摘要
水体生态修复作为国土空间生态修复规划的核心内容逐渐成为研究热点,其中河流生境质量评价是水体生态修复规划的基础,通过科学知识图谱工具CiteSpace与VOSviewer进行文献计量分析,梳理研究脉络,研判主要领域。从研究领域看,集中于河流生物状况、水体污染物浓度、评价方法与指标、河流物理生境4个方面;从时间维度看,重要研究领域河流物理生境加速式出现是风景园林学科未来可以有所侧重的前沿方向;比较国内外研究可见,国内相关研究所采用的评价方法多参考国外评价体系。河流生境质量评价在城乡规划与风景园林学科都有较强的实践需求,但却留存较多的理论空白,应注重与相关交叉学科的研究。未来可根据研究对象的地域性特征进一步制定适合中国河流生境特征的评价指标与权重,为我国国土空间规划中河流生态修复提供一定的理论支撑与实践指导。
As the core contents in the planning of national territory ecological restoration,water ecological restoration gradually becomes a research hotspot.River habitat quality assessment is the basis of water ecological restoration planning.Based on a bibliometric analysis with the tools of CiteSpace and VOSviewer,this paper sorts out the research context and analyzes the main fields.The findings include that the major research directions are river biotic condition,water pollutant concentration,evaluation methods and indexes,and river physical habitat;from the perspective of timeline,an important research direction on river physical habitats has accelerated in recent years,which may be a frontier of landscape architecture in the future;and from the comparison of domestic and foreign studies,the domestic research adopted the evaluation methods by generally referring to foreign evaluation system.There are urgent practical requirements and theoretical blank of river habitat quality assessment in landscape architecture.In future,more attention should be paid to the cross-disciplinary research,which can focus on the locality characteristics of research objects and the evaluation indexes and weightings suitable to the river habitat characteristics in China.It provides theoretical support and practical guidelines for river ecological restoration in national territory planning system in China.
