摘要
在强人类活动干预下,流域水循环越来越呈现出"自然-人工"二元驱动结构,相应的水生态系统服务功能也呈现出明显的二元特征,这对其驱动机制和定量评价研究提出新的挑战。在深入分析流域二元水循环及水生态系统服务功能内涵的基础上,综合国内外研究现状,分析了当前研究中存在的不足;分析了自然水循环及其伴生过程和社会水循环过程对水生态系统服务功能的驱动机制,提出基于单过程单目标的四边形计算模式;基于二元水循环的多过程间多向反馈特征对水生态系统服务功能的交叉影响,构建了适用于河流、水库以及湿地等不同类型的水生态系统服务功能二元水循环评估指标体系;结合当前研究中存在的问题,提出需重点加强水生态系统服务功能评价方法以及驱动因子等方面的基础研究。
With strong impacts from human activities,hydrological cycles are exhibiting a dualistic structure（natural and artificial）.As a result,the functionality of water ecosystem service also shows dualistic characteristics,which poses a challenge to research on quantitative assessment and driving mechanism of service functionalities.Based on analysis of connotation of dualistic hydrological cycle and water ecosystem service functionalities,and present research situation of home and abroad,problems in recent studies are identified.Besides,driving mechanism of water ecosystem service functionalities caused by natural water cycle and accompanying process,as well as social water cycle process,are analyzed.And a quadrilateral computation pattern with single process and single objective was put forward.Based on multi-process and multi-feedback characteristic of dualistic water cycle cross-impact on water ecosystem service functionalities,service assessment index system under dualistic hydrological cycle mode applied to different types of water ecosystem,such as river,reservoirand wetland,was presented.Combined with existing problems of present research,it is put forward that research on assessment method and driving forces needed strengthening.
