摘　　要：利用浅耕翻方法在内蒙古、吉林地区改良退化羊草、杂类草草场,针茅、羊草杂类草草场,冷蒿、羊草、杂类草草场面积达17.6678万亩,既改善了土壤理化性状,增加了牧草光能利用率、又改变了群落组成,提高了草场质量和牧草产量,经济效益较为显著。The use of shallow plowing to improve deteriorated grassland has been studied for 17 years in China. The types of grassland studied are Aneurolepidium chinense + forbs grassland, Stipa grandis + Ancurole pidium chinense + forbs grassland and Artemisia frigida + Aneurolepidium chinense + forbs grassland in Inner Mongolia and Jilin province. The total area which has been improved is about 11778.5 ha. The result shows that this method can improve physicochemical properties of the soil,increase the light energy utilization of grassland, change the composition of plant community, improve the quality of pastures and increase the yield of forage production. The benefits of this method is obvious.
