摘 要 ：本文提出的适宜度理论和方法是一种描述作物与环境关系的定量方法。文中提出了两个新的概念:适宜度过程、环境因子变化过程适宜度。以此为基础,建立了一系列的适宜度模型及产量模型。将该理论及方法应用于分析定西春小麦生产,初步摸清了当地小麦产量长期低而不稳的规律,本文提出的春小麦产量模型具有明显的生物学含义并可用它在不同生长阶段对产量进行预测。经用1984、1986年的数据验证,模拟值与实测值分别相差8％、7.2％。

Abstract:In this poper.the theory and method of appropriate-measure (AM) dealt with a quantitative means describing the relationship between environment and crops. Two new concepts are put forward .including the process of AM and the AM of the process of the environmental factors‘variation for crops. Based on them, a series of models for the AM and the yield of crops have been built up. The theory was used for analyzing the production of the spring wheat in Dingxi, Gansu province and the regular pattern was found ou...
