基于多属性分析的农田排水标准

Standard of farmland drainage based on multi-attribute analysis

农田排水标准是确定农田排水工程规模、布局的重要依据之一。近年来,农田排水的环境、生态、社会效应日益凸显,由此带来的诸多问题逐渐受到重视。在制定农田排水标准时,如何充分考虑农田排水的多种效应,进而客观评价排水工程效益,合理确定排水工程规模和布局,是新时期农田排水标准研究中急需解决的问题。从经济、环境、生态及社会等方面总结了农田排水标准的研究现状,对农田排水标准的经济、环境、生态及社会属性进行分析,指出单纯依靠经济评价确定排水标准的不足,提出研究、建立农田排水综合控制标准的必要性和发展方向以及对此需要进一步研究的问题。

A farmland drainage criterion is one of the most important references for determination of scale and layout of farmland drainage construction. Recently, the environmental, ecological and social effects of farmland drainage appear more apparently and get more and more attention. Therefore, how to take its multi-effects into full consideration, to evaluate the benefits of farmland drainage construction objectively and to determine the appropriate scale and layout of drainage project are the main issues urgent to be solved for the farmland drainage criteria research. The research status of farmland drainage criteria was generalized from the perspective of economy, environment, ecology and society. And its multi-attributes in these terms were discussed in greater details here. In addition, the determination of drainage criteria just considering its economic benefits but ignoring its environmental, ecological and societal effects is pointed out as its main disadvantage. Aiming that, the necessity of research on the integrated control criteria of farmland drainage was raised. Besides, its development trend and some questions needed deeper research were also illustrated.
