Changes of urban wetland landscape pattern and impacts of urbanization on wetland in Wuhan City

Abstract

In this study, remote sensing data of Wuhan City, Hubei Province, China in 1996–2001 were selected to extract wetland landscape information. Several landscape indices were used to evaluate the changes of landscape pattern within 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 landscapes were calculated based on Markov Model, and on these grounds the relationship between changes of wetland landscape pattern and urban construction was analyzed. The results showed that fragmentation degree of all wetland types increased, lake area declined, and dominance of natural wetland decreased. The reasons for these results were mainly because of urban construction. According to the features of abundant wetland in Wuhan City, we suggested that protection of wetland landscape should cooperate with urban construction, which means wetland should become important part of urban landscape.
