摘　　要：灌溉是获取作物高产的主要措施之一,灌溉减损经济效益与农民收入和生产经济效益密切相关。提出了从灌溉次数和灌溉量参数入手,根据灌溉投入和灌溉减损量来分析灌溉减损效益、减灾效益和生产经济效益;以华北冬麦区单点试验和调查结果为例,讨论了该方法在冬小麦减灾评估应用中的普适性和可行性。Irrigation is one of measures for achieving a higher output of crops. The economic benefit due to loss reduction by irrigation closely relates with agricultural output value and peasants'earnings. Based on the irrigation number of times and irrigation amount,the economic benefit of loss reduction from irrigation was analyzed with irrigation input and irrigation loss reduction. Taking the experimental and investigated results at some tested spots in winter wheat region of North China as examples,the feasibility of the presented method in disaster reduction assessment of winter wheat was discussed.
