摘　　要：利用计量统计方法和空间分析方法,基于村镇空间开发强度和村镇建设用地承载系数等指标分析2010-2016年中国村镇建设用地的时空演化特征,并揭示市域单元村镇建设用地和乡村人口的空间关联关系。结果表明:1)2010-2016年中国村镇建设用地规模和村镇空间开发强度呈低速增长,其中建制镇建设用地在村镇建设用地的增量和增速方面贡献最突出;2)市域村镇建设用地的规模和扩张速度存在冷热点的空间错位,以黑河—腾冲线为界分别呈现“东热—西冷”和“东冷—西热”格局;3)市域村镇空间开发强度高水平区集中分布在黑河—腾冲线东部的平原区,具有时空稳定性;4)市域村镇建设用地承载系数表现为“南热—北冷”的地域分异特征,冷点的市域村镇建设用地规模和乡村人口规模关联关系存在东西空间分异;5)市域村镇建设用地扩张速度对乡村人口流动水平具有差异化的空间响应,其中东北地区“高—低”型和华北地区“低—低”型的市域乡村人口流出对村镇建设用地扩张速度约束较显著。Based on a series of statistical and spatial analysis methods,the spatial development intensity and the carrying coefficient of construction land in villages and towns are regarded as analysis indexes,to explore the spatial and temporal evolution characteristics of construction land in villages and towns in China from 2010 to 2016,and reveal the spatial correlation between rural population in the municipal administrative area and construction land in villages and towns.It is found as follows.1)The scale of construction land and the spatial development intensity of villages and towns both present a low-speed growth from 2010 to 2016,and with a prominent contribution of construction land in designated town to the growth.2)There is a spatial mismatch of"hot and cold spots"in the scale and expansion rate of construction land for villages and towns in municipal units,which is presented in the spatial pattern of"hot in the east-cold in the west"and"cold in the east-hot in the west"respectively,taking the Hu′s Line as the boundary.3)The high level areas of spatial development intensity of villages and towns in municipal units are concentrated in the plain area in the east of the Hu′s Line,with spatial and temporal stability.4)The carrying coefficient of construction land for villages and towns in municipal units shows a geographical differentiation pattern of"hot in the south-cold in the north",and the correlation between the scale of construction land and rural population in villages and towns has a spatial differentiation from east to west in"cold spots".5)In the municipal administrative area,the expansion rate of construction land in villages and towns shows different spatial responses to the level of rural population mobility.Thereinto,the"H-L"type in Northeast China and the"L-L"type in North China display a significant constraint on the expansion rate of construction land in villages and towns.This study could provide guidance for improving the optimization of territory space and the"smart shrinkage"of village
