Study On LUCC And Driving Force Of Zaoyang Based On RS And GIS

Land property including natural attributes and economic attribute, The former is inherent to land, can not be easily changes in a short time; The latter is mainly reflected in human beings use of the land of the person and the relationship between the land. With the development of society and pursue to higher quality, humans have tried to go to every day how development and utilization of land, make the land cover produced largely change, as humans excessive to use the land resource, has derived a lot of environmental problems, which in turn affect human life. In the human advocates the sustainable utilization of the development strategy in the process, land use and cover change research as the most important since the research content of was one of the great attention in the20th century.By using ENVI4.7software platform and topographic map, to use1995,2006,2010three periods of TM image processing, to extract three periods of land use/cover information. And by using dynamic model, reveals the land use/cover change in features from1995to2010. At the same time by use social economic statistical data, using the grey correlation method to analyses ZaoYang land use/cover change for driving force, and discusses the main driving factors of land use, so as to ZaoYang of land use of the sustainable development and ecological environment construction of macroeconomic policy formulation and implementation to provide the theory basis.The results of the study show that:1. Forest land and farmland as the major type, During the study year, with a total area of2672km2to2641km2, reduce the rate of nearly1%. Construction land from203km2to251km2, rose more than1%. Contradiction between human and to a certain extent is more serious. At the same time other land use also changed, but range is not too much..2. Through the land use/cover the characteristics of space and time, shows that she land use/land cover was largely changed. Compared with the1995-2006for, in the2006-2010land use dynamic is bigger, show that in the period1995-2006improved land use.3. By using social economic statistical, the gray relational analysis, and finally determined that urbanization, population growth rate and the social and economic development level and the progress of science and technology was the major factors to influencing land use/cover changes. And, the cultivated land, wood land, construction land, grassland, water and other land choosing different factors of correlation degree analysis, and concludes that the influence of the main driving factors.
