Analysis On Land Use Dynamic Change And Driving Forces Of Jiangle County

The land is labor and social means of production and agricultural production structure and land quality,land use in different areas with the development of social economy,affected by natural and social factors in different degrees and constantly changing,and the impact on the ecological environment and regional economy.Land use change research has received great attention,revealing the driving force of land use change is of great practical significance for the rational development and utilization of land resources,the formulation of land use policy,and the sustainable use of land resources.In this study,Jiangle County as the research object,based on land survey data of 2006-2014 based on the analysis of the current situation of land use in Jiangle County,the land use structure and degree of land use change.Using quantitative analysis method and qualitative analysis of principal component and grey correlation analysis of the influence of land use change driving factors,determine the impact of land use main driving factors the changes and the maximum correlation factor.According to the characteristics and laws of Jiangle County land use status quo and problems of land use,the rational use of land,improve the policy suggestions and measures of land intensive utilization.The conclusions of this paper are as follows:Jiangle County land use mainly agricultural land,the forest area accounted for 86.6%of the total area,the largest share,good ecological environment,rich tourist resources;cultivated land accounted for 6.06%of the total area,a smaller proportion.Construction land accounted for 4.51%of the total area,the proportion of low and uneven distribution;unused land area accounts for 1.15%of the total area,and gradually reduce the proportion of low,arable resources shortage during.2006-2014 construction,Jiangle County land area increased the number of hectares;garden land,grassland and unused land due to the adjustment of agricultural structure and land the development of reason has the trend of decrease;cultivated land and woodland is reduced after the first increase in law.(2)2006-2009 years,cultivated land,garden,woodland,grassland and other land types of land use dynamic degree are-0.12%,-1.11%,-0.07%,-0.73%,-0.76%,are less than zero.Urban village and industrial land dynamic degree in 2006-2009 and 2010-2014 were 5.83%,2.03%,higher than that of type other land use over the same period,that economic development and urban village and industrial land increased is related.The comprehensive land changes during 2006-2009 in Jiangle County is 0.0804%,the comprehensive land changes in 2010-2014 to 0.0401%.can be seen that the comprehensive land use conversion rate in Jiangle County is relatively slow.(3)through qualitative and quantitative analysis on the driving forces of land use change in Jiangle County,it is concluded that the main driving factor is the natural change of natural resources,topography,climate and hydrology,soil factors of land use in Jiangle County,social economic driving factors mainly for the population,economy,technology and policy.By using principal component analysis method to get the influence of music the two main factors of county land use change for economic development,living standards,population and city factors.Through the analysis of grey correlation,and correlation factor that most agricultural land is the population,living standard,city level and industrial structure;and construction land use change correlation factor is the largest population and the city and other factors;land use change correlation is the largest population and the city.
