基于遥感和GIS的上海城市空间热环境研究

城市热环境的空间格局对城市微气候、城市生态环境演变有重要影响。为探讨城市热环境空间格局的研究方法,借鉴景观生态学的研究方法,首次提出热力景观概念,以景观的观点来研究城市热环境的空间格局。在RS,GIS的支持下,创建了热力景观空间格局的评价指标体系。应用转移矩阵法对1990年,1995年和1998年上海城市多时相热力景观的转移概率进行,分析了热力景观的动态变化和热力景观类型的组分转换过程。通过分析,揭示了上海城市近10年热力景观类型的变化强度和趋势。

Research on Spatial Thermal Environment in Shanghai City Based on Remote Sensing and GIS

Spatial thermal environment has a full impact on microclimate and urban zoology. The aim for this paper is to seek a effective method to analyse spatial pattern of thermal environment. The concept of "thermodynamic landscape" was presented for first time in this paper. The viewpoint of "thermodynamic landscape" to analyse spatial pattern of urban heat environment was presented using the landscape ecosystem for reference. An estimation system for spatial pattern of "thermodynamic landscape" was developed with GIS, RS supporting. The authors studied the dynamic evolvement of "thermal landscape" & its change process based on change matrix of multi-temporal "thermal landscape" in Shanghai in 1990,1995,1998. The change intension and trend of "thermal landscape" was pointed out in the city during last decade in this paper.
