摘　　要：为了比较不同水稻模型的适应性,利用田间观测数据,结合同期气象资料分别采用ORYZA2000和WOFOST两个模型进行了水稻生长模拟,调试确定了水稻作物生育期参数,对生育期、叶面积指数、生产量等指标的模拟结果进行了验证与适应性评价。结果表明:两个模型对于江西地区水稻生长的模拟效果较好,实测值与模拟值基本一致。ORYZA2000模型模拟的各生物量的标准化均方根误差值(NRMSE)均小于30%,而WOFOST模型模拟的叶面积指数和穗干重NRMSE值偏差较大,为41%和51%,总体模拟性能不如ORYZA2000,后者在江西省推广使用有更好的前景。The adaptability of ORYZA2000 and WOFOST of rice growth model was compared so as to realize the dynamic monitoring and scientific management of paddy field in Jiangxi Province.By the local field experimental observation data and the same period with meteorological data,the ORYZA2000 and WOFOST respectively on two model parameters for late rice crop parameters are calibrated and confirmed.The growth period,the leaf area index,and the biomass index are verified and evaluated.The results show that the two models for Jiangxi area of growth are good for the measurement values.The biomass NRMSE value is less than 30％ from ORYZA2000 model,and the NRMSE value of LAI and dry weight is 41％ and 51％ from WOFOST.The latter is better for local adaptation and simulation of experimental data.Results will provide the basis for the use and extension of rice growth model.
