まとめ
河北省生态系统服务功能下降,栖息地质量和碳储量减少。确定了中部和南部地区为生态改善优先区域,为保护工作提供了基础。
科学分野:
- 生态经济学和环境科学,侧重于生态系统服务评估和管理。
背景:
- 理解生态系统时空动态对于可持续发展和生态资产管理至关重要。; 河北省在经济增长与环境保护之间取得平衡方面面临挑战,因此有必要对其生态系统服务进行评估。
研究 の 目的:
- 研究河北省1990年至2020年关键生态系统服务(碳储量、栖息地质量、水量保持、土壤保持)的演变模式。; 评估这些服务之间的权衡与协同作用,并确定优化的优先区域。; 为该地区的生态环境保护和生态资产管理提供理论基础。
主な方法:
- 利用InVEST模型评估了四项生态系统服务:碳储量、栖息地质量、水量保持和土壤保持。; 采用空间自相关和生态系统服务权衡协同程度(ESTD)模型分析权衡与协同作用。; 应用贝叶斯网络设计优化情景并确定生态系统服务改善的优先区域。
主要な成果:
- 碳储量和栖息地质量呈下降趋势,而土壤保持量先降后升。; 高生态系统服务分布集中在河北省东北部,中部和南部地区水平较低。; 协同关系主导了生态系统服务的相互作用,但存在显著差异和特定服务之间协同作用低迷的时期。
結論:
- 降水、潜在蒸散量、高程和土地利用类型被确定为影响生态系统服务的关键变量。; 确定了主要的优先优化区域,主要位于河北省中部和南部,占全省总面积的5.93%。; 该研究为河北省生态管理中的生态功能区划和靶向改进提供了科学依据。

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
269
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...

Ecological Niches

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.

Region of Convergence
861
The z-transform is a powerful mathematical tool used in the analysis of discrete-time signals and systems. It is a crucial tool in the analysis of discrete-time systems, but its convergence is limited to specific values of the complex variable z. This range of values, known as the Region of Convergence (ROC), is fundamental in determining the behavior and stability of a system or signal. The ROC defines the region in the complex plane where the z-transform converges, which can take various...
