概括
由于安全和财产问题,野火指挥官经常选择完全镇压. 这项研究揭示了影响灭火决策的因素,强调需要考虑管理背景以及环境因素,以有效应对野火.
科学领域:
- 野生林火灾管理 野生林火灾管理
- 生态恢复 生态恢复
- 环境社会学环境社会学
背景情况:
- 野火事件指挥官在复杂的社会环境中工作.
- 决策受到安全,财产保护,公众压力和代理文化的影响,通常有利于完全压制.
- 为了安全,降低成本和生态效益,存在诸如点区域保护,封闭/封闭和维护/监控等替代策略.
研究的目的:
- 确定与完全抑制相比较的管理,社会经济,环境和火灾行为特征,与不完全抑制策略相比.
- 了解影响野火响应决策的因素,由事件指挥官做出.
主要方法:
- 事件报告数据的分析来自美国北方落基山脉的374场野火 (2008-2013).
- 应用回归模型来将野火特征与灭火策略相关联.
- 从与指挥官的采访中获得的定性数据,为定量发现提供背景.
主要成果:
- 完全镇压与较高的住房密度,较早的日历日期,非联邦土地管辖权和使用区域/国家事件管理团队密切相关.
- 与完全抑制相关的其他因素包括人为点火,火灾增长潜力低,火灾大小更大.

Ecological Disturbance
17.1K
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.

Fundamental Attribution Error

According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

Bystander Effect
9.6K
The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

Applications of GIS: Disaster Management and Emergency Response
87
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...

Threats to Biodiversity
22.3K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
