森林与径流关系研究进展

Research Advances in Forest-Runoff Relationship

森林与径流的关系一直是林学、生态学以及水文学领域研究的难点和热点问题,至今依然存在较大争议。全世界开展了一个多世纪的集水区观测试验,也呈现出截然不同的观测结果。本文系统梳理世界上不同地区广泛开展的基于单独/配对集水区试验的森林与径流关系的研究结果,探讨森林与径流关系的争论观点和争议来源,指出未来应加强的研究方面:1)开展大尺度、多尺度耦合与精细化研究;2)开展跨站点、跨区域整合研究;3)注重过程、机理及模型模拟研究;4)加强多学科交叉、多方法比较的系统性研究。

The effects of forest cover change on water yield, a hotspot as well as a difficult issue in the fields of forestry, ecology and hydrology, still exist great debate. Observations of numerous watershed experiments that have been conducted for a century throughout the world also vary greatly and remain controversial. Here, based on the observations of globally published paired-watershed experimental and the time-trend result , we comprehensively presented the divergent opinions on the effects of forest cover change on water yield and analyzed the potential underlying mechanism. After that, we further summarized four aspects which need to be emphasized in future studies: 1) to develop carbon and water coupling research at multiple scales;2) to develop multiple sites and cross-regional integration research;3) to concentrate on hydrological and ecological processes, mechanism and modeling;4) to strengthen the cross-penetration and integration of different disciplines and technical fields studies.
