Influence of land use/cover change on land surface temperature of Laizhou Bay plain

摘要

Many costal regions in China are confronted with challenging problems of limited land resources and increasing population. Saline lands, tidelands and wetlands have been enclosed for agricultural land uses and urbanization buffer zones under a series of reclamation programs. A combined approach of remote sensing (RS) and geographical information system (GIS) was used in this study to identify the impact on Land Surface Temperature (LST) due to land use/cover change. We analyzed the impacts of LUCC (Land Use and Land Cover Change) on LST in Laizou Bay plain in different years. The results showed that land use types of culturing water increased significantly, correspondingly the area of grass land and salt land have a substantial reduction, and that of urban and rural settlements increased considerably . We retrieved the land surface temperature of two years using the method of Qin Zhihao's mono-windows algorithm. Then we analyzed the temperature change on different kinds of land use. We find different types of land usehave different responses on temperature change. To sum up, there are strong correlations between LUC and LST.
