Introduction

Introduction

GB/T 42642—2023 Technical Guidelines for Ecological Restoration Monitoring and Effect Evaluation of Marine Benthic Animal Populations is an important standard in China for the field of marine ecological protection and restoration, aiming to standardize the ecological restoration monitoring and effect evaluation of marine benthic animal populations.

Comparison of Standard Frameworks

Dimensions	Standard Requirements	Implementation Points
Working Procedures	Includes preparation stage, monitoring and investigation stage, effect evaluation stage and report preparation stage.	Ensure that the time arrangement of each stage is reasonable and the data records are complete.
Monitoring indicators	Three major indicators: biological environment, sedimentary environment, and economic benefits.	Select core monitoring indicators based on actual restoration goals.
Evaluation methods	Include survival rate assessment, sedimentary environment restoration effect assessment, and large benthic biodiversity index assessment.	Adopt a comprehensive assessment system that combines quantitative and qualitative methods.

Implementation suggestions

Preparation:Before implementing ecological restoration, a background survey should be carried out to ensure that the initial state of the damaged area is mastered. At the same time, a detailed monitoring and effect evaluation work plan should be formulated to clarify the goals, methods, and time arrangements.

Monitoring methods:During on-site monitoring surveys, stations should be set up in strict accordance with standard requirements, and samples should be collected regularly. During the data processing stage, statistical methods should be used to analyze the restoration effect.

Economic evaluation:Economic benefit evaluation is an important part of ecological restoration. By calculating the input-output ratio, a scientific basis can be provided for decision-making on subsequent restoration projects.
