科学领域:
- 环境科学
- 城市规划
- 抗灾能力
背景情况:
- 极端天气事件造成重大破坏,经济损失和流离失所.
- 邻里地区的恢复能力有所不同,灾后可能会分段撤离或加强.
- 之前的回收评估使用了聚合数据,限制了细分分析.
研究的目的:
- 分析极端天气事件后的社区建筑环境恢复.
- 研究不同社会经济群体的复苏轨迹的差异.
- 确定导致社区对灾难作出不平等反应的因素.
主要方法:
- 使用街景图像和多式机器学习构建了建筑级别的灾难恢复数据集.

Ecological Disturbance
20.6K
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.

Masonry in Cold and Hot Weather Conditions
303
In cold weather, masonry construction requires specific precautions to ensure mortar does not freeze before curing, as this can significantly weaken its strength and watertightness. Mortar temperature should be maintained between 60°F and 80°F to support proper hydration and curing. Below 40°F, mortar water must be heated, but should not exceed 120°F as high temperatures can reduce mortar's compressive and bond strength.

Applications of GIS: Disaster Management and Emergency Response
413
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...
