概括
印度库什喜马拉雅山脉的当地人优先考虑水产和作物生产,除了作物生产外,大多数生态系统服务 (ES) 的感知增加. 社区特点,而不是社会经济因素,驱动ES偏好和变化.
科学领域:
- 生态系统服务研究研究
- 景观规划和管理 景观规划和管理
- 人类主导的景观.
背景情况:
- 生态系统服务 (ES) 的需求方面,包括当地偏好和对其供应和相互作用的看法,对于有效的景观管理至关重要,但仍未得到充分探索.
- 了解这些社会维度在人类主导的景观中尤为重要,因为人类活动在很大程度上影响了生态系统功能.
研究的目的:
- 调查印度库什喜马拉雅地区6个主要生态系统服务 (ES) 的当地人民的偏好,感知变化和相互关系.
- 分析社区的空间异质性如何影响ES的需求和感知.
主要方法:
- 使用半结构化问卷进行了社会调查,对300个家庭进行了10个定居点类别的社会调查,分层按流域和土地覆盖进行了分层.
- 使用加雷特平均得分 (GMS),顺序逻辑回归和奇平方测试来分析定量数据.
- 使用诱导方法分析了定性数据.
主要成果:
- 水产 (GMS=70) 和作物生产 (GMS=66) 是最喜欢的ES,而息地质量 (GMS=37) 和碳封存 (GMS=35) 是最不喜欢的.
- 超过70%的受访者指出,在过去二十年中,农作物产品供应有所下降,而大多数其他ES被认为正在增加.
- 当地人认为大多数ES对之间存在协同作用的关系,直接的权衡占据了被认为的ES相互作用的主导地位.
结论:
- 在社会经济方面,ES偏好和感知到的变化更多地受到社区的空间异质性 (流域,市政,土地覆盖类型) 的影响,而不是社会经济因素.
- 为优化ES供应和管理,建议进行基于地点的空间评估,农业林业,激励非本地ES,以及综合的生物物理社会经济评估.

Threats to Biodiversity
22.4K
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...

Ecological Succession
17.3K
Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...

Keystone Species
21.7K
Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a...

Factors Affecting Perception
1.6K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

Ecological Disturbance
17.2K
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.
