生态保护红线保护成效评估指标体系构建

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

生态保护红线是保障和维护国家生态安全的底线和生命线,其战略地位十分重要,必须实行严格保护。在划定工作完成之后,如何科学评估生态保护红线的保护成效,对于确保其政策实施的效果,以及开展多尺度利益相关者成本效益分析等具有十分重要的意义。围绕生态保护红线“生态功能不降低、面积不减少、性质不改变、管理不弱化”的保护目标,提出生态保护红线保护成效评估的基本思路并构建评估指标体系。生态保护红线保护成效评估指标体系以生态系统状况与保护管理能力为核心,基于多元数据对比分析生态保护红线实施前后及不同阶段各项指标的评估期与基期数值,定量评估生态保护红线对于区域生态状况和生态安全的提升作用。在此基础上,可以为优化生态保护红线布局、安排区域生态保护补偿资金、实行领导干部生态环境损害责任追究制以及开展生态保护修复等提供技术支撑。

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.
