科学领域:

环境科学环境科学
生物地质化学生物地质化学
临界技术临界技术

背景情况:

湖泊缩通常是通过生态水分转移来管理的.
人类引起的水文变化对湖泊碳循环的影响仍然不太清楚.

研究的目的:

调查河流向湖水转移对泰湖环氧化湖碳循环的影响.
量化气体和溶解碳流与水分流相关的变化.

主要方法:

从2011年到2017年,对二氧化碳和CH4流量,二氧化碳等价排放量以及溶解有机碳 (DOC) 和溶解无机碳 (DIC) 进行了整合性现场测量.
在太湖的接水区和参考区之间进行了比较.

主要成果:

水的转移显著增加了接收水区的总气体碳排放量 (二氧化碳当量).
甲 (CH4) 排放量在接水区与参考区相比翻了一番.
水的转移导致了DOC的减少,但增加了DIC,特别是在流入河口附近.

结论:

人工水分流可以增强气体碳的产量,可能通过刺激DOC矿化和营养丰富.

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 an Ecosystem?

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

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.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

The Water Cycle

The Water Cycle

The Earth’s hydrosphere includes all of the areas where the storage and movement of water occurs. Since water is the basis of all living processes, the cycling of water is extremely important to ecosystem dynamics.
