基于LOGISTIC模型的城市扩展时空模拟——以深圳龙岗区为例

龙岗区是深圳市面积最大的市辖区，在深圳城市扩展中占有重要地位．在综述国内外采用LOGISTIC模型进行土地利用时空模拟的基础上，改进原始模型，将动态交通数据和空间滤波引入模拟流程．以龙岗区为例，基于改进模型尝试对中小尺度的单个城区进行城市扩展的时空模拟．结果显示，模型在中小尺度城市扩展模拟方面具有较好效果．

Logistic modeling to simulate urban growth——A case study of Longgang district

Longgang district is the biggest area among Shenzhen city,and plays an import role in urban growth.Based on the reviewing of domestic and international literatures on simulating spatiotemporal changes in land-use using logistic model,an improved model,which introduces dynamic traffic data and spatial filtering into simulating process,were used in the spatiotemporal simulation of Longgang's urban area expanding.The improved logistic model produces a better land-use change simulation result for single district at micro scale.
