基于DSSAT模型的中国水稻产量时空模拟研究
Study on Spatial and Temporal Simulation of Rice Yield in China Based on DSSAT Model
摘要
Abstract
On the basis of DSSAT model related theory,in combination with DSSAT model and GIS technology,in order to achieve the growth and yield of rice crop on the computer simulation,enhance the ability to simulate the traditional single site,solve the upscaling problem,simulate rice yield of the different periods(from 1980 to 2007)in China.The results showed that DSSAT model had good crop simulation results,the simulation results of the rice flowering,maturity,yield were desirable,and the correlation coefficient between observations and commissioning,calibration was greater than 0.56.Observational values and experimental values had a strong positive correlation,laid the foundation for the study of the spatial and temporal patterns of Chinese rice yield.关键词
