Abstract:In this study, remote sensing data of Wuhan City, Hubei Province, China in 1996-2001 were selected to ex-tract wetland landscape information. Several landscape indices were used to evaluate the changes of landscape patternwithin the five years, including patch number, patch density, patch fractal dimension, landscape diversity, dominance,evenness, and fragmentation indexes. Then, transformation probabilities of wetland landscapes into non-wetland land-scapes were calculated based on Markov Model, and on these grounds the relationship between changes of wetlandlandscape pattern and urban construction was analyzed. The results showed that fragmentation degree of all wetlandtypes increased, lake area declined, and dominance of natural wetland decreased. The reasons for these results weremainly because of urban construction. According to the features of abundant wetland in Wuhan City, we suggested thatprotection of wetland landscape should cooperate with urban construction, which means wetland should become im-portant part of urban landscape.
Keywords:wetland landscape  urban wetland  wetland protection  Wuhan City
