摘　　要：为了解敦化市的耕地质量状况,2006—2009年对敦化市土壤进行采集,进行理化分析。结果表明,敦化市现有耕地9.81万hm2,划分为8个等级。高产田(1级地和2级地)占25.68%,中产田(3级地、4级地和5级地)占68.72%,低产田(6级地、7级地和8级地)占6.1%。与第2次土壤普查时相比,敦化市高产田和中产田所占比例增加,低产田所占比例有所下降。In order to investigate the quality status of farmland of Dunhua City,soil samples were selected in Dunhua City from 2006 to 2009 and measured physical and chemical properties.The results showed that there were 9.81 million hm 2 cultivated land in Dunhua City now,divided into eight grades.High-yield field （the first grade field and the second grade field） accounted for 25.68%,medium-yield field （the third field,the fourth and the fifth field） accounted for 68.72%,and low-yield field （the sixth field,the seventh field and the eighth field） accounted for 6.1%.Comparing with the soil from the second soil survey,the proportion of high-yield field and medium-low yield field increased,and low-yield field decreased.
