基于人居环境适宜性的市域人口增长调控分区研究──以南京市为例

构建人口规模收益函数和外部成本函数,对南京市主城、郊区和县城进行最优人口规模分析;进而通过人口随机分配模型和基于人居环境适宜性评价的优化目标函数,以预测的总人口规模和圈层人口最优规模为约束条件,采用蒙特卡洛法进行求解,获得人口的优化分布结果,与现状人口分布相比,把南京市域空间划分为四类人口发展功能区。研究认为,商业街区和老街区如湖南路、新街口街道、洪武路街道、朝天宫街道等老街区人口密度过高,需要进行人口规模的控制或调减;处于郊区的东山镇、沿江街道、仙林街道等,人居适宜性相对较高,现状人口密度较低,应快速集聚人口;南北两翼以及生态保护区的生态敏感性高,需要削减人口。

Regionalization of Urban Population Growth Control Based on Suitability Level for Human Settlements:A Case Study of Nanjing City

The optimized allocation of population distribution should not only consider the cost and revenue of Population aggregation,but also should pay attention to the restriction and suitability level of human settlements.First,by building the revenue function and external cost function of population,this paper analyzed the optimal population for the central city,suburb area and county area of Nanjing city.Then by using random and objective function based on evaluation for the suitability level of human settlemen...
