概括

中国黄河流域的生态系统服务正在发生变化. 水产和土壤保护增加,而息地质量下降,受环境和社会经济因素的影响.

科学领域:

环境科学环境科学
生态生态学生态生态学
地理地理地理地理.

背景情况:

黄河流域 (YRB) 具有生态意义,但面临生态系统服务 (ES) 转型.
了解ES动态和驱动因素对于YRB中有效的环境政策至关重要.

研究的目的:

评估从1980年到2020年在YRB中ES的时空动态.
确定ES转型的模式和影响这些变化的因素.

主要方法:

利用InVEST模型评估水产,土壤保护和息地质量的时空动态.
使用基于参数的最佳地理探测器 (OPGD) 来分析影响ES转换的因素.
确定了分析的最佳空间尺度是一个45公里的网格.

主要成果:

整个YRB的水产量增加,南部和东部的价值更高.
土壤保护也增加,在南部和西部地区显示较高的值.
随着时间的推移,息地质量下降,从东南向西北的空间下降.
确定了三个转变模式:同时增加 (水产,土壤保护),增加-减少 (土壤保护,息地质量) 和增加-恶化 (水产,息地质量).
自然,地理,社会经济和政策因素在2000年至2020年间影响了ES转型.
影响ES转型的关键相互作用包括经济密度和降水,温度和生态恢复,收入和植被指数.

结论:

年轻人生态区在生态系统服务方面经历了重大转变,水产,土壤保护和息地质量趋势各不相同.
自然和人为因素的复杂相互作用推动了ES的转型,突出显示了对综合管理战略的需求.
这些发现为制定有针对性的环境政策提供了关键的见解,以确保黄河流域的可持续发展.

The Soil Ecosystem

The Soil Ecosystem

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:

Threats to Biodiversity

Threats to Biodiversity

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 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.

Bioremediation

Bioremediation

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.

Ecological Succession

Ecological Succession

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...
