摘要

自然栖息地的丧失和人类活动的增加导致城市气温升高,生物多样性减少。人们提出了垂直绿化系统(VGSs)来缓解气温升高和生物多样性的丧失。迄今为止,对现有垂直绿化系统的研究只分析了单一的生态系统服务,还没有将其性能与其自然同类系统进行比较。在此,我们对新加坡建筑物上两种不同类型的现有 VGS(攀缘植物、叶片)进行了空气和表面温度测量以及生物多样性观测,并将其与无植被的建筑物墙壁和有植被的自然悬崖进行了比较。我们的研究结果表明,VGS 起到了温度缓冲作用,在白天向建筑墙壁形成冷却层,在夜间形成温暖层。此外,VGS 容纳的动物明显多于无植被墙壁,但 VGS 容纳的动物却少于有植被的天然悬崖。此外,研究还发现,周围植被的数量(绿色覆盖率、VGS 10 米范围内的树木密度)、植被的厚度、VGS 上植物的丰富程度与 VGS 上观察到的生物多样性之间存在正相关。总之,在新加坡这样的热带城市,VGS 不仅可以美化环境,还可以用来调节白天的温度,至少可以部分缓解生物多样性栖息地的丧失。

Rocks and walls: Biodiversity and temperature regulation of natural cliffs and vertical greenery systems

Rocks and walls: Biodiversity and temperature regulation of natural cliffs and vertical greenery systems
Loss of natural habitats and increased human activity results in warming up of cities and a reduced biodiversity. Vertical greenery systems (VGSs) have been proposed to mitigate rising temperatures and the loss of biodiversity. So far, studies on existing VGSs have only analysed a single ecosystem service and their performance has not been compared to that of their natural counterparts. Here, air and surface temperature measurements as well as biodiversity observations were conducted on two different types of existing VGSs (climber, foliage) on buildings in Singapore and compared to non-vegetated building walls and vegetated natural cliffs. Our results show that VGSs act as temperature buffer creating a cooling layer towards the building wall during the day and a warming layer during the night. Furthermore, VGSs host significantly more animals than non-vegetated walls, however, VGS have less animals than vegetated natural cliffs. Moreover, a positive correlation was found between the amount of surrounding vegetation (green cover, tree density within 10 m of VGS), thickness of vegetation, plant richness on VGS and biodiversity observed on VGSs. Together, VGSs not only contribute with their aesthetics but can also be used to regulate daytime temperature in a tropical city like Singapore and to mitigate, at least in part, the loss of habitat for biodiversity.
