陕西省城市人口与城市用地异速生长关系研究

Allometric Growth Relationships between Urban Area and Population in Shanxi Province

通过构建异速生长模型,探讨陕西省城市人口增长与城市用地扩张相互之间的关系.结果表明,从2001年到2010年,陕西省城市人地关系呈负异速生长关系,城市用地扩张整体上处于不合理的水平,其中西安、宝鸡和咸阳等关中地区城市用地扩张速度最快,其异速生长系数远远超过了临界值,在以后的城市规划中应加强针对性的调控.

The relationship between urban population growth and urban land expansion in Shanxi province was discussed by constructing the model of allometric growth.The results showed that the relationship between urban population and urban land is negative allometric growth during 2001 to 2010,and the expansion of urban land is in an unreasonable level.The urban land expansion speeds of Xi’an,Baoji and Xianyang in Guanzhong Land are fastest,and their allometry coefficients are far more than the critical value,so the pertinence control should be strengthened in the later urban planning.
