The history and the present situation of study on urban morphology and land use structure based on the fractal theory are briefly introduced and reviewed.The model and its meanings of the fractal theory on urban morphology research is also introduced and explained.Taking Changsha as an example,the authors draw 1979,1996,2003’s fractal data message of its urban morphology by writing compute program and using ArcGIS soft,and calculate the fractal dimensions of its urban morphology and land use structure of different periods.The end shows that the tendency of fractal evolution gradually changing from the chaos to the order has been existing in urban morphology and land use structure in Changsha,and its causes of this phenomenon are mainly made for the development of urban economy,the innovation of regionalism and the modification of city planning.At the same time a few of questions in land structure also have been discovered,including that the area of the green land and the traffic land is smaller and their distributions are also more centralized.In this study,the dimension inclusion theory is confirmed,which means all the dimensions of different land use sorts are smaller than that of the whole urban morphology.Some significance about the study to Changsha urban planning also has been put forward.
