Research On LUCC And Driving Factor In Jiangjin

Land is the basic natural resources for human survival and development,the most prominent landscape logo of the earth's surface is land use and land cover,also it's the main driving force of Eco-environmental changes.With the deepening and development of global change research, scientists have recognised that human activities on the impact of environmental change. the land use for Human survival and development and the resulting of land cover change is an important component of global environmental change.Thus,As a research entry point,Many global change researchers regard land use/cover change as its research Content to study the role of human play in the global change.This thesis is throughout Jiangjin district of Chongqing as study area, on the basis of various materials widely collected in Jiangjin district and regard land use and land cover changes and driving factors as the research object, by using the LandsatTM image of Jiangjin 1996,2002and2006, combining land use investigation data and related literatures,,carring out the reserch of land use and the type of land cover change and driving factors.Through dealing with, comparing the selection of different periods of LandsatTM image and study time the dynamic change caused by time chages, and combined with lots of collected related statistical data, graphics to establish research references/land-use cover change dynamic database.Then use different models to analyze the change in selected research interval, In the analysis of land use change based on the identified land use change in Jiangjing main driving force is the socio-economic factors. Then the principal components method of screening the human social and economic factors primarily determine the cause of land use/land cover change in the main driving factor.Select jiangjin district land use/land cover changes of social force factor, calculate the large variation of the elastic coefficient between driving factors and land use type change, as further out Jiangjin land use change is the main driving forces of economic development, population growth, urbanization and industrialization and the advancement of industrial restructuring. Combined with the actual situation of the study area, respectively, from economic development, population growth, urbanization and industrialization this three aspect study the driving mechanism of main driving factors. Finally,according to the research of the land use/cover change and driving factors,proposed recommendations of sustainable land use about Jiangjin.
