Résumé partiel
Desertification control is an important way to improve the ecological conditions in arid and semi-arid areas and maintain global sustainable development.The design and improvement of desert ecosystem compensation mechanism is of great significance to ensure the sustainable and stable supply of desert ecosystem services.To improve the ecological compensation in the process of"one size fits all"problem,at the same time as the desert system provide the scientific basis for the establishment of ecological compensation mechanism,this study selected arid and semi arid areas of different types of nature reserves,constructing a dynamic game model of desertification region ecological compensation of stakeholders,through accounting reserve the ecological protection of direct cost and opportunity cost,the quantitative evaluation of its natural assets value,arid or semi-arid grassland desertification in the exploration of ecological compensation standard.The main conclusions are as follows :(1)With Mitchell score method defines the stakeholders of reserve ecological compensation,based on the evolutionary game model to build,to related enterprises and farmers,reserve administration preferences according to their own interests in the process of game strategy choice and the stable equilibrium analysis,it is concluded that the introduction of the central government intervention in the process of ecological compensation,with the third party"constraint"mechanism as the guarantee,ecological compensation to reach a stable equilibrium ;in order to ensure the orderly progress of ecological compensation in the reserve,the principle of"who benefits will be compensated"should be adhering to,and the full amount of ecological compensation can fully mobilize the enthusiasm of farmers,herdsmen and enterprises to protect the ecological environment.(2)The value of ecological assets of the four reserves in 2018 is:Altun Mountain Nature Reserve(32.94 billion yuan)>Haba Lake Nature Reserve(5.65 billion yuan)>Anxi Extreme Dryland Desert Reserve(5.04 billion yuan)>Hatengtaohai Nature Reserve(2.03 billion yuan) ;The main source of ecological asset value of Altun Mountain,Haba Lake and Hatengtaohai Nature Reserve is ecosystem service asset value,which accounts for more than 70%.The main source of ecological resource value of Anxi Extreme Drought-Desert Nature Reserve is ecological resource asset value,which accounts for88.64%.The value of ecological assets per unit area of the Nature Reserve was as follows:Haba Lake Nature Reserve(65938.02 yuan/hm 2)>Hartengtaohai Nature Reserve(16525.31 yuan/hm 2)>Anxi Extreme Dryland Desert Reserve(8627.36 yuan/hm 2)>Altun Mountain Nature Reserve(7320.83 yuan/hm 2).
