鄂尔多斯地区城市热岛效应初步分析

在针对鄂尔多斯地区的城市热岛效应的研究时发现,找到没有受到人为干扰的站点十分困难,于是本文使用了相对的概念,即是受到人为干扰较少的站点作为对比站点。通过对近50年的气温数据资料,本文发现鄂尔多斯地区年相对城市热岛强度在1.2℃左右,春季的相对城市热岛强度最弱,冬季的最强。本文将发展较为缓慢的1961年—1990年30年划分为一个年代,发展相对快速的1991年—2010年20年划分为一个年代,发现鄂尔多斯地区热岛效应有所增强,但夏季有所减弱,春秋两季加强明显。

Preliminary Analysis of Urban Heat Island Effect in Ordos

We found that it is very difficult to seek out the stations which without man-made distraction when we research the urban heat land effect in the area of Ordos. In this study, we use the relative conception that is taking the stations with litter mind-made distraction as contrastive stations. According to the temperature data nearly 50 years, we found the annual relative urban heat island intensity is about 1.2℃ in Ordos, in spring it＇s the lowest, in winter it＇s the highest, in this study, we take 30 years from 1961 to 1990 that developed very slowly as an age, and 20 years from 1991 to 2010 that developed very rapidly as another age, we can get the result that the urban heat land effect in Ordos enhanced, but in summer it weakened, in spring and autumn it enhanced obviously.
