摘要
以杭州市四个典型城市湿地为研究对象,通过城市地表温度(LST)的遥感反演和GIS空间分析,探讨了季节和湿地类型对城市湿地局地温度效应的影响.研究发现:1湿地温度效应的季节差异非常明显,季节因素对湿地温度效应的类型、范围和幅度及梯度变化等都有重要影响.2传统的湿地分类与湿地温度效应之间没有直接联系;湿地的面积、周长等是湿地温度效应的重要影响因素;湿地形状对温度效应的影响并不明显.3对各湿地单位水体面积所产生的温度效应进行了比较分析,发现京杭大运河温度效应的效率最高.湿地面积和温度效应的关系极有可能是呈S型曲线的模式.
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 tem-perature 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.
