In the course of development of human society, nature resources and environment necessary foundation is indispensable. Nature Reserve is the most representative of biodiversity and natural ecological environment protection areas. Among them, the forest ecosystem type accounting for the largest share in the number and nature reserve area is the most typical terrestrial and complex areas of biodiversity, the largest reservoir for carbon, and the basic human security to the social and economic development. Therefore, it is essential for us to carry on these nature reserves and sustainable research. Second, its collaboration and sustainable development also has some paradigm significance.This paper focuses on the synergy of these nature reserves and sustainability through a combination of theoretical and empirical research methods, based on the study of systems theory, ecological theory, and theory of sustainable development and on the analysis of the related background, relationship and conditions of forest ecosystem nature reserves realizing synergism and sustainable development, and puts forward a targeted, coordinated and sustainable operational and strategic choice evaluation system. The main research contents and paper results are as follows:1. In the paper, the home and abroad on nature reserves and forest ecosystems, the entropy in the application of natural ecosystems, and the status and trends of sustainable development of nature reserves and other aspects of collaborative research are analysed. And Analysis of the system structure, characteristics, geographic characteristics and coordination of resources and sustainable relationships and meaning of the forest ecosystem nature reserves are gave. Analyse the forest nature reserves and forest ecosystem ecology and socioeconomic system of self-organization. The causes and conditions of self-organized forest ecosystems produce the overall orderly movement, it is essential to maintain their species diversity and forest species, forest communities of the multilayer orderly institutions. The order parameter of the nature reserves system of forest ecosystems, forest ecosystems, and socioeconomic systems are posed.2. Analysis of the nature reserve forest ecosystem type composition of the system entropy and negative entropy flow and entropy flow is the biological significance of biotic and abiotic environment, biology and biological environment of synergy in the entropy flow; a clear system of protected areas determination of the boundary entropy, and entropy change of entropy source was identified; established protected areas of forest ecosystem changes in the state transition equation is entropy, and Dawei Mountain National Nature Reserve as an example of practical application, instructions from entropy change of perspective to monitor, control and sustainable collaborative nature reserve is feasible.3. From the perspective of entropy change in forest ecosystem nature reserves of the cooperative control mechanism, feedback, collaboration between species control, collaborative strategies, control parameters to determine the establishment of a coordinated control of forest ecosystems in the joint development of the Equation. The main conclusions are:forest communities is stable climax community, is a multispecies coexistence and the formation of a complex food chain, food web results. Ordered by its co individuals, populations, three levels of system-level community key control parameters, order parameters to maintain. These control parameters and the order parameter is mainly caused by changes in entropy flow elements together.4. Analysis of the nature reserves of forest ecosystems capacity of the environment, sustainability form mechanism of negative feedback mechanism of the state of forest ecosystems, carrying capacity, resource constraints and the relationship of sustainable development; dissipative structure established under the forest state model of ecosystem carrying capacity and sustainable development in the interests of the game model; proposed selection method of sustainable development programs. The main conclusions are as long as the degree of utilization does not exceed the environmental capacity, does not destroy the forest ecosystem to the formation of dissipative structures, the system will be able to obtain and maintain sustainability.5. This type of forest ecosystems that affect the nature reserve entropy changing strategic environment planning, forest engineering and extent of protected areas and sustainable co-presented three corresponding Evaluation System:strategic environmental planning Nature Reserve, socioeconomic development of biodiversity indicators for sustainable impact assessment system; Grain for Green Project Reserve surrounding communities follow-up evaluation index system of sustainable development capacity; collaborative forest ecosystem nature reserves and sustainability evaluation system, and the use of The first index system for evaluation of the empirical analysis. Proposed and discussed three strategies for sustainable development approach of effectively reduce the forest ecosystem nature reserves entropy forest ecosystems while promoting their social and economic systems,that nature reserves in the forest ecosystems surrounding communities to establish farmer co-operatives, ecological tourism industry cluster, management information systems.
