- 摘要:
- 农村居民点用地空间分异研究对优化居民点用地结构和布局，统筹城乡土地利用具有重大意义。文章采用居民点相对变化率指数、变化强度指数、综合变化程度指数模型，研究重庆市农村居民点用地总量变化及人均用地变化特征，并对总量变化空间分异类型和人均用地类型进行划分，结果显示：直辖以来，重庆市农村居民点用地总量年变化率呈下降趋势，表现为上升-下降-上升-下降的倾斜波动型变化特点；居民点综合变化程度较小，建设用地综合变化程度要远远大于居民点综合变化程度，综合变化程度一直呈较缓慢上升趋势，但各个区县差异较大，绝大部分区县属于稳定型；人均农村居民点用地面积一直呈持续增长趋势，与农村居民点总量变化呈反方向变化；人均用地超标，集约利用水平低，人均用地类型主要为严重超标型和中度超标型。
- Abstract:
- Research on the spatial differentiation of rural residential land is of great significance to optimization of land structure and the layout,and also to overall urban and rural land use.This paper employed models of relative change rate index,change intensity index and synthesis changes degree index to study the total quantity change and per-capita variable quantity of rural residential land in Chongqing,and then carried on the division to the spatial differentiation type of total quantity change and the per-capita land use type.The result indicated that the annual gradient of rural residential land quantity in Chongqing assumed declining trend,displaying for the rise-drop-rise-drop inclined fluctuation change characteristic since direct jurisdiction.Compared to the construction land synthesis change degree,the residential land synthesis change degree was small,but had assumed the slow trend of escalation.And also there was great difference among different counties,most counties were in stability mode.The per-capita variable quantity of rural residential land had assumed the sustained growth tendency,presenting the reversed direction change with the total quantity change.With exceeding per-capita rural residential land quantity and low level of intensive utilization,the per-capita land-use types mainly are serious exceeding type and moderate exceeding type.
