世界遗产城市地区空间变迁探析

Space Evolution of the World Hegitage City Regions

该文在国家历史文化名城相关研究的基础之上研究世界遗产城市地区空间变迁:土地利用,在对国际上土地利用相关研究综述之后,概要介绍了世界遗产城市及其历史时期空间变迁;然后,从土地利用历史断面的角度出发,研究了近300年来各时期世界遗产城市地区的土地覆盖特征,以及从土地利用历史路径的角度出发,具体阐述世界遗产城市地区土地覆盖特征所形成的过程,得出的结论主要包括:近300年世界遗产城市地区人口发展和土地开发在总量增加的同时也伴随了世界性的迁移,这一阶段世界遗产城市地区主导土地覆盖类型大部分都转变为农业或半农业,这种变化尤其体现在20世纪当中;最后,文章初步比较了世界遗产城市地区与国家历史文化名城地区的空间变迁情况,得出的结论主要包括:世界遗产城市地区以及国家历史文化名城地区在这一阶段的土地利用都发生了根本性的转变,前者更多是一种外延式增长,而后者更多是一种内生式增长,土地利用向农业和半农业的转变,国家历史文化名城地区要比世界遗产城市地区早大概两个世纪。

This paper studies land use, one of the space evolution factors of the world heritage city regions based on the research achievement of national history city regions. The related works on the research of land use are summarized at first. Then, the history space evolution of the world heritage city regions are introduced briefly. Next, we explore the land use characteristics of the world heritage cities over recent three centuries based on the land use historical section, and analyze how these characteristics have developed by observing the land use historical trajectories,from which the author shows that in the past three centuries, the population growth and land development in the total amount increasement in theworld heritage city regions was accompanied by a worldwide migration. During this period, the majority of world heritage cities＇ land-cover types were transformed to agricultural or semi-agriculture, and this change is especially seen in the recent 100 years. Finnally, a comparative study between the world heritage city regions and the national history city regions is conveyed, from which the author show that the land use in the world heritage cities and the national history cities＇ land use have undergone a fundamental change over the past three centtLries; the former is a more extensional growth, while the latter more of endogenous growth, which is the land use to agricultural or semi-agricultural changes. The former is two centuries earlier than the latter.
