Abstract: Based on the assessing method of Delphy and grain yield data of 2009 and 2011,the benefit of meteorological service for meteorological disasters of the main crops was analyzed and evaluated in Heilongjiang province.The results show that beneficial contribution rates of meteorological service for main crops in 2009 and 2011 were 4.9% and 3.1%,respectively.The occurrences times of meteorological disaster in 2009 is more than that in 2011,which leads to beneficial contribution rate of meteorological service higher in 2009 than in 2011.Compared the beneficial contribution rates of meteorological service for three crops in Heilongjiang province,the rank of beneficial contribution rate is rice >corn >soybean.For maize and soybean,contribution rate of meteorological service is the highest during the period from sowing to emergence.For rice,contribution rate of meteorological service is the highest during the period from seeding to active growing season.
