河流生态修复后评估研究进展

Advances in post evaluation of river ecological restorations

河流生态修复活动正在世界范围内广泛开展,受生态系统内部结构的复杂性、非线性等因素制约,生态修复工程实施后的效果仍有待进一步确定。通过分析国内外河流生态修复后评估研究进展情况,总结了河流生态修复成功与否的判别标准及国内外开展的相关实践活动,指出国外的河流生态修复后评估工作主要集中在欧美国家,内容相对较详细;我国的河流生态修复后评估工作受河流生态修复研究和实践水平所限,仍处于初级阶段,应积极借鉴国外后评估工作的经验,推进我国河流生态修复工作的进一步深入。

Although river ecological restorations have been widely implemented around the world,the effects of ecological restoration projects still need to be further identified due to the complexity and nonlinearity within the internal structures of ecosystems.Based on the analysis of the domestic and overseas advances in post evaluations of river ecological restorations,the criteria for ecologically successful restorations and the related practices at home and abroad are given.Since the post evaluations of river ecological restorations are regularly carried out in the Europe and the United States,the contents are more detailed.Due to the limitation on the investigations and practices of the river ecological restorations,the post evaluation is still at the primary stage in China.Therefore,it is necessary to learn from the overseas experiences on post evaluations and further promote the implementation of river ecological restoration in China.
