Abstract:

Accessibility of urban waterfront not only reflects the resistance of spatial distance,but also represents waterfront attraction and the demands on waterfront service.It is affected by the surrounding quality of the waterfront,population density,land use and the traffic condition.By taking account of the above influential factors and applying the concept of potential model,a model is put forward to evaluate the accessibility of urban waterfront based on grids partition.The model partitions the area equidistantly,computes the population distribution density,minimum resistance cost and comprehensive quality of the waterfront based on Arc GIS93 platform.The accessibility of each waterfront in Yixing central city is evaluated.It may offer help to make determination when the waterfront is designed and constructed
