A strategy of systematic water saving agriculture was proposed based on t he analysis of t he water resource short age regime and t he agricultural water saving potential under t he background of promoting t he old industrial bases in Nort heastern China . Different p attern areas of water saving agriculture were divided ,and integrated water sav ing technique systems and water saving cultivation models were recommended ,according to t heir agricultural pro duction characteristics and develop ment requirement in t he future . The systematic strategy for sustainable utiliza tion of water resource ,t he necessity of applying proj ect for water saving and regulating rivers and watercourses synt hetically ,and t he trends in water saving research in Nort heastern China were discussed . Key words 　Water resource shortage , Systematic water saving strategy , Water saving agriculture , Sustainable utilization . 1 　引
