[Objective] This study studied the change of soybean growth period and yield in future climate scenarios in Northeast China,aiming to provide scientific basis for soybean safety production,heat resources utilization and responses to effects of climate change on soybean production in Northeast China.[Method] In this study,a regional climate model and a crop model (WOFOST) were used to simulate the change of emergence,anthesis and yields of soybean during 2021-2050 in A2 (emphasizing economic development) and B2 (emphasizing sustainable development) climatic scenarios.[Result] ①Taking the B2 scenario as example,the northern planting limits of different maturity-types soybean varieties would move northward and eastward with different degrees.The appropriate area of extra-early-mature,early-mature,mid-early-mature,medium-mature,mid-late-mature and late-mature soybeans would move northward.The area of extra-early-mature,early-mature,mid-early-mature,medium-mature,mid-late-mature and late-mature soybeans would decrease,while the area of extra late-mature soybean would increase.② Under A2 scenario,the emergence and anthesis of soybeans would advance 2.2 and 3.0 days in Northeast China,respectively.Under B2 scenario,the emergence and anthesis of soybeans would advance 3.0 and 4.2 days,respectively.③ Under A2 scenario,the yield of soybeans would reduce between 2021-2030 in most area of Liaoning and Jilin with >10% decrease in eastern Liaoning and southeast Jilin.The yield would reduce by >10% in 2031-2050 in most area of Northeast China.④ Under B2 scenario,the yield of soybeans would reduce during 2021-2050 in most area,and it would reduce by >10% during 2031-2050 in most area of Northeast China.[Conclusion] Under A2 and B2 scenarios,the duration from emergence to anthesis would be shortened,the growth course would be accelerated,and the growth period might be shortened.The area with yield reduction would increase continually,and yield reduction would increase gradually.
