Research On Spatial Pattern Of Urban And Rural Residential Land Use Efficiency And Impact Factores In Shijiazhuang City

Land is a complex and giant system, land use/land cover change research has become a central issue of global environmental change. As the carrying body of urban and rural residential land. land area is limited. Due to factors such as unreasonable urban and rural planning, and quick growth of population, other land categories, especially arable land was occupied by the expansion of urban and rural residential land, result in that substantial reduction of arable land, environmental deterioration, therefore it is one of the main tasks to achieve dynamic balance of arable land, improve land use efficiency in urban and rural residential land currently, that to formulate reasonable the urban and rural planning, and identify the main factors affecting the expansion of urban and rural area.Shijiazhuang, capital of Hebei Province, has a difference in the levels of economic development between urban and rural areas, and unique landforms form (the western mountains and the eastern plains), so the hilly and plain areas in Shijiazhuang was selected in this study, It was study that the spatial pattern of land use efficiency per capita and its impact factor in urban and rural residential land in 2006.It was shown that there are great differences in land use efficiency per capita between the urban and rural residential land and between mountain areas and the plains in 2006 in Shijiazhuang. Land area per capita in Shijiazhuang city is 91 square meters per capita, while it is more than one hundred square meters per capita . in other cities that of and upgrade than county town, with the exception of Xingtang county of 90 square meters per capita, the numbers of land area per capita in rural residential land are generally much higher. Residential land in the western mountain area are small, fragmented distribution. Due to poor natural conditions and not higher level of economic development, residential land per capita is relatively lower; residential land in the eastern plains area are large and concentrated. Result from superior natural conditions and the higher level of economic development, residential land per capita is relatively higher.Because the urban and rural residential land per capita area is different. To carry out an analysis of county as a unit, which is based on country per capita on the urban and rural land for construction of the target requirements, also on the different unattainment rates of the per capita land area of cities, towns and rural residential land in Shijiazhuang City.The complicated driving factors which lead to the differences of the land area per capita between urban and rural areas can be summarized as two aspects, the natural factors and the socio-economic factors. The characteristics so differentiate between urban and rural in the natural conditions, historical circumstances, economic development and population growth, etc., that the driving factor is different in urban and rural residential land which impact the efficiency of the spatial pattern of land per capita. Accordingly, different indexes were selected to evaluate from the population scale, level of economic development, land quality land quantity and habitation area. Using correlation analysis and multiple linear regression analysis, the following facters were filtered out as the main impactors of the differences in the per capita land area between urban and rural residential land: the proportion of irrigated land, the grain output per capita ,arable land per unit area, and the mean growth rate of the last 5-year's regional gross domestic product.Innovation in the thesis:(1) The 3S technology was applicated to analyze the spatial pattern of per capita land use efficiency in both urban and rural residential land in Shijiazhuang City.(2) Studying on the different unattainment rates of the per capita land area of Cities, towns and rural residential land in shijiazhung,which is according to the County as a unit.(3) Some indicaters were selected from population scale, level of economic development, land quality quantity of land and habitation area, the main factors affects the differences in per capita land area between urban and rural were filtered out and analyzed use methods of correlation analysis and multiple linear regression analysis.
