| 英文摘要 | As a water layer with significantly reduced dissolved oxygen (DO) in the ocean, the oxygen minimum zone (OMZ) plays a crucial role in regulating marine organism distribution, global material cycles, and climate change. Based on a systematic review of recent studies on OMZ, this paper summarizes the DO thresholds, structural characteristics, distribution patterns, formation and maintenance mechanisms, and driving factors of OMZ in the ocean in the context of global change. The DO thresholds of OMZ typically range from 20 to 100 mu mol L-1. Specifically, the threshold is mostly 20 mu mol L-1 in regions with intense OMZ, such as the Eastern Pacific and Northern Indian Oceans, while it is mostly 100 mu mol L-1 in regions with mild OMZ, including the Western Pacific and Atlantic. In terms of structure, the OMZ is mainly composed of three parts: the upper oxycline, the lower oxycline, and the OMZ core. Significant differences exist in the horizontal and vertical distributions of OMZ across different regions. OMZ is mainly concentrated in tropical and subtropical regions, with the widest distribution in the eastern tropical North Pacific. The upper boundary of OMZ is shallower (50-150 m) in significantly affected regions, whereas it is below 200 m in less affected regions. The formation of OMZ is governed by the continuous consumption of DO in the ocean interior, and the water exchange restriction caused by seawater stratification, whereas the maintenance of the hypoxic state of OMZ relies on two positive feedbacks: increased microbial oxygen consumption due to reduced animal feeding, and increased oxygen consumption by anaerobic metabolic products. In the context of global change, rising temperature is the main driver of OMZ expansion, reducing O2 solubility, increasing respiration and decomposition rates, and enhancing seawater stratification. Additionally, the structure and evolution of OMZ is also profoundly affected by ocean circulation such as thermohaline circulation, wind-driven circulation, and upwelling, as well as changes in wind stress, mesoscale eddies and freshwater flux. Future research should focus on establishing OMZ gradient thresholds and classification criteria based on the law of deoxygenation, improving the systematic understanding of the temporal and spatial variations of OMZ, and continuously strengthening studies on OMZ in the Western Pacific. |
