基于BP人工神经网络的城市土地利用效益评价研究——以辽阳市为例

摘要

采用BP人工神经网络模型,通过构建辽阳市城市土地利用效益评价指标体系,对2000～2009年辽阳市城市土地利用效益进行了定量评价.结果表明:辽阳市近10年的城市土地利用效益水平呈不断上升趋势.%The paper evaluated urban land use efficiency for Liaoyang city by using the model of BP neural network and indexes system during 2000～2009. The BP neural network was applied and trained by training data after having dealed the evaluation indexes with dimensionless mode. The results indicated that land use efficiency index of Liaoyang city is rising.
