摘要
土地覆盖的变化被认为是造成城市热岛现象的主要因素。城市热岛是当地气候变化的一种形式,其特点是与城市郊区的植被区相比,城市中心区的气温升高达 6 摄氏度。紧凑的植被地或绿色开放空间(GOS),能够避免周围温度升高。GOR H. Agus Salim 作为巴东市的 GOS 之一,是居民休闲娱乐的场所,他们可以与朋友和家人一起享受各种美食,还可以进行体育活动,从而充实自己的空闲时间。本研究旨在衡量树冠对改善 H. Agus Salim GOR 地区气候的益处。研究于 2023 年 9 月进行,在 5 个测量点(3 个在树冠下,2 个在空地上)重复 7 次。数据是用温湿度计直接在田间测量的。采用树荫下和空地测量的差异法分析树木提供的降温效果。热舒适度使用经验公式温度湿度指数(THI)进行测量。结果显示,树下的温度从 2.0 摄氏度(上午)下降到 2.9 摄氏度(下午)。然而,THI 计算显示,GOR H. Agus Salim 在树冠下和空地上都处于不舒适标准。
Thermal Comfort Level and the Ability of Trees to Reduce Temperature at H. Agus Salim Sports Hall, Padang City
Changes in land cover are thought to be the main factor in the Urban Heat Island (UHI) phenomenon. UHI is a form of local climate change which is characterized by an increase in temperature reaching 6oC in central urban areas compared to vegetated areas on the outskirts of the city. Compact vegetated land or Green Open Space (GOS), which is able to avoid increasing the surrounding temperature. GOR H. Agus Salim as one of the GOS in Padang City is a place for residents to have recreation and fill their free time by enjoying various culinary delights with friends and family as well as sports activities. This research aims to measure the benefits of tree canopies as climate amelioration in the H. Agus Salim GOR area. The research was conducted in September 2023, with 7 repetitions at 5 measurement points (3 under the tree canopy and 2 in the open field). Data is measured directly in the field with a thermohygrometer. The cooling effect provided by trees was analyzed using a difference approach between measurements in shade and open areas. Thermal comfort level is measured using the empirical formula Temperature Humidity Index (THI). The results showed that there was a decrease in temperature under the tree from 2,0oC (in the morning) to 2,9C (in the afternoon). However, THI calculations show that GOR H. Agus Salim is in the Uncomfortable criteria both under a canopy and in open areas.
