摘要： The DSRODCBSM is one of important members of Chinese crop model series. It was developed in the researches based on field experiments from 2002 to 2005 in middle valley of Yangtze river in china, combining relative data from literature of rape researches with it, employed ideas of R/WCSODS, through developing simulation models of rape growth and development (including phenology, biomass, LAI, and shoot number dynamic models, etc.),* dynamic models of soil water and nitrogen during rape growth season,and the optimization models for rape cultivation (including the optimum season, LAI, shoot numbers, sowing rate, fertilization rate, and soil moisture, etc. ), in accordance with principles of agricultural system sciences, and incorporated simulation with optimization principles for rape cultivation and expert knowledge. The excellences of the system were as follows, (1) gained optimization decision-making cases in normal year before planting, dynamic cases for modification and controlling in differentstages in current year by predicting under the different conditions of climates, soil, varieties, yielding levels, plant patterns, etc., (2)printed pattern tables very soon according to the decision -making cases the above, and provided decision makingsupport for agricultural manager, technician, and farmer directly, and (3 Characteristics with aim, optimization, dynamic, and digital in decision-making.
