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

With the prominent increase of global population, resource and environmental issues, the land use/land cover change research more and more attention has been paid, and gradually become a cutting-edge research topics in global change research. It is of great practical significance for the coordination of regional economic development to improve the regional ecological environment, and promote regional sustainable development.Shimen in Hunan, Hubei, boundary, complex and diverse landforms, economic backwardness, fragile ecological environment in recent years, along with social development, land use/land cover strong. Therefore, of Shimen land use/land cover study has important implications for the correct guidance of the people of the land use to improve the regional ecological environment and promote the coordinated development of economy.In this paper, Shimen Regional Overview on the basis of the analysis of land use status and the1996-2009land use change, from the perspective of qualitative and quantitative analysis of the driving forces of land use change, and then put forward the countermeasures of sustainable land use. By analyzing the obtained:Shimen land use types, use types mainly agricultural land, land use diversity decreases gradually from southeast to northwest, differences in location advantages of each township, there is extensive use patterns in the process of land land-use, the use of low intensification.Land use change significantly, agricultural land and construction land is a substantial increase in the number of unused land to reduce the number of; the rate of change of other land for construction the fastest growing, the overall annual rate of change of0.31percent, to utilization of Composite Index was6.38%, The Shimen land use in development stage.Qualitative analysis of the driving forces by of Shimen land use obtained the driving forces affecting land use change factors including:climate, topography, hydrology, soil, population, economy, industrial structure, policies, while the use of principal component analysis method Shimen County land use changes in the quantitative analysis to come to the economic development, urbanization and industrial restructuring is the main driving force of Shimen County land use change, and the calculation of derived composite score of the driving force has gradually increased, indicating that the Shimen land use of the driving force year by year. Finally, the combination of Shimen County land-use problems and driving force of the proposed sustainable land use measures, which provide a theoretical reference for land policy makers.The full text is divided into eight parts:The first part introduced the land utilization change background, the significance, the research present situation and this article research technique.The second part of the relevant principles and methods of this study. Papers in the land level of theory, sustainable use of the theory and land ecological and economic systems theory based on the distribution pattern of the land, the land dynamic change of land use and land area of significance of the theory in detail.The third part is an overview of the study area, focusing on the natural profile and socio-economic conditions of the study area.The fourth part of the main analysis in the study area land use status quo on the number and structure of the various land use types in the study area, land use patterns and land use spatial pattern of distribution.The fifth part of the study area land use change analysis. Analysis of regional differences in the study area land use of the number of changes in the structure, land use dynamic degree of change, the degree of land use change and land use change.Part VI from the perspective of qualitative and quantitative analysis of the driving forces of land use change, including the main methods of quantitative analysis of the main ingredients.Part VII of the problems of land use and combination of the driving force analysis of the proposed land sustainable use of countermeasures.The eighth part of the research findings and research.
