Study on Urban Thermal Environment Based on RS and GIS Techniques-Taking as Example in Coastal Cities of Southeast Fujian Province

摘要

In this paper, coastal cities of southeast Fujian Province were taken as study area to evaluate the thermal environment and analyze the characteristic of spatial thermal pattern after established the thermal environment comprehensive evaluation model with the indices extracted from multi-data considering the impact of natural and human factors. And the spatial-temporal patterns of urban thermal environment comprehensive geo-information .A series of maps were built so as to explore the deeper information of urban thermal environment on regional scale. This work was the application of geoinformation to the field of urban thermal environment which has certain significance to the sustainable development of cities.
