摘　　要：文章提出了郊区县经济发展潜力模型,分析了北京各郊区县的经济发展态势与优势,从而反映人类开发活动的强弱。应用GIS技术和景观格局分析方法研究各郊区县的景观格局特征及其与经济发展潜力的相互关系;并且以河流水质数据为基础,分析各郊区县河流综合污染指标与经济发展状况的关系。结果表明:景观指数与经济发展潜力之间存在较好的相关性,其主要影响因素为各郊区县公路密度。河流的水质与各郊区县经济发展潜力之间的关系较为复杂,其主要影响因子为各郊区县的固定资产投资比重、产业结构及其与城区之间的产业梯度。The potential model of satellite city is extended to the potential model for suburbs in order to characterize the development situation and the intensity of human development activity.The landscape pattern characteristics and its relationship with the development potential are analyzed by GIS and landscape structure analysis methods,based on land-use map.It is found that there is apparent correlation between landscape indexes and development potential which is mostly affected by the intensity of roads.The relationship between the comprehensive pollution index and social-economic situation is analyzed used river water quality.The result shows that the relationship between river pollution and development potential is complex,but is affected by fixed assets investment proportion,industrial structure and the industrial gradient to central city.
