| 摘要: |
| 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。 |

| Abstract: |
| This article advances an idea about crop-climatic three-dimensional space sliding over analogical analysis and crop-climatic classification.At present the facts are as follows:in crop-climate classification the target is not complete and can not show the difference of distribution in wa- ter and heat during each period of the course of crop growing,when the computational method of assemblyical analysis is used in all places the critical period and main factors that influence crop growing were trea- ted all ... |
