Today in our environmental science lecture, we're discussing urban green spaces. A recent study in Melbourne found that parks and community gardens can reduce local temperatures by up to 3 degrees Celsius during heatwaves. However, the key factor is not the size of the green area, but its connectivity. Fragmented patches of greenery, even if large, are less effective than a network of small, interconnected gardens. This is because connected spaces allow better air flow and provide corridors for wildlife, which in turn helps maintain soil moisture and plant health. The study suggests that city planners should prioritize creating green corridors between existing parks, rather than focusing solely on expanding single large parks.
❓ 강의에 따르면, 멜버른에서의 연구는 도시 녹지 공간에 대해 무엇을 밝혀냈습니까?
A. A) 대형 공원은 소규모 정원보다 열을 줄이는 데 더 효과적이다.
B. B) 녹지 공간의 효과는 주로 그 연결성에 달려 있다.
C. C) 멜버른의 폭염은 단편화된 녹지로 인해 더욱 빈번해지고 있다.
D. D) 도시 계획자들은 더 나은 냉각 효과를 위해 크고 고립된 공원을 조성하는 데 집중해야 한다.
✅ 正确答案
B) The effectiveness of green spaces depends mainly on their interconnectedness.
