The Variation Of Forest Land Utilization In Shenchi Based On 3S And The Analysis Of Driving Force

Forest land is a kind of land-use methods.Research on the changes in i ts utilization is an important step to promote the optimization and integration of forest land resource structure,and it is also an important measure to im prove land use quality.With the economic development and population increa se,the contradiction between people and land has become increasingly promi nent.There is a problem of waste of resources,chaotic structure,and unreas onable allocation of land use.The same is true for forest land resources.The se problems have seriously hampered the sustainable development of human s ociety.Therefore,the purpose of this paper is to improve the efficiency of l and use,alleviate the contradiction between people and land,and promote th e sustainable development of society.This article is based on field surveys and interviews with relevant perso nnel,based on the human-land relationship theory,LUCC theory,and system theory,using RS,GIS,and ENVI software as technical support,and Shenchi County,Shanxi Province as the research object,and the use of forest land.The characteristics of change,spatial variation,degree of change,and the int ernal structure of the forestland are analyzed.Based on the analysis results,we further proceed from both natural and humanistic perspectives,and use a combination of quantitative analysis and qualitative analysis to explore and study the driving forces of regional forestland use changes.Through the prof ound analysis of the driving forces of forest land use change in the study ar ea,the paper proposes the feasibility study on the optimization of forest lan d use structure and healthy development of forest lands,and studies the development of regional forestry,management of forest land resources,adjustment of forest land structure,establishment of forest management plan,and The f ormulation and implementation of other economic policies provide a theoretic al basis and contribute to the ecological environment protection and coordinat ed human-environment development in Shenchi County.The innovation of the article is to study the change of forestland from two aspects: the overall ch ange characteristics of forestland and the characteristics of internal structure changes.The main conclusions of this study include:(1)In the decade of 2005-2015,the total area of forest land has increased,with a smaller increase,and t he rate of increase has been slow compared with other types of land,but th e ranking of forest land area in each category is determined by Three people rose to the second place;the mutual transformation of woodland and other land types occurred in the three major mountainous regions,and the distribut ion patterns were mostly strips or sporadic masses,or even punctiform.The most active transitions with forest lands were In terms of arable land andgra ssland,the conversion of grassland to forest land is mainly the conversionof forest land to arable land;during the study,the depth and breadth of theover all use of forest land have been deepened,with the increase in the breadth and depth of previous use,and the later period.There was a slight decrease in the breadth and depth of use;the internal structure of forest land change d greatly,and the proportion of three kinds of forest land changed drastically.The proportion of the other four types of forest land changed less andwas r elatively stable,and the development potential of suitable forest land was hu ge.(2)Quantitative analysis shows that both natural and human factors have an impact on the forest area change in Shenchi County,but human factors have the greatest impact on the change of forest land area.Rural population and sunshine duration were negatively correlated with forest land area.Afforestation area,per capita GDP,primary industry output value,gross valueof pr oduction,average annual precipitation,per capita disposable income of reside nts and forest land area were positively correlated.Relevance from strong to weak is ranked as follows: afforestation area,per capita GDP,primaryindust ry output value,gross production value,rural population,average annualpreci pitation,per capita disposable income of residents,and sunshine hours.Throu gh qualitative analysis,the impact of climate on forest land area is long-ter m and complex;topography and landform affect the spatial distribution chara cteristics of forest land;hydrology has little effect on forest land use change in Shenchi County;and soil has a certain increase in forest land area in S henchi County.Active role;economic and industrial structure and economic d evelopment level provide technical and financial support for the use of forest land and change,which is the driving force for the development of forest la nd;demographic changes have both promoting and negative impacts on the u se of forest land;the effect of policies on changes in forest land useis Posit ive,but it takes a long time to show it.(3)Comparing the country’s per capita forest land area and the world’s per capita forest land area,it can be concluded that the total area of forest land in the study area needs further improvement;from the proportion of var ious types of forest land,it can be concluded that the internal structureof th e forest land is irrational and needs further optimization.In light of thecurre nt situation of forest land in Shenchi County,efforts should be made to imp rove the quality of afforestation and increase the total area of forest land;rati onally develop suitable forest land and dig deeper into the potential of forest land;strengthen the management and protection of forest land resources and promote the healthy development of forest land.
