相互作用模型在城市规划中的运用

城市增长是未来几个世纪备受关注的问题。为了保证城市可持续发展，有必要对城市的发展进行监控，但预测城市的发展趋势需要一些空间信息的支持、卫星图像能够提供可靠的信息用来评定城市增长的不同状态，而预测未来的建设区段则更加重要。本文构建了相互作用模型（interaction models），或者更精确地说叫潜力模型（potential model），以确定城市空间的扩展方向。该模型被运用于法国斯特拉斯堡地区的分析，采用了两张遥感数据影像，一张用于模型处理，一张用于检验结果。另外，模型还运用GIS技术以提高准确度，同时还考虑到了交通网络。

Interaction Model Application for Urban Planning

Urban growth is a terrific issue for the nextcenturies. Monitoring the urban development in orderto assure sustainable cities in the future is an absolutenecessity. Decision support in this domain needssome spatial information enabling to forecast theurban development trends. Satellite imagery mayprovide reliable information assessing different statesof urban growth, but it is necessary to anticipatewhere future built areas might be located. This paperpresents the interest of interaction models, moreprecisely the potential model, to define futuredevelopment zones. This model is applied to theStrasbourg area (France) using remotely sensed data.Two images are used, one to initiate the modelprocessing and the other to validate the results. GIScapabilities are applied to refine the results, addingtraffic network in the study.
