摘要

绿色基础设施(GI)的降温效应正成为缓解城市热岛效应的热门话题。绿地改造是降低地表温度的可行解决方案,但很少有研究为适应不同地区的景观规划提供具体指导。本文提出并定义了景观复杂性和降温效应阈值。结果表明:(1)GI在建筑密集区的降温效果优于绿化带;(2) GI具有简单的形式、聚集的配置和低贴片密度,具有更好的冷却强度;(3) 在建筑密集区,森林区的TVoE为4.5公顷,而在绿化带,森林和草原区的TVo E分别为9公顷和2.25公顷。这些结论将有助于规划者有效地减少LST,并采用环境可持续规划。

THE COOLING INTENSITY DEPENDENT ON LANDSCAPE COMPLEXITY OF GREEN INFRASTRUCTURE IN THE METROPOLITAN AREA
The cooling effect of green infrastructure (GI) is becoming a hot topic on mitigating the urban heat island (UHI) effect. Alterations to the green space are a viable solution for reducing land surface temperature (LST), yet few studies provide specific guidance for landscape planning adapted to the different regions. This paper proposed and defined the landscape complexity and the threshold value of cooling effect (TVoE). Results find that: (1) GI provides a better cooling effect in the densely built-up area than the green belt; (2) GI with a simple form, aggregated configuration, and low patch density had a better cooling intensity; (3) In the densely built-up area, TVoE of the forest area is 4.5 ha, while in the green belt, TVoE of the forest and grassland area is 9 ha and 2.25 ha. These conclusions will help the planners to reduce LST effectively, and employ environmentally sustainable planning.
