无透覆盖变化作为环境公平指标
概括
在2001-2019年间,不透气覆盖 (IC) 的增加不成比例地影响了少数群体. 这些社区并不一定是贫穷的,受教育程度较低的,或说不英语的,这突出了复杂的环境公平模式.
科学领域:
- 环境科学 环境科学
- 城市规划 城市规划
- 社会科学 社会科学 社会科学
背景情况:
- 环境公平研究通常使用高分辨率数据,限制时间分析.
- 环境灾害的时间监测是当前研究中的一个缺口.
- 无透覆盖 (IC) 是一个与社会经济地位 (SES) 相关的关键环境不良.
研究的目的:
- 检查IC和人口统计学属性之间的时间关系在整个美国 (2001-2019) 期间.
- 在以模式为重点的环境公平研究中解决时间监测的差距.
主要方法:
- 利用中等分辨率的遥感数据,在全国范围内评估时间IC变化.
- 验证了24个城市的中分辨率IC数据与高分辨率数据,计算了平均绝对偏差 (MAD).
- 分析了IC增加和人口因素之间的相关性.
主要成果:
- 从2001年到2019年,发现IC的普遍增加,特别是在少数群体中.
- 观察到,这些IC增加的社区并不一定是贫困,低教育或非英语人口的特点.
- 证实了中等分辨率IC数据的可靠性,与高分辨率数据相比,平均MAD为4.8%.
结论:
- 不透气覆盖的暂时增加对少数群体产生了不成比例的影响.
- 环境负担不仅集中在社会经济弱势地区,这表明了复杂的环境正义动态.
- 中等分辨率数据是时间环境公平研究的可行工具.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
26
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Global Climate Change
23.9K
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.

Ecological Disturbance
16.8K
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

Environmental Influences on Intelligence
125
Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...
