Abstract: This paper takes four typical urban wetlands of Hangzhou for example and discusses the influence of season and wetland type on the temperature effect of urban wetland by means of remote sensing and GIS spatial analysis. The results show that: (1) the seasonal difference of wetland’s temperature effect is very obvious. Seasonal factors have an important influence on the type, range, amplitude and gradient change of urban wetland’s temperature effect. (2) There are no direct relationships between traditional classification system for wetland types and urban wetland’s temperature effect. Wetland’s size and perimeter have an important influence on its temperature effect, while the influence of wetland’s shape on the temperature effect is not obvious. (3) Comparing the efficiency of different wetland’s temperature effects, we find that the efficiency of Grande Canal is the highest. The relationship between wetland size and temperature effect is most likely to be S curve model.
