By using observation data from 20 meteorological stations during 1961 - 2012 in Huaibei,Jiangsu,and simulation data with RegCM4 regional climate model under RCP4.5 and RCP8.5 emission scenarios,the variation characteristics of agricultural climatic resources like light,thermal and water conditions during soybeans growth period were analyzed with mathematical statistics. Results show that in recent 52 years,the annual accumulated temperature in the case of ≥10℃ had been average over 3 100 ℃. It remained relatively stable in the 1980s,but significantly ascended in the 1990s with obvious interannual fluctuations. Both sunshine duration and global radiation decrease evidently by - 4.9 h/a and - 7.6 MJ/m~2/ a,respectively,so tht they tended to be lower than the climatological mean values after 2000.Precipitation decrease in the 1960s;in 1970s and 1980s it was relatively stable,while in the late 1990s,it began to increase with positive water budget. Under the two future climate scenarios,light,thermal and water conditions will interannually fluctuate greatly,extreme weather events will be more frequent and active accumulated temperature will go up with a positive anomaly,so do net solar radiation and water budget. The research is beneficial to soybean production in Huaibei,Jiangsu province,based on better adaptation to climatic change and optimal selection of climate resources.
