The Evaluation of Urban Land Intensive Use Based on RS
基于RS的城市土地集约利用评价方法研究

This paper puts forward the index system of evaluation of land intensive use in metropolis by using RS date which is the primary data source in this system.By analyzing the characteristics of the remote sensing image (IKONOS),we can therefore interpret the types of urban land use according to the method of RS interpretation.We compared the two methods of integrated evaluation method and artificial neural network (ANN) method by using the index information of potential evaluation of urban land intensive use and found ANN is a feasible evaluation method,which can reflect the complex nonlinear relationship between independent variables and dependent variables.We built the method system to evaluate urban land intensive use based on RS and ANN.This model is applied to evaluate the land intensive use in Shijiazhuang.Practice has proved this kind of evaluation method may be more time-effective,more practicable,more convenient and the appraisal result is more objective.
