditary evolution behavior, variation evolution behavior, acquired evolution behavior and cooperativity evolution behavior of realized niche of forestry industry based on the analysis foundation of ecolution mechanism of niche ecolution of forestry industry.Fifthly, the dissertation constructs the evolution paths of forestry industry niche, includes optimization of ecological unit of forestry industry, intervention of niche ecolution factor and suitability adjustment of forestry industry niche according to the feature, evolution factor, evolution mechanism, fundamental niche, evolution behavior of realized niche of forestry industry, so as to construct the forestry industry niche of ecology-symbiosis, to promote the positive and suitable evolution of forestry industry niche, to promote the healthful, stable and ordered development of forestry industry ecosystem in northeast state-owned forest region, to promote the modern forest development and modern forestry industry system construction of northeast state-owned forest region.
