Analysis On Dynamic Changes And Driving Forces Of Forest Land In Guilin

As a world-renowned scenic and cultural city in China,Guilin is a bridge that connects the coastal areas of South China and the southwest in terms of economy.With the deepening of the construction of international tourist destinations and the implementation of industrial revitalization strategies,more and more large enterprises,high-quality projects,and high-end talents have settled in Guilin.In the process of sustained and rapid development of various economic and social undertakings,the contradiction between the demand for and protection of forest resources in Guilin has become increasingly prominent.In order to better protect the forest resources of Guilin,this study takes Guilin city as the research object,selects its four remote sensing images in 2005,2010,2015 and 2020 for random forest classification,analyzes the dynamic changes of land use types in the study period,and further analyzes the dynamic changes and driving forces of forest land in the study area.The main conclusions are as follows:1.During the research period,the speed of land use change in Guilin city showed a first increase and then a decrease,with a comprehensive land use dynamic value of 0.25%.Among them,the overall forest area decreased,and the changed forest land was mostly transformed between unused land and cultivated land.2.Using SPSS and geographic detectors to analyze the driving forces of the dynamic changes in forest land in Guilin during the research period,from the perspective of driving forces,the common influencing factors are elevation and annual average temperature,and the specific driving factors are the positive correlation between forest land area and elevation and slope,and there is a negative correlation with other selected driving factors.3.By analyzing the dynamic changes and driving forces of forest land in Guilin city,some suggestions are proposed: to continue afforestation to avoid the gradual reduction of forest land area.In terms of forest land construction and management,relevant management should consider the conversion of unused and arable land,and combine economic,terrain,human,weather and other factors,to achieve better management and protection of forest resources.
