摘要
城市化水平体现着社会经济发展水平,是现代化的核心内容和标志之一,对各地区的城市化水平进行科学的预测,具有重要的现实意义。利用生物学的异速生长规律,从城市人口和城市用地这两个角度进行探讨,并以西安市进行实例研究,描述和分析人口、用地的异速增长关系和规律,建立城市化水平测算模型,并得出西安市城市人口-城区面积亦适用异速生长关系,且人-地关系状态较好。从而基于异速生长关系进行城市化水平测算,最后进一步探讨该模型的其他应用。
It is of realistic significance to forecast th e urbanization level of different areas. This paper, applying the allometric growth law of biology and taking Xi'an City as a case study, discusses and analyzes the allometric growth law of population and land, establishes a measurement model of urbanization level of the city, concluding that the population and acreage of Xi' an City agree with allometric growth relationship and that the relationship between people and land has been relatively good.
