摘　　要：从空间支撑性的角度比较研究世界遗产城市与国家历史文化名城地区环境背景,选取的环境背景要素是归一化植被指数,在对两类遗产城市地区归一化植被指数分别进行研究的基础之上,比较了两者的异同,得出的主要结论包括:从世界遗产城市与国家历史文化名城地区各地域年归一化植被指数算术平均值的比较来看,以60km研究半径为分界点,在小于60km区间前者植被情况整体高于后者,而在60km-200km区间后者植被情况整体高于前者,且世界遗产城市各地域年归一化植被指数分布更为离散,国家历史文化名城地区各地域年归一化植被指数分布更为集中。This paper studies normalized difference vegetation index （NDVI） , one of the environmental background factors of the heritage city regions, from the perspective of space carrying, The related work on the research of NDVI is summarized at first. Then, we give a NDVI description of the world heritage city regions and the national history city regions. The primary conclusions of this research include ： the NDVI in the world heritage city regions is higher than that in the national history city regions when the studied regional radius is from 20kin to 60km, and the NDVI in the national history city regions is higher than that in the world heritage city regions when the studied regional radius is from 60km to 200kin; the NDVI of the World Heritage city regions is more discrete, and the NDVI of the national history city regions is more concentrated.
