Abstract
The rapid urbanization of Chinese cities has resulted in significant effects to the urban environment and to urban ecological networks. Zhengzhou city, the capital city of Henan province in central China, is characterized by a warm climate and four distinctive seasons, with a dry spring, and a hot and rainy summer. Based on satellite images, we analyzed land surface temperature (LST) and prepared a further assessment. Using LST data, we analyzed the urban heat island (UHI) and its relationship to green space, in order to make suggestions for future urban planning. The results show that urban heat island exists in Zhengzhou city Central Urban area. The mean land surface temperature (MLST) difference between urban and non-urban is significant. In addition, the urban green space reveals a negative relationship with LST. To conclude, we discuss the role of green space in mitigating urban heat island and propose some greenway related strategies for urban landscape planning in Zhengzhou city.
