基于GIS的西安市地价空间分布规律研究

Land Price Space Distribution Law of Xi'an Based on GIS

地价是影响土地交易的重要因素,是促进经济发展的重要推动力。土地使用制度的改革,土地市场的完善,以及计算机技术的日益进步,对研究城市土地价格的空间分布规律已具有重要的现实意义。本文基于对西安市土地市场的调查,依据西安市主城区2011年下半年-2012年上半年,在售不同物业房地产项目的市场价格数据,利用成本法推算出不同区域的土地价格,采用统计分析与GIS空间分析相结合的方法,利用数字地价模型,对西安市已收集到的样点数据进行分析,总结出西安市地价的空间分布规律,从而对西安市地价发展趋势进行预测。
