概括
农业环境计划改善了息地质量,但在碳储存和生态系统连接方面取得的收益很小. 有针对性的措施增强了连接,揭示了不同景观中的生态系统服务 (ES) 之间的权衡.
科学领域:
- 环境科学,农业生态学,景观生态学,保护科学.
背景情况:
- 农业环境和森林计划旨在保护生态系统,但由于实施-交付差距,它们的有效性受到争议.
- 了解这些计划对多种生态系统服务 (ES) 的影响对于优化保护策略至关重要.
研究的目的:
- 模拟和比较不同农业环境和森林措施对不同 ES 的影响.
- 评估加强和以连接为重点的措施对息地质量,碳储存,生产收入和生态系统连接的影响.
- 在高自然价值景观的不同实施场景下,确定ES之间的协同效应和权衡.
主要方法:
- 利用高分辨率的地理空间场景 (基线,增强,增强+连接) 来建模农田和森林措施的影响.
- 模拟了一系列生态系统服务,包括息地质量,碳储存,生产收入和生态系统连接.
- 采用多变量分析来识别措施捆绑及其相关的ES影响,根据景观特征进行背景化.
主要成果:
- 增强情景显示,息地质量有很强的增长 (28%),但碳储存 (2%) 的增长较弱,生产收入 (-7%) 和连接 (-2%) 的损失较小.
- 增强+连接场景显示生态系统连接的显著改善 (15%),其他ES的类似趋势.
- 确定了八个不同的措施包及其对ES的不同影响,突出了景观特定的响应.
结论:
- 农田和森林措施的综合应用可以显著改善息地质量和连接性.
- 不同的生态系统服务之间存在权衡,需要仔细规划和定位保护措施.
- 这项研究为各种景观中联合农业环境和森林干预措施的潜在协同效应和权衡提供了新的见解.

The Soil Ecosystem
19.7K
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:

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.

Key Elements for Plant Nutrition
18.7K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Sustainable Development
13.2K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.
