概括

连续覆盖林业 (CCF) 提供了一种更具成本效益的森林管理方法,与传统旋转林业 (RF) 相比,增强生物多样性和生态系统服务. 多功能景观需要不同的策略.

科学领域:

林业科学林业科学
生态生态学生态生态学
环境经济学环境经济学

背景情况:

芬诺斯坎迪亚的北极森林面临着经济木材生产与生物多样性保护和气候减缓等环境目标之间的权衡.
为了木材而进行的密集的历史森林管理导致了环境变化和与保护政策的冲突.
目前的管理实践,特别是增加收获,威胁着生物多样性和碳库存.

研究的目的:

在北极森林中量化和比较旋转林业 (RF) 和连续覆盖林业 (CCF) 的成本效益.
评估这些制度对经济产出,生物多样性保护和碳库存的影响.
探索森林属性 (土壤类型,地点类型,立年龄) 如何影响管理制度的表现.

主要方法:

在芬兰北部的北极森林中,模拟了45559个100多年的森林.
开发了两个成本效益指数 (CEI) 来评估经济产出,生物多样性 (六种脊椎动物物种) 和碳库存.
分析了土壤类型,地点类型和位年龄对管理制度结果的影响.

主要成果:

连续覆盖林业 (CCF) 一般显示生态系统服务和生物多样性保护的成本效益高于旋转林业 (RF).
无论是RF还是CCF的表现都取决于最初的摊位特征,受先前管理的影响.
CCF不是普遍最佳的,需要针对特定立场条件采取替代策略.

Production Efficiency

Production Efficiency

Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

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 Disturbance

Ecological Disturbance

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.

Variability: Analysis

Variability: Analysis

Measures of variability are statistical metrics that reveal the dispersion pattern within a dataset. They are pivotal in biostatistics, providing insights into the heterogeneity within health and biological data. Variability signifies the degree to which data points diverge from one another, helping researchers understand the potential range of values and associated uncertainty within the data.
The range is a simple measure of variability, indicating the difference between the highest and...

Ecological Niches

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.
