基于神经网络模型的城镇建设用地扩张预测

Prediction of Urban Construction Land Based on Neural Network Model

城镇建设用地扩张是基于社会经济发展的客观条件与政府规划决策的主观条件共同作用的结果。以贵州省都匀市为例。根据都匀市2009—2013年土地利用变化情况。总结了都匀市城镇建设用地扩张规律，运用灰色模型与神经网络相结合的方法，并依据都匀市城市总体规划与重大工程建设．对都匀市未来城镇建设用地扩张方向与规模进行了预测。

The urban construction land expansion depends on both the social and economic development and government planning. Based on the land use changes of Duyun from 2009 to 2013, this paper summary expansion rule of urban construction land and predict the scale and the direction of urban construction land by using the neural network with grey model.
