双季稻田生态系统信息管理的调控决策支持系统(DOREIDS)研究

A Decision-making Support System for the Information Management of the Double-cropping Rice Ecosystem (DRESS)

阐述了DORIEDS的设计思想、整体设计、基本功能及展望。该系统是由综合调控系统 (ICS)与专业调控系统 (PCS)组成的双层结构。ICS是 4个PCS的总平台 :技术信息系统 (作物技术措施知识库 )、环境信息系统 (环境信息数据库 )、技术经济评价系统 (2 0余种作物种植方式的数据库和模型库 )以及RICAM 1.3(水稻生长发育预测模型 )。DORIEDS的基本功能为 :信息查询和情景分析 ;生长发育和产量形成进程的预测 ;优化农艺方案和应变决策的建议 ;新品种适应性的预估和杂交水稻制种的花期预测 ;水稻育种的理想株型的模拟 ;

This paper describes the design, the structure and the basic functions of DRESS, the Double-cropping Rice Ecosystem-management Support System. It is a two-layer structure system that consists of four professional control system (PCS) and an integral control system (ICS). The ICS is the general platform of the four PCS: technical information system, environmental information system, economical evaluated information system and a rice growth simulation model. The first three PCS represent the knowledge-base of crop management actions, the data-base of environment variables, and the empirical economic model base of various rice-based multiple-cropping system, respectively. The last PCS, the rice simulation model, is the Rice Calendar Model (RICAM 1.3). The basic functions of DRESS are: information mining, simulation, analysis, forecast of rice yield-related processes, determination of the optimum environment-dependent management actions, assessment of the adaptation of cultivars in new planting areas, prediction of flowering dates of parents in hybrid-rice seed production, evaluation of ideotypes in rice breeding, and input-output economic analysis. Options for further improvement of DRESS are suggested.
