摘  要：
综合运用专家调查问卷、比较分析和统计学方法,系统研究了流域生态环境需水方法论与维度问题,分析了不同特征的流域如何选取和优化学科方法,从学科维度探讨了方法特征、使用范围、优选和发展趋势。结果表明,流域生态需水方法论可以从方法、学科、空间维度和程序维度4个方面进行研究。根据发展阶段和问题需求,目前学科维度重要性居于首位,重要性顺序为:学科维度(46%)>方法维度(33%)>空间维度(12%)>程序维度(8%)。学科各子维度方法数量依次为:水文学方法(31%)>生态学方法(28%)>其他方法(21%)>水力学方法(12%)>综合法(8%)。比较不同学科方法计算同流域的生态需水量结果相对标准偏差均大于0.25,差异性较大。流域生态环境需水方法在学科维度层面呈现从单学科分析向多学科综合发展、从局部过程向全流域水文循环过程发展、从传统技术向数字流域技术发展的趋势。建议以流域水环境问题为导向,以流域生态系统管理和系统优化理论为指导,以生态优先和保证基流为基本原则,对于生态参数和科学方法进行科学筛选、整合与优化。

摘  要：
Study on the environmental flows methodology is an important challenge for the watershed ecosystem management and water envi-ronmental recovery.In this paper,the issues of research methodology and dimension were conducted systematically,then the characteristics,range of application and development trends of environmental flows methodology were expounded from subject dimension,and it was dis-cussed how to adopt and optimaize methods for the different river basin based on expert questionnaire and statistical analysis.The results showed that environmental flows methodology is made up of methods,space,subject dimensions and process,of which subject is the core,and importance order was:Subjec(t46%)> Methodology(33%)> Space(12%)> Process(8%).The order of the number of sub-dimensions approach is hydrology method(31%)> ecological method(28%)> other methods(21%)> hydraulic method(12%)>holistic method(8%).After compared calculation results of water demand for the same river basin using different methods,the SD of calculated results for the same area using different methods were greater than 0.25,indicating that the variation is large.There are being three evolution trends of environ-mental flows methodology in subject dimension:changing from single discipline to multi-disciplines,changing from the local process to the whole hydrological cycle,and changing from traditional technology to digital technology.The suggestion is which method chosen for the real river basin study depends on the rule of priority for ecology and basic flows according to the key problems and ecological recovery target.The ecological parameter and methodology should be choosen,integrated and optimized.
