Abstract

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.

Key words: degradation mechanism, ecological restoration, ecological security, seagrass, community assembly
