概括
南的建筑用地扩张显示了对生态系统服务的空间溢出效应,整体上改善了生态公平. 然而,一些地区优先考虑扩张而不是环境保护,需要平衡的发展战略.
科学领域:
- 城市规划和空间计量经济学
- 评估生态系统服务的评估
- 环境管理环境管理
背景情况:
- 城市发展和生态保护受到建筑用地扩张及其对生态系统服务的影响.
- 了解土地利用变化和生态系统服务之间的空间相互作用对于可持续的城市规划至关重要.
研究的目的:
- 从2000年到2020年,探索南建筑土地扩张和生态系统服务之间的空间相互作用.
- 在乡镇层面量化生态公平和扩张效率.
- 分析土地利用扩张对各种生态系统服务的空间溢出效应.
主要方法:
- 使用地理空间数据量化建筑用地扩张模式.
- 使用InVEST模型估计生态系统服务 (水产,碳储存,土壤保护,息地质量).
- 应用空间滞后模型 (SLM) 和空间错误模型 (SEM) 进行回归分析.
- 使用公平效率指数计算生态公平.
主要成果:
- 南的建筑用地扩张转向了"飞进"扩张,而市中心地区则出现了"填充"扩张. 整体生态系统服务增加,但在城市中心地区下降.
- 发现了显著的空间溢出效应:生态系统服务变化受到当地和邻近土地利用扩张的影响,对水产和息地质量产生更大的影响.
- 生态公平和扩张效率之间的协调得到了显著改善,尽管一些地区仍然忽视了生态保护的扩张效率.
结论:
- 城市发展战略必须采用多因素,多维的方法,将生态考虑与扩建效率相结合.
- 需要采取适应性发展政策和加强监管力度,以管理建筑用地扩张和防止生态退化.
- 平衡城市增长与生态系统服务的保护对于南的可持续发展至关重要.

Ecological Niches
24.6K
All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

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.

Design Example: Sustainability in Concrete Building
228
As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
102
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...
