Study on urban heat island of Lianyungang based on remote sensing
2011
The MODIS land surface temperature data were used to analysis the temporal and spatial characteristics of heat island of
Lianyungang. Based on preprocessing data, this paper mainly discuss the relationship between urban heat island and its
ground, vegetation, illumination and man-made features, specifically analyze the influences of these factors to urban heat
island in Lianyungang. The results showed that: the city heat island has a close relationship with the degree of the
urbanization (city buildings, population number, population density, industry development, transportation, and so on),
geographic conditions, human activity manner, etc.; and the urban heat island intensity is strongest at autumn and winter,
weakest at summer. Finally, we give some suggestions about heat island and building a technical system for
Lianyungang's future developing.
