【摘要】：土地与人口的城镇化失调已久,厘清内在的变化机理,是协调人地结构矛盾的迫切需求.本文以重庆市璧山区为例,采用增长弹性系数法,利用2004-2014年的城乡建设用地和人口数据,分析二者的关系演变轨迹.研究结果表明:1)城镇建设用地增长率182.5%,农村建设用地减少率4.12%,二者增减幅度差距大;2)城镇人地增长弹性系数为1.81,城镇建设用地增长快于人口增加,有土地城镇化倾向,且城镇化发展存在区域不平衡;3)农村人地增长弹性系数为0.17,农村建设用地减少慢于农村人口的析出;4)城镇人地关系与农村人地关系变化剧烈的地区分布存在一致性,形成以璧山主城为中心的向相邻街镇震荡的环形格局.农村建设用地的增减决定了农村人地关系是否协调,应加强对农村闲置宅基地的整治.另外,应促进农村人口城镇化,提高城镇建设用地集约利用度.
[Abstract]:The urbanization of land and population has been out of balance for a long time. It is an urgent need to coordinate the contradiction of land structure to clarify the internal mechanism of change.Taking Bishan district of Chongqing as an example, the paper uses the method of growth elasticity coefficient to analyze the evolution of the relationship between urban and rural construction land and population data from 2004 to 2014.The results show that the growth rate of urban construction land is 182.5%, the reduction rate of rural construction land is 4.12, and the gap between the two increases and decreases is large. The elasticity coefficient of urban land growth is 1.81. The urban construction land increases faster than the population, and has the tendency of land urbanization.The elasticity coefficient of rural land growth is 0.17, and the decrease of rural construction land is slower than that of rural population. 4) there is consistency between urban man-land relationship and rural human-land relationship.Bishan formation of the main city as the center of the adjacent street town concussion ring pattern.The increase or decrease of rural construction land determines whether the relationship between people and land in rural areas is coordinated, and the regulation of idle rural homestead should be strengthened.In addition, we should promote the urbanization of rural population and improve the intensive utilization of urban construction land.
