本文针对目前作物气候区划方法中存在的问题如:指标笼统,未能反映水、热等在作物生育进程中各阶段分配差异,以及将各地影响作物生育的关键时期、关键因子等同看待进行聚类分析等,提出作物气候三维空间滑移相似分析及其区划的设想,并在河北石家庄地区以16个县范围,新疆83个站点范围内进行试算,已取得初步成果。本文着重阐述其提供作物生育进程与气候环境之间适应性的信息;历年气候变化对产量波动影响效应的信息;地域性规律等三维空间信息的数学模型及其特征曲线,并据此进行滑移相似计算,在相似分析基础上对作物气候区划的方法及步骤,作了探讨和比较。
In this paper, the current crop zoning method of existing problems such as: indicators are general, failed to reflect the water, heat and other stages of crop growth in the distribution of differences, and will affect the crop around the critical period of development, the key factors equal to the clustering Analysis and so on, put forward three-dimensional spatial slide similarities analysis and zoning assumptions, and in Shijiazhuang, Hebei Province in 16 counties, 83 sites in Xinjiang within the trial, has achieved initial results. This article focuses on providing information on the adaptability between the crop growth process and the climatic environment; information on the effects of climatic changes on output fluctuations over the years; and the mathematical model of the three-dimensional spatial information such as regional laws and their characteristic curves, Similar calculation, on the basis of similar analysis of crop climate zoning methods and steps were discussed and compared.
