The Measurement and Variation Analysis of Urban Land Intensive Utilization Degree in Liaoning Province
以辽宁省14个城市为对象，用BP神经网络模型评价2001和2011年城市土地集约利用程度，发现总体上升但个别城市下降，各城市利用状况良好。
Using 14 cities of Liaoning province as the research object,this article uses BP neural network model to do the quantitative evaluation by establishing the evaluation index system of urban land intensive utilization degree.This paper also analyzes and interprets the temporal and spatial variation of urban land intensive utilization degree in 2001 and 2011.The results shows that: The intensive degree of the urban land utilization is overall rising in Liaoning Province. While the intensive utilization value has a modest decline in Panjin and Fuxin city, in summary, each city's land utilization has a good present situation, and they will move toward the high-level, high intensive level development by following the pace of urbanization.
