The Agricultural Production Systems Simulator (APSIM) was applied to simulate the 1999-2001 field experimental data and the 2002-2003 water use data at the Yucheng Experiment Station under Chinese Ecosystem Research Network, aimed to verify the applicability of the model to the wheat-summer maize continuous cropping system in North China Plain. The results showed that the average errors of the simulations of leaf area index (LAI), biomass, and soil moisture content in 1999-2000 and 2000-2001 field experiments were 27.61%, 24.59% and 7.68%, and 32.65%, 35.95% and 10.26%, respectively, and those of LAI and biomass on the soils with high and low moisture content in 2002-2003 were 26.65% and 14.52%, and 23.91% and 27.93%, respectively. The simulations of LAI and biomass accorded well with the measured values, with the coefficients of determination being > 0.85 in 1999-2000 and 2002-2003, and 0.78 in 2000-2001, indicating that APSIM had a good applicability in modeling the crop biomass and soil moisture content in the continuous cropping system, but the simulation error of LAI was a little larger.
应用农业生产系统模拟器（APSIM）对中国生态系统研究网络下属禹城试验站1999 - 2001年的田间试验数据以及2002 - 2003年的用水数据进行模拟，旨在验证该模型对华北平原小麦 - 夏玉米连作系统的适用性。结果表明，1999 - 2000年和2000 - 2001年田间试验中，叶面积指数（LAI）、生物量和土壤含水量模拟的平均误差分别为27.61%、24.59%和7.68%，以及32.65%、35.95%和10.26%；2002 - 2003年，高含水量和低含水量土壤上LAI和生物量的模拟误差分别为26.65%和14.52%，以及23.91%和27.93%。LAI和生物量的模拟值与实测值吻合较好，1999 - 2000年和2002 - 2003年的决定系数>0.85，2000 - 2001年为0.78，表明APSIM在模拟连作系统中的作物生物量和土壤含水量方面具有良好的适用性，但LAI的模拟误差稍大。
