Abstract

The ecological conservation redline (ECR) strategy is a new model for China’s ecological environmental protection that has attracted increasing attention. Ecological compensation is an effective means to promote ECR management. Although China’s ECR policy has been fully implemented, the ecological compensation mechanism remains underdeveloped, and there is an urgent need to establish a compensation standard accounting framework that meets the requirements of ECR management. This study proposed an ecological compensation accounting framework based on the protection requirements of “no reduction in function, no transformation in nature, and no reduction in area” and took Jiangsu Province, China, as a case study to estimate the ECR compensation standard. The results indicate that ECR policy effectively promotes the protection and restoration of important key ecosystems in this important ecological region. Influenced by factors such as ecosystem service value (ESV) variation, ECR distribution, and socioeconomic considerations, ecological compensation standards differed among cities during the same period. In the long term, ecological compensation standards increased with the ESV net gain and displayed a gradually increasing trend under ECR policy. Currently, the ecological compensation model is mainly organized by the government, and the sources of ecological compensation funds are limited. Government fiscal funds are limit to meet the great need of compensation, and there are serious deficiencies in inter-regional compensation especially for market oriented compensation approach between regions. It is difficult to meet the needs of ecological compensation using existing compensation methods, and diversified compensation methods such as tax exemption compensation, resident resettlement compensation, project construction compensation, resource sharing compensation, and market-oriented compensation should be adopted to improve the ecological compensation mechanism.
基于目标需求的生态保护红线战略生态补偿量化研究——以江苏省为例
生态保护红线(ECR)战略是中国生态环境保护的新模式,受到越来越多的关注。生态补偿是推进ECR管理的有效手段。虽然中国的ECR政策已经全面实施,但生态补偿机制仍不完善,迫切需要建立符合ECR管理要求的补偿标准核算框架。本研究提出了基于“功能不减少、自然不改变、面积不减少”保护要求的生态补偿核算框架,并以江苏省为例估算生态补偿标准。结果表明,ECR政策有效地促进了该重要生态区重要关键生态系统的保护与恢复。受生态系统服务价值(ESV)变化、ECR分布和社会经济因素的影响,同一时期城市间生态补偿标准存在差异。长期来看,生态补偿标准随ESV净收益的增加而增加,并在ECR政策下呈现逐渐增加的趋势。目前,生态补偿模式主要由政府组织,生态补偿资金来源有限。政府财政资金难以满足巨大的补偿需求,区域间补偿特别是以市场为导向的区域间补偿方式存在严重不足。现有的补偿方式难以满足生态补偿的需求,应采取免税补偿、居民安置补偿、项目建设补偿、资源共享补偿、市场化补偿等多元化补偿方式,完善生态补偿机制。

期刊介绍: The Journal for Nature Conservation addresses concepts, methods and techniques for nature conservation. This international and interdisciplinary journal encourages collaboration between scientists and practitioners, including the integration of biodiversity issues with social and economic concepts. Therefore, conceptual, technical and methodological papers, as well as reviews, research papers, and short communications are welcomed from a wide range of disciplines, including theoretical ecology, landscape ecology, restoration ecology, ecological modelling, and others, provided that there is a clear connection and immediate relevance to nature conservation. Manuscripts without any immediate conservation context, such as inventories, distribution modelling, genetic studies, animal behaviour, plant physiology, will not be considered for this journal; though such data may be useful for conservationists and managers in the future, this is outside of the current scope of the journal.
