“…It serves as the resource treasure, ecological barrier, economic artery, and strategic space of the GBA and thus is strategically positioned in China's overall development. Meanwhile, as the ocean is the largest carbon reservoir in the earth system [52], the conservation and restoration of marine ecosystems will help maintain its natural reproduction capacity, and help restore and expand ocean carbon sink. Long-term ecosystem-based coastal protection and management are critical to support sustainable coastal ecosystems in China in the future [53].…”

The Pearl River Estuary is in the geometric center of Guangdong-Hong Kong-Macao Greater Bay Area, which is one of the main battlefields to drive the high-quality development of China’s economy. This paper uses seven sets of typical satellite images in Pearl River Estuary for nearly half a century (from 1973 to 2021) to analyze the changes of coastline and sea reclamation. The results show that from 1973 to 2021, the total length of the coastline of the Pearl River Estuary increased from 240.09 km to 416.00 km, and that of the continental coastline from 186.87 km to 246.21 km (but the length of natural coastline in the continental coastline decreased from 136.91 km to 15.17 km). In the same period, the total reclamation area of the Pearl River Estuary increased by 28,256.06 ha. Before 2012, the growth rate of reclamation was generally fast. After 2012, the reclamation in China has entered a period of reflection. With reclamation was strictly controlled in the new era, only the previously approved reclamation projects and national major projects have been guaranteed, which makes the average annual growth rate of the coastline length and the reclamation area in the region show a significant downward trend. The reclamation in early days was largely for agriculture and pond culture purposes, but is shifting to transportation, industrial development, and urban construction in recent decades. This study scientifically analyzes the coastline and reclamation changes of the Pearl River Estuary in the past half century, which has a very important reference value for the next step to formulate marine ecological protection and restoration strategies, and construct a new pattern of marine space development and protection.

“…The distribution of CO 2 in the ocean varies greatly, and is affected by physical, chemical, and biological factors. Consequently, the quantitative estimation of the carbon absorption, transfer, and burial rates in the ocean has become an important part of marine science (Zhang, Wang, and Chen 2000;Shi et al 2014). It is estimated that the ocean offsets 30%-50% of anthropogenic CO 2 , which equals an annual mean uptake of 2 Gt C yr −1 , and the oceanic CO 2 uptake is estimated using ocean-atmosphere carbon-cycle models (Siegenthaler and Sarmiento 1993).…”

The rise in atmospheric carbon dioxide (CO 2) concentrations caused by human activities is leading to global climate change, which poses a threat to human development and survival. This study analyzed the distribution of the ocean carbon flux with interannual changes and compared it with the climatological ocean carbon flux to deepen our understanding of carbon sources and sinks. To simulate global CO 2 concentrations for the years 2008-2010, the ocean carbon flux with interannual changes and the climatological ocean carbon flux were used to drive the GEOS-Chem model, an atmospheric chemical transport model. The simulated values were compared with the CO 2 concentrations at nine observation stations to explore the influence of interannual changes in the ocean carbon fluxes on the simulated CO 2 concentrations. The authors found that the difference between the two simulation results was greater in the Southern Hemisphere all year, and the difference in autumn was the largest. Compared with the observations, the simulated CO 2 concentration of the ocean carbon flux with interannual changes is closer to the observations, indicating that this simulation is more accurate. 摘要人类活动引起大气CO 2 浓度升高导致全球气候变化，给人们生存和发展带来巨大的威胁。本研究对有年际变化的海洋碳通量与气候态的海洋碳通量的分布特征进行对比分析，加深对于碳源汇分布特征的理解。使用有年际变化的海洋碳通量与气候态的海洋碳通量分别驱动大气化学传输模型GEOS-Chem模拟2008至2010年间全球CO 2 浓度，并将模拟值与9个观测站点CO 2 浓度比较，以探究海洋碳通量的年际变化对模型模拟CO 2 浓度的影响。结果表明两种模拟结果在全年的南半球差异较大，而在四个季节中秋季的差异最大。与观测对比得到有年际变化的海洋碳通量模拟的CO 2 浓度更接近观测资料，模拟准确性更高。 ARTICLE HISTORY
