摘要/Abstract

摘要：

人类活动和全球气候变化使得海草生态系统快速退化，形成大面积“海底荒漠”，降低了海草生态系统的生态服务功能。近年来，由于各国政府对海洋资源的逐渐重视，海草生态系统的修复进入了一个新的历史阶段。然而，目前成功修复退化海草生态系统的案例很少，急需修复生态学理论对海草修复实践进行指导。基于此，本研究系统论述了海草修复的意义、难点和问题，详细阐述了人类活动和气候变化对海草生态系统影响的交互作用及其复杂性，并整合不同研究尺度的海草修复现状和相关理论，提出针对性的海草生态系统修复对策。本研究有助于形成海草生态系统修复理论体系，为海草生态系统修复提供理论指导。

Abstract:

Human activities and climate change have caused the seagrass ecosystem to degrade and lose at an alarming rate， forming a large "submarine desert" area， leading to the loss of ecosystem service function. In recent years， because of the rising concerns on marine resources by governments， the restoration of the seagrass ecosystem has entered a new historical stage. Nevertheless， there are fewer cases of successful restoration of degraded seagrass ecosystems. Therefore， it is time to present the theories of restoration ecology to guide the practice of seagrass restoration. Under the circumstances， this study systematically discusses the significance， difficulties， and problems of seagrass restoration， elaborates the interaction and complexity of the effects of human activities and climate change on the seagrass ecosystem， integrates research methods at different scales， and proposes targeted seagrass ecosystem restoration strategies. This study contributes to constructing the seagrass ecosystem restoration theoretical system and provides academic guidance for seagrass ecosystem restoration.
