| 摘 要： | 随着城市的快速发展,城市热岛效应越来越重要。本文利用环境卫星数据,以西安市和兰州市为例,通过对河谷与平原城市的热岛效应差异进行初探,发现在两个研究区的市区内部,其热岛分布特征与已有研究的热岛分布特征一致。但就整个研究区而言,西安市的热岛主要分布在城区,兰州市则主要分布在郊区。分别对西安和兰州的地表温度与NDVI进行了相关性分析,发现西安市的地表温度与水体指数呈非线性相关,而兰州市则呈线性相关。

Analysis the Difference of Urban Heat Island between the Valley City and the Plain City |

| Abstract: | With the rapid development of the city,the urban heat island has been more and more important.Based on environmental satellite data and taken the Xi'an and Lanzhou city as an example.Comparing the difference of the heat island between the valley city and the plain city,we found that the distribution characteristics of the two studying urban areas match with the existing research.But in terms of the studying area,the heat island of Xi'an city is mainly in urban areas,and Lanzhou city is mainly in the suburbs.Through the correlation analysis between surface temperature and NDVI in Xi'an and Lanzhou city,the surface temperature and NDVI is non-linear correlation in Xi'an city,but Lanzhou city is linear correlation. |
