摘　　要：节水农业综合效益评估是节水农业中最基础的工作,在分析国内外节水农业综合效益评估研究的基础上,首次提出了南方季节性缺水灌区节水农业综合效益评估指标体系。节水农业工程系国民经济基础设施,其综合效益评估涉及面广、因素庞杂。鉴于此,在灌区节水农业纵、横比较分析的基础上,采用LFA理论,经逻辑分层、归类,构筑出4层次、3大类、24项单因子指标的区域性节水农业综合效益评估指标体系。Evaluation of the comprehensive benefits of the water-saving agriculture is the most basic work in the water--saving agriculture. On the basis of the analyses of the development of the research on the evaluation of the comprehensive benefits of the watersaving agrieuhure domestic and abroad, this article proposes for the first time the evaluation index system for the comprehensive benefits of water-saving agriculture in the seasonal water deficit irrigation district in the southern China. Water saving agriculture engineering is the infrastructure of national economy, so evaluation of the comprehensive benefits involves a wide range of knowledge, numerous and jumbled factors, In view of this, this article adopts LFA theory to set up the index system on the basis of historical, inter-comparison analysis of water-saving agriculture of irrigated district through logical lamination, and classification. The system comprises of 24 single factors, 3 classes at 4 levels. ：
