Analysis On Land Use Change And Its Driving Forces In Ezhou City

Land is the most basic natural resource and the material basis during the course of human survival and development.Since the 90's,20th century,with the prominent of population,resources,environmental issues and the deepening research and development of global change,people begin to recognize that the research on land use change take an important role on understanding of global environmental change research.So the research of land use change has become cutting-edge research and hot topic on global environmental change,and further strengthened the study of land-use change.Based on the analysis and summary of research trends domestic and overseas, in this article the research contents and methods on the problem are put forward. This paper takes Ezhou as the main research object.On the basis of correctly grasp of Ezhou's natural and socio-economic situation.With type second classily for research object,through its analysis of the dynamics eleven years(1996-2006),the paper revealed the identity and category changes from different angles,which are changes of value,degree,structure,space situation.Based on the land use change,the paper analyzes its natural and socio-economic driving force.By qualitative analysis method of nature driving factors,its Geological features,Climate,soil and hydrological factors are checked, and the socio-economic factors through qualitative and quantitative method.This Paper firstly takes Ezhou as the main research object.By analysis of 13 correlation socio economic factors of the land use change from 1996-2006,then use the principal component analysis method in SPSS soft to analyze.Analysis results prove that socio-economic factors which influenced the land use change could conclude to 4 kinds-economic development,population growth,urbanization,industrial structure adjustment.Moreover,the administration and planning factors are also the important driving factors of land use change,they will play specific role in a certain period of time. Research results shows that the Ezhou economics have got a great improvement as a result of the Wuhan city circle 1+8 strategy implemented and the impact of the real estate investment,Increase in the amount of real estate investment is particularly evident,with an average annual growth rate of 7.88 percent,to a certain extent propelled the use of cultivated land for urban construction.Economic growth makes land use way change.The area of arable land decreased by 317 hectares from 1996-2006.At the same time,mining settlements and independent sites, transportation sites respectively both increased.In addition,the construction of three major economic development zones is an extensive expansion.The expansion realized the transformation from collective ownership of rural land to state-owned land,but also from agricultural land to construction land.Population growth,not only need more construction land for meeting housing needs,but also promote urbanization.The process of urbanization promotes the structure changes of urban land.The population concentrating,industry focus and geographical spreading make land non-agricultural.The way of life and values also change the original structure of land use.The expansion of urban land made up of the industrial land,living space and land for the composition of the tertiary industry lead to the reduction of agricultural land.Conversion of land use structure improves Ezhou land-use function, to a certain extent also promotes Ezhou industrial restructuring.In turn,during the course of the industrial structure continuously adjusting,the land use structure must be moving towards a more reasonable direction.Finally,the paper concludes the problems in the Ezhou land use.From the sustainability point of view,the author puts forward 6 points strategy and suggestion for land use,in order to give some reference for the rational utilization of the land.
