| 摘 要： | 以深圳特区为例,利用2005年11月份的TM和Quickbird影像数据,在进行地表温度反演和城市绿地详细解译的基础上,研究了城市绿地类型、属性特征与地表热环境分异之间的关系.研究结果显示,城市绿地不同类型的地表温度差异较大,各类人工绿地的地表温度普遍高于自然绿地类型.分样区平均NDVI和聚集度指数与热岛强度指数之间呈显著的正相关关系,而均匀度和碎裂化指数则与热岛强度指数之间呈显著的负相关关系.上述结果表明,城市绿地的类型、结构及其格局特征均对城市热环境空间分异具有显著影响,在城市绿地建设工作中,应充分重视绿地景观的这种热环境效应特征的指导意义,以期使城市绿地建设能够更好地担负其必要的生态服务功能.

| Abstract: | This paper took Shenzhen Special Economic Zone as an example,using the TM and Quickbird images of Shenzhen in November 2005,and further inversion of surface temperature and manual interpretation of urban green space based on them,discussed the relationship between the types,attribute characteristics of urban green space and the spatial differentiation of urban thermal environment.The results show that the land surface temperature differed in green space types,and the artificial green space was generally hig... |
