城市区域内复杂的建筑布局和形式导致了建筑间的多次反射辐射现象，而这种多次反射辐射一直是研究的难点问题，它直接影响到了城市区域内热环境的分析。以建筑间多次反射问题理论为基础，将城市综合反射率问题转换为与城市空间结构相关联的几何参数问题，使问题的分析过程具有一定的操控性。最后引入了实际案例进行分析，得到了考虑城市空间几何结构影响后的综合反射率，结果显示综合反射率比未考虑多次反射情况下的值要低32畅4％，该结论为城市热环境分析中反射率设定值的修正提供了重要的参考价值。

The complicated architectural layout and form within urban area lead to the phenomenon of multiple‐reflection radiation in the urban area .And this multiple‐reflection radiation directly affects the thermal environment in urban areas . This paper is based on the theoretical basis of multiple‐reflection between the buildings and converts the problem of urban integrated reflectivity into geometrical parameters which are relevant to the urban spatial structure .At the same time ,a case study was taken to obtain an integrated reflectivity which had taken the structure of urban space into account .The results show the integrated reflection is lower 32.4% than the normal situation .
