摘要
对世界遗产城市与国家历史文化名城地区的降水情况进行比较研究,以期从水资源的视角对我国的基本国情有所了解,得出的主要结论包括:就城市地区中心点降水的整体情况而言,国家历史文化名城比世界遗产城市相对丰富且极端;从城市地区各地域降水情况的比较来看,世界遗产城市均值基本维持在840 mm左右,而国家历史文化名城地区则在930 mm左右,且前者各地域年降水总量的分布更为集中,后者各地域年降水总量的分布更为离散。同时也说明:对于城市地区各地域降水而言,国家历史文化名城降水呈现多样性的类型集聚特征。
Heritage city is the space scale brief history of human civilization. Under a comparative study of the precipitation about world heritage cities and national historical and cultural cities, main following conclusions are summarized to understand China＇s basic national condition from the perspective of water resources. On the over- all precipitation situation of center urban areas, national historical and cultural cities are relatively richer and extremer than world heritage cities. From the comparison of the precipitation in different regions of urban areas, world heritage cities mean basically maintain at about 840 mm, and national historical and cultural cities are at about 930 ram. National historical and cultural cities with distribution of annual total precipitation are more con- centrated than world heritage cities. National historical and cultural cities are relatively richer and extremer than world heritage cities in the regional precipitation of urban areas.
