摘要: 本文根据传统田间灌水质量指标体系存在的不足首次提出了有效田间灌水质量指标体系的概念。作者认为,传统的田间灌水质量指标体系只从灌水结束后通过土壤表面的累计入渗水深来描述灌水质量,缺乏合理的理论根据,不利于直接反映灌水质量与作物生长之间的关系。建议从作物根系吸水机理上研究灌溉入渗水分及其分布状况的有效性,建立有效的田间灌水质量指标体系。文中对有效田间灌水质量指标体系的概念进行了较系统的阐述,最后还初步探讨了田间灌水质量指标体系中的随机性和时空性问题。

Abstract: This paper first sets up the concept of the effective irrigation quality index system of field water application. The authors hold that the traditional irrigation quality index system of field water application lacks reasonable theoretical grounds and is inadequate to reflect the relationship between irrigation quality and crop production because it only describes irrigation quality by the depth of water infiltrated through soil surface. It is suggested to study the useful water volume of the total applied water and the effective distribution of this part of water, and then to establish an effective irrigation quality index system of field water application. The con-.cept of the effective irrigation quality index system of field water application and the current achievements in this field are discussed systematically in this paper. At last, the stochastic and timespace problems in irrigation quality index system of field water application are also analysed.

Key words: field water application, effective irrigation quality index system, efficiency index, uniformity index
