Today, in our environmental science lecture, we'll discuss urban heat islands. As you know, cities tend to be warmer than surrounding rural areas due to concrete and asphalt absorbing heat. However, one effective mitigation strategy is increasing green spaces, such as parks and green roofs. A recent study in Melbourne found that adding tree canopy can reduce surface temperatures by up to 8 degrees Celsius. But, interestingly, the study also noted that the cooling effect is strongest within 100 meters of the green area. Therefore, planners should distribute small parks throughout neighborhoods rather than concentrating them in one large central park.

A. A. 수관층은 모든 곳에서 기온을 최대 8도까지 낮출 수 있습니다.
B. B. 냉각 효과는 녹지로부터 100미터 이내에서 가장 두드러진다.
C. C. 대규모 중앙 공원이 소규모 분산 공원보다 더 효과적이다.
D. D. 녹색 지붕은 나무 캐노피보다 열을 줄이는 데 더 효과적입니다.
✅ 正确答案
B. The cooling effect is most significant within 100 meters of the green area.
