Spatial Quantitative Analysis Of Spatial-temporal Evolution And Influencing Factors Of Provincial Forest Ecological Security In China

China is a country with abundant forest resources,and forest ecological security plays a crucial role in China’s sustainable development and ecological civilization construction.Nowadays,the change of ecological environment,the change of human life and the development of economy,has done a certain amount of damage to the forest ecosystem,the problem of forest ecological security caused by this has become increasingly prominent,which restricts the construction of ecological civilization.Therefore,how to improve the level of forest ecological security has become a very critical issue in forestry development and construction.Based on the research results of forest ecological security,this paper combines the theories of sustainable development,ecological carrying capacity and ecological compensation,and conducts an in-depth research on the development of the provincial forest ecological security in China.Firstly,the evaluation index system of forest ecological security was constructed based on DPSIR model,the comprehensive index method was used to evaluate the index,and the changes of the provincial forest ecological security in time and space were studied.Secondly,on the basis of the evaluation of the provincial forest ecological security,the global spatial autocorrelation analysis and local spatial autocorrelation analysis of the provincial forest ecological security were carried out,so as to better grasp the spatial correlation and clustering of the provincial forest ecological security.Then,the spatial error model is used to fit the forest ecological security and its influencing factors,and the influencing factors are analyzed according to the model estimation results.Finally,according to the results of the analysis,the paper puts forward some suggestions on the construction of forest ecological security from the aspects of government macro policies,protection zone construction and forest ecological construction,so as to promote the improvement of the level of the provincial forest ecological security in China.
