概括
在明尼阿波利斯-圣保罗地区,城市树木的多样性各不相同,少数主导物种增加了对气候变化的脆弱性. 这种多样性与社会经济因素无关,但在某些地区,高气候和社会脆弱性重叠.
科学领域:
- 城市林业城市林业
- 生态生态学 生态生态学
- 环境正义 环境正义
背景情况:
- 城市树冠覆盖面分布不均,在社会脆弱的社区往往较低.
- 城市森林多样性和构成对社会生态效益和气候变化脆弱性的影响未得到充分研究.
研究的目的:
- 创建明尼阿波利斯-圣保罗 (MSP) 大都会地区城市树木的特定物种的地理位置数据库.
- 分析树木多样性,组成,社会经济因素和气候脆弱性之间的关系.
主要方法:
- 综合了来自多个组织的树木库存.
- 开发了超过60万棵城市树木的地理位置数据库.
- 分析了与社会经济和人口统计数据相关的树种多样性和组成.
主要成果:
- 在MSP中的城市树木多样性是可变的,但由少数物种主导,增加了对气候变化的脆弱性.
- 由于社会经济或人口统计因素,树木多样性没有被显著预测.
- 确定了气候和社会脆弱性同时高的地区.
结论:
- 城市森林的组成,而不仅仅是树冠覆盖,对于理解社会生态效益和风险至关重要.
- 管理目标必须考虑影响城市森林多样性和弹性的社会和生态因素的复杂相互作用.

Threats to Biodiversity
22.2K
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...

What is Climate?
18.4K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
41
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...

Habitat Fragmentation
17.4K
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.
