摘要
作为农业决策支持系统,DSSAT模型被许多国家广泛应用.但是,该模型的良好应用是建立在大量数据支持的前提之下的.为此,本文介绍了DSSAT4.0模型的功能结构和特点,详细说明了洛阳孟津地区模型气象、土壤和作物品种参数等各指标参数数据库的建立过程,为DSSAT4.0模型在洛阳孟津县地区农业生产应用研究提供数据支持.
As the decision support system for agrotechnology, DSSAT has been applied worldwidely in some country. But, a large numbers of data must be collected for application of DSSAT model exactly. So, the structure and function of DSSAT 4.0 model were introduced. The databases of weather, soil and crop growth parameter of DSSAT 4.0 model in Mengjin in Luoyang were created, and creating process of every object in databases were explained particularly. It is well data support for optimizing and chossing cropping model of Water conservation in Mengjin in Luoyangcity.
