Today, in our environmental science lecture, we'll discuss urban green spaces. A recent study in Melbourne found that parks can reduce local temperatures by up to four degrees Celsius during heatwaves. However, the cooling effect depends on tree canopy coverage, not just grass areas. The researchers also noted that residents living within 300 meters of a large park reported better mental health. Interestingly, smaller pocket parks had less impact on temperature but were more accessible for daily walks. So, when designing sustainable cities, planners should prioritize a network of varied green areas rather than a single large park.
❓ 講義によると、メルボルンの研究は大規模な公園について何を明らかにしましたか？
A. それらは小さな公園よりも気温を下げる効果が高い。
B. 樹木の被覆が十分な場合にのみ、冷却効果が発揮されます。
C. それらは、ポケットパークよりも精神的健康に有益ではない。
D. それらは常に住宅地から300メートル以内に位置しています。
✅ 正确答案
They have a cooling effect only when tree coverage is sufficient.
