联合国世界气象组织、世界粮农组织以及荷兰农业大学研究生基金会、荷兰世界粮食研究中心等于1983年11月21日—12月3日在荷兰瓦赫宁根举办了一期名为“农业产量模拟:天气、土壤和作物”的国际训练班。作者参加了该训练班的学习,现将荷兰的农业产量模拟方法简要介绍如下。一、概况目前,随着农业基础理论研究的深入和计算技术的发展,模拟方法正在农业研究中逐步得到应用。农业产量模拟方法主要有两种。一种是经验统计方法,即通过统计手段,建立农作物产量与外界条件(主要是天气)之间的关系。另一种是动态模拟方法,考虑到作物生活在土壤-作物-大气这一复杂交
The United Nations World Meteorological Organization, the World Food Program and the Netherlands Agricultural University Graduate Fund, the Netherlands World Food Research Center, held in Wageningen, The Netherlands, November 21-December 3, 1983, entitled “Agricultural Production Simulation: Weather, Soil and Crops ”International Training Course. The author participated in the training course, now Netherlands agricultural yield simulation method is as follows. I. Overview At present, with the deepening of the research on basic agricultural theory and the development of computing technology, simulation methods are gradually being applied in agricultural research. There are two main methods of agricultural production simulation. One is the empirical statistical method, that is, through statistical means, to establish the relationship between crop yield and external conditions (mainly the weather). The other is a dynamic simulation method, taking into account crop life in the soil - crop - the atmosphere of this complex
