Today, in our environmental science lecture, we'll discuss the impact of urban green spaces. A recent study in Manchester found that increasing tree coverage by 10% could reduce surface temperatures by up to 2.5 degrees Celsius during heatwaves. However, the researchers noted that the effect varies depending on tree species and local wind patterns. They also emphasized that green roofs, while beneficial for insulation, have a smaller cooling effect on street level compared to parks. Interestingly, the study suggested that small, scattered green areas are more effective for cooling than one large park, because they allow better air circulation. This finding challenges previous assumptions in urban planning.
❓ Según la conferencia, ¿qué reveló el estudio en Mánchester sobre los espacios verdes urbanos?
A. A. Los parques grandes enfrían la ciudad de manera más efectiva que las áreas verdes pequeñas.
B. B. Aumentar la cobertura arbórea en un 10% puede reducir las temperaturas hasta en 2,5 grados Celsius.
C. C. Los techos verdes tienen el mayor efecto de enfriamiento a nivel de calle.
D. D. El efecto de enfriamiento de los árboles es independiente de los patrones de viento locales.
✅ 正确答案
B. Increasing tree coverage by 10% can lower temperatures by up to 2.5 degrees Celsius.
