摘要
以京津冀区域发展战略中的13个城市为研究单元,选取8个年度时间截面,研究京津冀地区城市土地经济密度时空分布特征。通过利用特定的指标和模型研究发现,2010-2017年京津冀城市土地经济密度呈现出不断上涨的趋势,但各城市的相对发展速度具有明显差异且有不断扩大的趋势,研究区城市间的发展梯度明显,并未出现明显的向区域中心城市靠拢的空间集聚现象。
Eight annual time sections of thirteen cities in the development strategy of Beijing-Tianjin-Hebei are taken as a research about the spatial and temporal distribution characteristics of urban land economic density.with the specific indicators and models,we found that the urban land economic density in Beijing-Tianjin-Hebei present a rising trend from 2010 to 2017,but the relative growth rate are obviously differences and had a trend of continuous expansion.The development gradient among the cities in the study area was evident and there was no obvious spatial agglomeration phenomenon among the regional central city and the surrounding cities.
