Using the Fractal Theory to establish the fractal structure models, we analyze the complexity and stability of various landscapes’ distribution with fractal dimension value. The spatial distribution characteristics of landscape mosaic structure are also expounded. At the end of the paper we discuss the relevant problems on the main factors which control and effect on the spatial pattern of landscapes as well as on landscape optimization and management.展开更多

文摘With the development and changes of the times,many cities have to face the problem of renewal.However,in the context of globalization,urban renewal also makes urban cultural characteristics and regional characteristics inevitably missing.Therefore,we should pay attention to the protection and planning of regional historical and cultural heritages in the process of urban renewal,which plays an important role in the construction of urban characteristics and the shaping of city card.Xigu area of Tianjin also faces the problems of cultural loss and need for reconstruction,its function,layout,industrial structure and land use are adjusted and optimized in this article,with a view to showing the value of historical and cultural heritage and context of regional history.
