Summary
This summary is machine-generated.Understanding carbon sources and sinks is key for regional low-carbon development and achieving the "dual carbon" goal. This study analyzed spatiotemporal evolution and carbon balance in the Yangtze River Delta from 2000-2020.
Area Of Science
- Environmental Science
- Ecology
- Climate Change Research
Context
- The Yangtze River Delta (YRD) region is a critical economic hub facing significant environmental pressures.
- Understanding the dynamics of carbon sources and sinks is crucial for sustainable development and climate change mitigation.
- Policies for carbon reduction and sink enhancement require accurate spatiotemporal data.
Purpose
- To analyze the spatiotemporal evolution characteristics of carbon sources and sinks in the YRD from 2000 to 2020.
- To conduct carbon balance zoning based on carbon economy contributive and ecological support coefficients.
- To provide targeted recommendations for promoting regional low-carbon development and achieving the 'dual carbon' goals.
Summary
- Carbon emissions in the YRD increased rapidly until 2011, then fluctuated, while carbon sinks grew slowly between 2000-2020. Significant regional disparities in emissions and sinks were observed with a stable spatial pattern.
- The carbon compensation rate declined, but carbon productivity, energy efficiency, and ecological support capacity improved. Spatial patterns showed higher compensation and support in western and southern areas.
- Cities were classified into four zones (low-carbon maintenance, economic development, carbon sink development, comprehensive optimization) to guide tailored low-carbon strategies.
Impact
- Provides a scientific basis for formulating effective regional low-carbon policies.
- Identifies key areas for carbon reduction and sink enhancement initiatives.
- Contributes to achieving China's national 'dual carbon' targets (carbon peaking and carbon neutrality).
- Enhances understanding of the interplay between economic development and carbon dynamics in a major economic region.

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.
Biological Carbon Cycle

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.
Biogeochemical Cycles and Decomposition
The matter that makes up living organisms, like water, carbon, nitrogen, sulfur and phosphorous, exist in limited quantities within the...
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.
Phylogenetic trees illustrate the evolutionary relationships among these organisms. Scientists infer organisms’ common ancestry by evaluating shared morphological and genetic characteristics....
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.
In land plants, the uppermost cell layer of a plant leaf, called the epidermis, is coated with a waxy substance called the cuticle. This hydrophobic layer is composed of the polymer cutin and...
A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...
