Xi'an, Land Use Change And The Driving Force Mechanism

Land use, as the human' social economic activities that have the purpose and intention, runs through the whole history progress which human live and development in. Both in company with human activities versus environmental impact, population, resource and environmental challenge increasingly, resulting land use problem have suffer attention out. owing to human versus territorial exploitation utilize activity whereas create soil mantled change, be reputed to be global environment metabolic first cause, wherefore versus land use metabolic research, become for the moment allied nations scholar investigative leading edge and hotspot.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. Meanwhile, the condition on the natural and societal economy development of Xi' an city. And after holding the feature of land use of Xi' an city, studying the problems exist in land use and land conservation in Xi' an city, this paper do analyses in land use change in value, in degree, in structure and in area variation, which analyses dynamic variation character of land use in Xi' an city, disclose the change rule of land use in Xi' an city. And evaluate land use construction, analyses the factors which effect Xi' an land use change.Xi' an city' land use structure exhibition that garden plot, woodland, construct land , non-exploitation land have markedly increased; plow land, water area all submit decrease trend, which is symptomatic of region town melt proceeding expedite and ecological environment pejorative trend; land use metabolic spatial variation distinctness, behave as the city zone within land type change not too, whereas outskirts of a city region plow land slather decrease, construct right-of-way slather increase, outer suburbs each region county, woodland garden plot increase amplitude in favor of the Xi' an city land use structure paradigm emersion garden plot, woodland, construct right-of-way and non-exploitation terra has be markedly increased, plow land, water area big city submit decrease trend, be symptomatic of region town melt tenor eke, outer suburbs each region county, woodland garden plot increase amplitude in favor of out. land use metabolic spatial variationdistinctness, behave as the city zone within land type change not too big, so outskirts of a city region plow land slather reduce, construct right-of-way slather eke, outer suburbs each region.By quantitative and qualitative analysis of socioeconomic driving factors, it was revealed that population, economic development, technology and policy were the main driving factors.In sum, the time-space changes of land use of different topography and economic zones in Xi' an city were studied in this paper. The optimized measures of land use, the rational deploying of resources, the conflicts adjusting between populations and lands were analyzed respectively. Anyway, we wish provides scientific data and suggestions for the managements of resources and the strategy decisions of local economy. Meanwhile, we wish provide helpful suggestions for the Development of China West in Xi' an city.
