概括
人类活动强度 (HAI) 对城市化地区的生态系统服务价值 (ESV) 有负面影响,为支持和提供服务确定了特定的门. 战略性土地管理是保持ESV平衡的关键,尽管城市化压力很大.
科学领域:
- 城市生态城市生态学
- 环境科学 环境科学
- 空间分析 空间分析
背景情况:
- 快速的城市化对城市生态可持续性和生态系统服务价值 (ESV) 构成挑战.
- 现有的研究缺乏关于人类活动如何具体影响不同的生态系统服务功能及其空间异常的清晰度.
- 了解这些机制对于有效的城市生态管理至关重要.
研究的目的:
- 调查2000-2020年间在合肥的ESV上人类活动强度 (HAI) 的驱动机制.
- 确定影响ESV各种功能组件的HAI值.
- 为了确定HAI对ESV的局部异常影响.
主要方法:
- 土地利用和土地覆盖 (LULC) 数据 (2000-2020年).
- 采用了经同等因素校正的ESV评估模型.
- 应用ESV流矩阵,HAI测量模型和GeoDetector模型进行全面分析.
主要成果:
- 合肥的ESV在2000年至2020年期间从470.12亿元人民币下降到455.34亿元人民币.
- 由于耕地转化为建筑用地,ESV损失主要是由于耕地转化为建筑用地;收益涉及建筑用地转化为耕地或水.
- HAI与ESV,监管和文化服务总体呈负相关性,支持和提供服务的过渡值为 (0.176-0.262).
结论:
- 哈伊对ESV有很大的影响,对不同类型的服务有不同的值影响.
- 确定了HAI对ESV的三个异常影响范围,突出了战略土地管理的需要.
- 这些发现为快速城市化期间的城市生态管理提供了科学基础.

Threats to Biodiversity
22.9K
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...

Habitat Fragmentation
17.9K
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.

Ecological Disturbance
17.5K
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.

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.
