摘　　要：城市化的快速发展给城市带来了各种各样的生态环境问题,城市热岛效应(UHI)是近年来被广泛关注的一个问题,研究城市热岛效应对改善城市生态环境有着重要意义。以武汉市为例,研究探讨了武汉市景观格局对城市热岛效应的影响。地表温度与景观指数之间的相关性分析表明城市景观的组成与分布影响着城市热岛效应。运用景观格局的方法对城市热岛效应进行研究,对于理解城市生态环境以及通过合理的土地利用规划缓解城市化进程对城市生态环境造成的包括热岛效应在内的各种影响具有重要意义。The rapid development of urbanization have brought a variety of changes in the ecological environment,the effect of urban heat island（UHI）,which has been widespread concerned,is one of these questions,and understanding the effects of landscape pattern on UHI is crucial for improving the ecology and sustainability of cities. This study researched how landscape structure would affect UHI in the Wuhan,based on the analysis of land surface temperature（LST） in relation to landscape metrics. The results show that,there is a strong negative linear relationship between LST and landscape metrics. It indicates that urban landscape configuration influences the UHI. These findings are helpful for understanding the ecology of cities and land use planning to minimize the potential environmental impacts of urbanization.
