概括
绿色和蓝色空间 (GBS) 可以减少与热有关的死亡,森林和河流提供了最大的保护. 维护和扩大这些空间对公共卫生至关重要,特别是因为气候变化加剧了热风险.
科学领域:
- 环境流行病学环境流行病学
- 城市规划是城市规划.
- 公共卫生 公共卫生
背景情况:
- 绿色和蓝色空间 (GBS) 被认为可以减少与热有关的健康问题.
- 很少有研究研究了特定GBS类型的变化如何影响与热有关的死亡率.
研究的目的:
- 分析不同GBS类型如何改变与热有关的死亡风险.
- 根据各种GBS情景来估计死亡负担的变化.
主要方法:
- 一个案例时间序列研究使用了来自1085个中国分区 (2009-2020) 的每日死亡率和温度数据.
- 使用人口密度,GBS边界和街景图像来评估GBS暴露.
- 使用有条件波桑回归的分布式滞后非线性模型来分析类型特定的GBS效应.
主要成果:
- 对森林,公园,自然保护区,街道绿化,湖泊和河流的更高暴露与较低的与热有关的死亡风险相关.
- 增加30%的绿色空间暴露可以防止4.8%的与热有关的死亡;类似增加的蓝色空间可以防止16.2%.
- 相反,GBS暴露量减少30%会使与热有关的死亡率增加4.8% (绿色) 和15.9% (蓝色).
结论:
- 不同的GBS类型在减轻与热有关的死亡率方面的有效性各不相同.

Lung Capacity
49.1K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Global Climate Change
24.1K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Radiation: Applications
1.1K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.

Responses to Heat and Cold Stress
13.3K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
