Building an Evaluation Indicator System for Assessing the Protection Effectiveness of Ecological Conservation Redline

Ecological conservation redline (ECR) is the bottom line and lifeline for safeguarding and maintaining national ecological security. It has strategic importance and should be strictly protected. Scientific evaluation of the effectiveness of ECR is important for ensuring the effect of its policy implementation and clarifying the impact of the ECR on the costs and benefits of multi-scale stakeholders. In this study, around the protection target of ECR-"Its ecological function should not be decreased, its area should not be reduced, its nature should not be changed and its management ability should not be weakened", the basic ideas and the evaluation index system of ECR protection effectiveness assessment were proposed. Focusing on the ecosystem status and management ability, and based on multi-data collected a comprehensive evaluation system was used to analyze the changes in index values before and after the implementation of an ECR. The effects of promoting an ECR to regional ecological status and security can then be recorded quantitatively. The results of assessing ECR protection effectiveness can provide technical support for optimizing its framework, and also assist in arranging ecological protection compensation funds, investigating responsibility for ecological environment damage, and carrying out ecological restoration projects within an ECR.
