In a case study of Bishan district of Chongqing, based on the data of the urban and rural construction land and population in the study area in 2004-2014, the growth elasticity coefficient method was employed to analyze their evolution trajectory. The results showed that urban construction land expanded rapidly, at a growth rate of 182.5%, while rural construction land decreased by 4.12%——a great discrepancy between the two. The urban construction land-population growth coefficient was 1.81, suggesting a greater growth rate for urban construction land than for urban population and a tendency to land urbanization, and there existed an unbalanced regional urbanization development. The rural construction land-population growth coefficient was 0.17, indicating a slower decline of rural construction land than that of rural population, and a dysfunctional human-land relationship existed, in different degrees, in 10/13 of the towns. The distribution of the regions with dramatic changes in human-land relationship was similar in urban and rural areas, with the central urban area of Bishan as the center, which influenced its adjacent towns in a circular pattern %K 土地资源 %K 人地关系 %K 弹性系数 %K 城镇化< %K br> %K land resources %K human-land relationship %K modulus of elasticity %K urbanization %U http://xbgjxt.swu.edu.cn/jsuns/html/jsuns/2017/11/201711018.htm
