摘要
Abstract
Under RS and CIS support, the remote sensing images of 3 stages of Wuhan City were analyzed and treated, the information about scope of buildup region of this city was extracted and the enlargement and evolution image of the buildup region was obtained. Then the enlargement of urban land utilization space of this city was analyzed using spatial fractal model and it was found that the spatial fractal dimensions were being increased in 1991 - 1995 and 1995 -2005, indicating that the major enlargement in urban area of Wuhan City in these 2 periods was external enlargement, its irregular degree of edge was increased, its outward enlargement stability was decreased and its outward enlargement showed more and more haphazardry, with trend of further complication. Finally, the driving force for enlargement and evolution of land utilization space of Wuhan City was analzyed, and then it was found that the system and policy factors, social and economical factors and population factor were its main driving factors.关键词
