长沙市区地价的空间分布特征及其影响因素

Spatial distribution and influencing factors of urban land price in Changsha City

利用长沙市2003～2009年上半年的土地交易资料,采用GIS空间分析和计量经济学相结合的方法,得出长沙市区商业、住宅和工业出让地价分布的空间结构图,分析三类用地地价的空间分布特征及其影响因素。结果表明:(1)土地用途不同,其地价的空间分布也不同,商业地价对商服繁华度要求较高,高值区集聚在市中心(以五一广场为中心);住宅地价对环境质量要求较高,高值区相对商业地价集聚度有所下降;工业地价由于有较高的对外交通条件要求,其空间分布相对比较分散、均匀。(2)作为典型的单一中心城市,长沙各类地价空间变化的影响因素,因土地用途而异,但商服中心影响度对三类地价都存在显著影响。

Based on the land transaction data in Changsha from 2003 to the first half of 2009,GIS and econometrics methods were used to compile three spatial structure maps on the distribution of commercial,residential and industrial land prices.Then this paper analyzed the spatial distribution of the three types of land prices and its influencing factors in Changsha.The results are shown as follows.First,the spatial distribution of land price is different in terms of land use types.Commercial land price calls more for the degree of CBD,and the high value areas are concentrated near the center of the city—Wuyi square.Residential land price is consistent with the level of environment quality,and compared with commercial land price,the degree of aggregation for areas with high values comes down to some extent.Industrial land price,which depends more on external traffic factors,is relatively sparsely and evenly distributed in space.Second,the factors affecting the spatial variation of the three types of land are different due to different usages of the land.Degree of CBD is the most important factor among the factors affecting spatial land change in the single central city—Changsha land price,which also has significant influence on the three types of land use.
