中文摘要	中国西北地区幅员辽阔但水资源短缺,生态环境脆弱,节水灌溉发展迅速。合理评价节水灌溉技术的综合性能对其可持续发展十分必要。该文综合考虑西北地区生态环境脆弱性、经济发展水平、气候地理特性、灌溉发展趋势和劳动力成本等因素,提出节水灌溉技术在西北干旱半干旱地区的综合性能的评价指标体系,以生态性、经济性、适应性、精量性和智能性为准则层,共23个评价指标,通过层次分析法和模糊综合评价法确定评价指标的权重和等级阈值,并对滴灌、喷灌和小畦灌3种典型节水灌溉技术的综合性能进行了评价。结果表明:节水灌溉技术综合性能的优先序为经济性、适应性、生态性、智能性、精量性,各准则层权重最大的指标分别为亩均工程投资、水量适应性、地下水超采抑制程度、省工率和灌溉水利用系数;滴灌、喷灌和小畦灌在西北地区的综合性能评级分别为优异、一般、一般。该评价方法和结果可为当地节水灌溉技术的合理评价与选择应用提供参考。
英文摘要	Northwest China is a vast territory with scarce water resources and a fragile ecological environment system.Various water-saving irrigation techniques have been developed that need to be evaluated to facilitate sustainable development.This study presents an evaluation index system for water-saving irrigation techniques in the arid and semi-arid regions of Northwest China that incorporates the ecological vulnerability,economic development,climatic and geographical characteristics,irrigation development trends and labor costs.The model has 23 indicators in total with ecology,economics,adaptability,accuracy and intelligence level as the criterion layer.The analytic hierarchy process and the fuzzy comprehensive evaluation method were combined to determine the weights for the evaluation indicators and evaluation thresholds.The model was then used to evaluate three typical water-saving irrigation techniques,drip irrigation,sprinkler irrigation and small-scale border irrigation.The results show that the economics is the most important followed by the adaptability,ecology,intelligence level and accuracy.The most significant indicators in each of the five criterion layers are the investment per mu,water quantity adaptability,inhibition of groundwater over-exploitation,labor-saving and irrigation water use efficiency.Drip irrigation system is shown to be excellent system for Northwest China,while sprinkler irrigation and small-scale border irrigation systems have average usefulness in Northwest China.The methodology and results can be used for water-saving irrigation technique selection.
