概括

这项研究综合了生态系统服务和生态环境质量,以界定黄河流域的优先生态保护区. 建议包括扩大保护区和定制管理以加强生态保护.

科学领域:

生态保护生态保护
环境管理环境管理
遥感应用遥感应用

背景情况:

优先生态储备 (PER) 对于保护至关重要,但之前的研究往往忽视了生态环境质量 (EEQ).
黄河盆地 (YRB) 面临着需要优化保护战略的生态挑战.
整合生态系统服务 (ES) 和EEQ对于有效的PER划分至关重要.

研究的目的:

在YRB中通过结合ES和EEQ来划分PER.
确定影响PER内部ES和EEQ的关键驱动因素.
为加强YRB的生态保护提供建议.

主要方法:

利用基于遥感的生态指数 (RSEI) 来量化EEQ.
将RSEI与ESs数据结合起来,以在县级上划分PER.
采用多尺度地理加权回归来分析驱动因素.

主要成果:

在YRB中,RSEI和综合ES (CES) 显示了从2000年到2020年的波动性上升趋势.
确定了三种类型的PER:ESs储备 (上游),EEQ储备 (中/下游) 和综合储备 (中游),主要植被.
RSEI受土壤,外观,人口,PM2.5,温度和潜在的蒸发转化影响;CES受土壤,人口,PM2.5,斜率,温度,降水和潜在的蒸发转化影响.

结论:

建议为YRB扩大现有保护区至少105,379平方公里.
根据生态状况划分新区域和实施量身定制的管理策略至关重要.
该研究为YRB的环境保护和土地规划提供了宝贵的见解,支持高质量的发展和生态恢复.

What is an Ecosystem?

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:

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.

What are Biogeochemical Cycles?

What are Biogeochemical Cycles?

The most common elements in organic molecules, carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus, are only available in the ecosystem in limited amounts. Therefore, these nutrients must be recycled through both biotic and abiotic components of the ecosystem, in processes generally called biogeochemical cycles.
