The phenomenon of urban heat islands (UHIs) has garnered significant attention in climate research due to its implications for energy consumption and public health. UHIs occur when metropolitan areas experience higher temperatures than their rural surroundings, primarily because of the prevalence of heat-absorbing materials like concrete and asphalt, coupled with reduced vegetation cover. Recent studies suggest that the intensity of UHIs can be mitigated through strategic urban planning, such as the incorporation of green roofs and reflective pavements. However, the effectiveness of these interventions varies with local climate conditions and urban density, necessitating tailored approaches rather than one-size-fits-all solutions. Furthermore, while mitigation efforts focus on temperature reduction, they also contribute to improved air quality and enhanced thermal comfort for residents, thereby addressing multiple urban challenges simultaneously.
❓ What does the passage suggest about urban heat island mitigation strategies?
A. A) They are universally effective regardless of local conditions.
B. B) They primarily aim to reduce energy consumption rather than temperature.
C. C) Their success depends on site-specific factors like climate and density.
D. D) They have no additional benefits beyond temperature reduction.
✅ 正确答案
C) Their success depends on site-specific factors like climate and density.
