城镇化背景下南充市城市扩张合理性评价
|
摘要
为了解当前新型城镇化背景下城市扩张的系统合理性,以川东北中心城市南充市为例,选取12个指标构建城市扩张合理性综合评价体系,运用熵值法确定指标权重,获取合理性综合指数,再引入协调系数,获取南充市城市扩张合理性结果。结果表明:(1)2007—2016年南充市城市扩张的合理性综合指数由0.064上升至0.946,合理性增强;(2)各个子系统之间的关系经历了"不协调-基本协调-协调"的变化趋势,表明南充市城市扩张系统合理,基本符合该城市发展的承载力水平。
To understand the systematic rationality of urban expansion under the background of new-type urbanization at present,this paper takes Nanchong City which is located in the Northeast of Sichuan as an example to build the comprehensive rationality evaluation system of urban expansion by 12 indicators.Entropy evaluation method is used to determine the indicator's weight and acquire rationality's comprehensive index.Nanchong's urban expansion rationality is finally acquired by introducing coordination coefficient.The result shows:(1) The rationality composite index of Nanchong's urban expansion had increased from 0.064 of 2007 to 0.946 of 2016,suggesting its enhanced rationality;(2) The relationship between the three subsystems had experienced a change trend of "disharmony-basic harmony-harmony",revealing the rationality of Nanchong's urban expansion and its consistence with Nanchong's bearing capacity.It is proposed that the potentialities of land should be further exploited in Nanchong's future development,and the same emphasis should be laid on scale expansion and city quality.
