摘要
应用 DSSAT3中的 CERES-谷子模型、CROPGRO-大豆模型和 SU BSTOR-马铃薯模型分别模拟研究了黄土高原 2 8个地点谷子、大豆和马铃薯的光温生产潜力 (TPP)和气候生产潜力 (CPP) ,获得了各点 6～ 15年各作物的产量潜力值 ,并统计计算了研究时段内各作物生产潜力的平均值、标准差、最高值、最低值和水分满足率 (WCR)。
The CERES millet model,CROPGRO soybean model and SUBSTOR potato model of DSSAT3 were used to simulate the thermal productive potential (TPP) and climate productive potential (CPP) of millet,soybean and potato at 28 sites on Loess Plateau of China.The crop yield potential data were obtained at each site for 6 to 15 years.The mean yield,yield standard deviation,maximum yield and minimum yield of 3 crops,TPP and CPP were calculated on each site.And water content ratio (WCR,WCR=CPP/TPP) was also calculated.
