概括

生态质量和生态系统健康显示,公河流域的空间一致性很高,尽管在特定的土地用途和高海拔地区出现了差异. 分析在低海拔,人类影响较小的环境中最有效.

科学领域:

环境科学环境科学
遥感遥感遥感遥感
生态生态学生态生态学

背景情况:

生态质量 (EQ) 和生态系统健康 (EH) 是关键的环境指标.
之前的研究还没有充分探索EQ和EH之间的空间关系.
了解空间的一致性对于有效的环境管理至关重要.

研究的目的:

调查公河流域生态质量和生态系统健康之间的空间一致性.
确定EQ和EH指标之间的分歧和趋同领域.
评估土地使用和海拔高度对EQ和EH之间的关系的影响.

主要方法:

应用遥感生态指数 (RSEI) 来评估生态质量.
利用活力,组织,弹性和服务 (VORS) 模型来评估生态系统的健康.
在公河流域进行了RSEI和VORS输出之间的空间比较分析.

主要成果:

在生态质量 (RSEI平均值=0.56) 和生态系统健康 (EHI平均值=0.59) 之间发现了很高的整体空间一致性.
在草原和耕地中观察到差异,可能是由于VORS模型的生态系统服务优先级.
显著的空间不对称性和较低的相关性在高海拔荒的土地地区被发现.

结论:

生态质量和生态系统健康表现出强大的空间一致性,特别是在低海拔地区,人类影响较小的地区.
对EQ和EH的空间分析在自然环境中最可靠,人类干预最小.
高度和土地使用类型可以影响观测到的EQ和EH之间的空间关系.

Dimensions of Health and Illness

Dimensions of Health and Illness

The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.

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:

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.

What is Biodiversity?

What is Biodiversity?

Biodiversity describes the variety of living things at multiple organizational levels: genetic, species and ecosystem diversity. Species diversity includes all branches of the evolutionary tree from single-celled prokaryotic organisms, bacteria, and archaea, to the eukaryotic kingdoms: plants; animals; fungi; and protists. To date, there have been about 1.75 million species identified, and new species are discovered every week.

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.
