摘　　要：根据作物生理、作物生态、农业气象等学科的基本原理，建立了逐时水稻冠层光合生产动态模拟模型，模型包含辐射、气温２个气象因子和密度、Ｎ肥、播种期３个栽培因子．模拟模型由５个子模型耦合而成，即发育子模型，光合生产和干物质积累子模型，固化物分配和叶面积动态子模型，产量形成子模型和辐射、气温模拟子模型．利用模型对水稻生长的动态过程进行仿真，将模拟值和实测值进行比较。Based on the principles of phytophysiology, phytoecology and agrometeorology, a dynamic computer simulation model was developed for simulating photosynthetic production of rice canopies with per hour changing course, which contains climatic factors i.e., radiation, temperature, day length and 3 cultivative ones, i.e., planting density, the amount of fertilizer N and sowing dates. The model consists of 5 submodels, i.e., that of photosynthesis and respiration, the biomass accumulation and yield formation, the dynamics of leaf area, the dynamics of field ecological factors, rice development. By using the model, the process of rice gowth was simulated and the results were very desirable in comparision with the observations, showing the rationality of simulating model.
