海洋酸化对海洋生态系统的影响 -环境工程专业

摘要

随着全球化的深入发展，海洋酸化问题变得越来越严重，对生态和渔业资源构成威胁。本文深入分析了海洋酸化的概念、原因、科学基础及其对生态系统服务的广泛影响，并提出了相应的解决措施。文章首先概述了海洋酸化作为全球气候变化的一个关键方面，其主要原因是人类活动导致的二氧化碳浓度上升。接着，文章探讨了海洋pH值平衡、二氧化碳与海洋酸碱度的关系，以及人类活动如何加速这一过程。重点分析了海洋酸化对生态系统服务的三个主要影响：削弱海洋碳汇功能、威胁渔业资源和损害生物多样性。针对这些问题，本文提出了一系列策略，包括减少CO2排放、促进海洋生物适应、建立监测网络、发展新技术和推动全球治理框架，旨在缓解海洋酸化，保护海洋生态。最后，文章总结了研究的主要发现，并指出了未来研究的不足和方向，强调了全球合作在应对海洋酸化挑战中的关键作用。

Abstract

With the deepening of globalization, the problem of ocean acidification is becoming more and more serious, posing a threat to the ecology and fishery resources. In this paper, the concept, causes, scientific basis of ocean acidification and its extensive impact on ecosystem services are analyzed, and corresponding solutions are proposed. The paper begins by outlining ocean acidification as a key aspect of global climate change, the main cause of which is rising carbon dioxide concentrations due to human activities. The paper then explores the ocean pH balance, the relationship between carbon dioxide and ocean pH, and how human activities can accelerate this process. Three main impacts of ocean acidification on ecosystem services were analyzed: weakening the Marine carbon sink function, threatening fishery resources, and damaging biodiversity. In response to these issues, the paper proposes a series of strategies, including reducing CO2 emissions, promoting Marine adaptation, establishing monitoring networks, developing new technologies, and promoting a global governance fr amework aimed at mitigating ocean acidification and protecting Marine ecology. Finally, the paper summarizes the main findings of the study and points out shortcomings and directions for future research, highlighting the key role of global collaboration in addressing the challenges of ocean acidification.
