| 摘要: |
| 为探讨湿冷城市老人冬季户外活动如何适应休憩场地微气候，本研究于2016年和2017年冬季对冬季典型湿冷气候城市——成都市进行现场观察和微气候参数测量，结合TS-Givoni指标和微气候参数讨论老人户外休憩中在时间和地点等方面的微气候适应性选择。研究发现：当TS＜2.0℃时，老人无户外休憩活动，当TS值≥2.1℃时，老人户外休憩不受空间和时间限制；当2.0℃≤TS值＜2.1℃时，老人户外休憩主要适应风速和太阳辐射照度而选择休憩时间和休憩地点。研究结果可为冬季湿冷气候城市户外适老休憩空间的规划设计提供理论依据和技术参考。 |

| Abstract: |
| To explore how the urban elderly adapt to the microclimate in outdoor recreation activities in winter, we launched field observations and measurement of microclimate parameters in Chengdu, a typical cold and wet city in winter of 2016 and 2017. We applied the TS-Givoni index and microclimate parameters to discuss how the old people choose the time and sites of outdoor recreation to adapt to the microclimate. The results show that the old people abandoned outdoor recreation as TS value＜2.0℃; they chose recreation sites and time freely as the TS value≥2.1℃; and they chose the sites and time to adapt to the wind speed and solar radiation as 2.0≤TS＜2.1℃. The results could be applied as a theoretical basis and technical reference in the design of outdoor recreation sites for the elderly in cold and wet cities in winter. |
