摘要
综述了国内外在人口数据空间化研究方面的进展,并分析了其优缺点。在此基础上,提出了基于建筑物的人口数据空间化方法,设计了基于建筑物的人口数据空间化模型;并以重庆市主城区的第六次人口普查数据为例,得到了较细粒度的人口空间分布结果。结果表明,由于受"四山"和"两江"的影响,重庆市人口空间分布呈组团化和沿主要道路分布特征,且各组团有逐渐合并的趋势。对于城乡规划编制、城市空间政策制定、突发事件应急处理以及灾后损失评估具有重要意义。
In this paper,we reviewed the progress in the spatialization of population,and analyzed their respective advantages and disadvantages.And then,we proposed the method of spatialization based on the building and designed the model.Finally,we verified the model by the sixth census of Chongqing,and obtained a fine-grained population spatial distribution results.The result shows that the population of Chongqing City distributes along the main road and concentrates in group due to the“Four Mountains”and“Two Rivers”.This study is benefit for urban and rural planning,urban space policy setting and emergency disposal and so on.
