Abstract:

Ecological effect evaluation is a critical component in ecological and environmental damage assessment, providing an essential foundation for ecological damage compensation and restoration efforts. We systematically analyze ecological effect evaluation indictors, assessment methodologies, and damage identification pathways through a comprehensive literature review. Case studies validate the effectiveness of the established model in scientifically assessing the impact of pollutants on ecosystem service value, offering both methodological references and practical insights for similar research in other regions, with significant theoretical and applied implications. To address existing challenges, we propose improvements in optimizing ecological evaluation methodologies, refining technical frameworks, establishing cross-sectoral coordination mechanisms, and developing professional expertise. The principles and strategies proposed in this paper aim to enhance the scientific rigor and accuracy of ecological assessments, advance the standardization of ecological and environmental damage assessment systems, and provide valuable references for future research in related fields.

Key words: ecological and environmental damage assessment, ecological effect evaluation, ecological assessment indicators and methods, damage quantification
