Today in our environmental science lecture, we're discussing urban green spaces. A recent study in Melbourne found that increasing tree coverage by just 10% can reduce local temperatures by up to 2 degrees Celsius during summer heatwaves. However, the researchers noted that the effect varies depending on tree species and placement. For example, deciduous trees planted on the western side of buildings provide shade in the afternoon, while evergreen trees are more effective for windbreaks in winter. Interestingly, the study also highlighted that parks with a mix of grass and trees had higher biodiversity than those with only trees. So, when designing sustainable cities, we must consider both thermal benefits and ecological impacts.
❓ Según la conferencia, ¿qué encontró el estudio en Melbourne sobre aumentar la cobertura arbórea en un 10%?
A. A. Reduce las temperaturas locales en 2 grados Celsius en todas las estaciones.
B. B. Es más efectivo cuando los árboles se plantan en el lado este de los edificios.
C. C. Puede reducir las temperaturas locales hasta en 2 grados durante las olas de calor del verano.
D. D. Conduce a una mayor biodiversidad que los parques que solo tienen césped.
✅ 正确答案
C. It can lower local temperatures by up to 2 degrees during summer heatwaves.
