【摘要】 为了解决城市热岛效应对城市生态环境的影响问题,通过对北京市近3年地表温度和热岛强度反演,揭示了北京市空间热环境的时空演变规律,在此基础上,对城市道路系统、绿化带和水系与空间热环境的关系进行了详尽的研究。结果证明,城市廊道系统对城市空间热环境有明显的影响,但影响范围一般不会超过300m,这一结论对城市廊道系统的规划具有重要的指导意义。更多还原

【Abstract】 Through various studies,the ambient temperatures of numerous urban centers have been determined to be several degrees higher than the ambient air temperatures of surrounding rural areas.By computing the land temperature and UHI intensity in 2001,2002 and 2004,authors describe the spatial-temporal evolution patterns of spatial heat environment in Beijing.Based on all the above,the relationship between UHI intensity and road system,shelter belt and water system have been studied in detail.The results prove that the allure structure system have influenced the mini-climate of the city.But the affected range is less than 300 meters.This conclusion has an important guidance meaning to city programming of allure system structure.更多还原
