Abstract

Anthropogenic activities play a key role in wetlands evolution during the processing of urbanization. In this paper, Wuhan, which is known as a “Hundred-lake city”, was selected as an example for wetlands morphology analysis by fractal. Firstly, the border information of 19 lakes was extracted from two time-series Landsat TM images for the years 1991 and ETM+ 2002.By using GIS tools, the fractal dimension for those wetlands were calculated. Secondly, the relationship between fractal dimension changes and human activities were also analysed. The fractal dimension of the 19 urban lakes was decreased from 1991 to 2002 during the process of Wuhan urbanization. The increasing population, industrial structure boosting and economy development affected the urban land use changes. The infilling of lake which caused the lake loss, was considered to be the primary factor for the lake’s fractal dimension decreasing. It states that the human activity contributed much more to lake morphology evolution during the urbanization of Wuhan City
