Urban wetlands play a significant role in the sustainable development of the urban eco-environment. The time-spatial evolution character and rules of the wetland landscape pattern in Wuhan were quantitatively analyzed using landscape ecological methodologies. The following results have been obtained:① The decrease in urban wetland area was 137.50 km
2
and in natural wetland area was 281.87 km
2
on the contrary
the increase in artificial wetland area was 144.37 km
2
.② Urban wetland landscape diversity decreased,evenness reduced,and dominance increased from 1987 to 2005. These changes reflect that urban wetland landscape types gradually tend to be assimilative.③ The fragmentation of reservoir and pond wetlands was the largest
which indicated that the impact of human activities was the biggest for the reservoir and pond wetlands.④ The centroids of river and lake wetlands moved southwest and the centroids of reservoir and pond wetlands moved southeast.⑤ The increasing warm and dry climate,the rapid population growth
and the rapid economic development as well as the rapid urbanization are major reasons for the structural changes in urban wetland landscape pattern from 1987 to 2005.
