概括
城市生态系统服务对人类福祉 (HW) 和可持续发展目标 (SDGs) 有重大影响. 虽然大多数服务有所改善,但土壤固定性下降,突出显示了复杂的城市生态动态和管理需求.
科学领域:
- 城市生态城市生态学
- 环境科学 环境科学
- 可持续性科学 可持续性科学
背景情况:
- 城市化对人类福祉 (HW) 和实现可持续发展目标 (SDGs) 提出了挑战.
- 生态系统服务 (ESs) 对HW和SDG的实现至关重要,但它们在城市环境中的影响机制是复杂的.
- 了解城市的ES对于可持续的城市管理至关重要.
研究的目的:
- 模拟主要的城市ES,并评估它们对北京HW的影响.
- 在SDG框架内揭示ESs对HW的影响机制.
- 为可持续的城市管理提供见解.
主要方法:
- 在多个尺度 (像素,城市绿地,县) 上使用生态模型模拟了五个关键的ES (NPP,WY,SC,SF,ECSI).
- 在县级上计算ES供应服务.
- 为HW建立了一个评估指数系统,以分析ES的影响.
主要成果:
- 在北京 (2000-2020年),ES显著改善 (29.14%-267.42%),但土壤固定 (SF) 减少了55.84%.
- 植物在更细微的尺度上推动了ES动态,而在县级上,城市景观模式 (例如,不透水的表面) 主导.
- 人类福利 (HW) 增加,受支持服务 (间接通过提供和监管服务) 和直接通过提供服务的影响.
结论:
- 城市ES显示了多样化的趋势,其中植被和景观模式是关键驱动因素.
- 支持ES对HW产生复杂的影响,通过提供和监管服务进行调解.
- 结果为可持续的城市规划和管理提供了有价值的参考资料.

Ecological Disturbance
17.0K
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.

Threats to Biodiversity
22.1K
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...

Levels of Organization
122.5K
Biological organization is the classification of biological structures, ranging from atoms at the bottom of the hierarchy to the Earth's biosphere. Each level of the hierarchy represents an increase in complexity that builds upon the previous level.
Molecules Are Composed of Atoms, and Biomolecules Are Assembled from Molecules:
The most basic levels include atoms, molecules, and biomolecules. Atoms, the smallest unit of ordinary matter, are composed of a nucleus and electrons. Molecules...

The Soil Ecosystem
19.6K
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

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.
