中文摘要:本文利用模糊聚类方法对早稻各生育时段农业气象条件进行分类;并用一组农业气象模式,在计算机上作各种组合条件下的早稻生长状况和产量模拟试验;构造影响指数Ca和C作为农业气象条件定量评估的依据;通过计算机终端输出早稻生长状况和产量动态监测结果,提供农业气象信息服务和早稻生产决策方案。此外,还用决策分析方法讨论了上海早稻适宜的栽插密度。
 
ASSESSMENT MODELS FOR AGROMETEORO-LOGICAL CONDITIONS OF EARLY RICE
Abstract:Agrometeorological conditions for early rice growth at differentstages are classified by Fuzzy cluster analysis.A set of agrometeoro-logical models are used in simulation experiments on a computer for the growth and yield under possible combinations of the conditions. Influ-encing indices Cα and C are constructed as the criterion for the quan-titative assessment of agrometeorological conditions. The early rice growthand dynamic moditoring of yield from the terminal output provide infor-mation service and schemes for decision of early rice planting. Besides,the planting density in the area of Shanghai is discussed in terms of de-cision analysis.
