Adding analysis of urban heat island effect in GIS system and applying them in urban planning

In recent years, the application of GIS in urban planning has attracted the attention of more and more urban planning designers, and a new problem— urban heat island has arose in urban planning .The main aim of the paper is to find ways to connect urban heat environment with GIS system, and to simulate different island effect of different urban planning by using CFD. Then find a reasonable way for ecological urban planning .Of course, we firstly introduce the relation between the City Heat Island Effect and urban planning, then enumerate a practical experiment of Chongqing University. Because of people''s requirement of the better living environment and the ecological development of the whole city even the whole globe, we should synthesize and analyze the practical information, which base on the natural factors such as earth surface environment, climate, rainfall amount and wind field, and with these artificial factors such as population, politics and cultures, then design the optimum project of urban planning.
