Abstract: Land use in urban areas is crucial for urban land management decision-making, environment monitoring and urban planning. According to the landscape ecology concept that the landscape patterns within the same land use type are similar, this paper presents a new land use classification approach which integrates landscape characteristics and high-spatial resolution remote sensing data. Some key landscape metrics were selected to quantify the landscape patterns of different land uses. Then, the integration of SPOT image and landscape characteristics was applied to land use classification within the 5th Ring Road of Beijing. The overall land use classification accuracy was 85.9% with Kappa parameter being 71.1%. The results show that the specific landscape patterns of different land use types would significantly contribute to improving land use classification, and could potentially be applied to other urban areas.
