Today in our environmental science lecture, we're discussing urban green spaces. A recent study in Melbourne found that increasing tree canopy coverage by just 10% can reduce local temperatures by up to 2.5 degrees Celsius during summer heatwaves. This happens because trees provide shade and release moisture through transpiration. However, the researchers noted that the effect is strongest in residential areas with low-rise buildings, rather than in city centers with tall structures that block air flow. The study also highlighted that parks with diverse native plant species attract more pollinators, which benefits nearby community gardens. So, when planning new housing developments, incorporating green corridors is crucial for both climate resilience and biodiversity.
❓ Según la conferencia, ¿qué encontró el estudio en Melbourne sobre un aumento del 10% en la copa de los árboles?
A. Reduce las temperaturas en aproximadamente 2.5 grados Celsius en todas las áreas urbanas.
B. Tiene el mayor efecto de enfriamiento en áreas residenciales con edificios de poca altura.
C. Solo ayuda si los parques contienen especies de plantas nativas.
D. Aumenta significativamente los niveles de humedad durante las olas de calor.
✅ 正确答案
It has the greatest cooling effect in residential areas with low-rise buildings.
