摘要:

寻找有效的方法研究小麦生产的时空特征,对于江苏省小麦生产的宏观调控及管理具有重要意义。提出了一种研究小麦生产时空特征的新方法,这种方法在对小麦综合比较优势进行分析的基础上,构造三个基本模型,完成对综合比较优势的定量分析的规范化评估,从而实现从不同的侧面对江苏省各地级市小麦生产的综合比较优势时空特征的动态态变化进行研究,并给出有用的结论。研究表明,江苏省小麦生产的综合比较优势受多种自然及非自然因素的影响,除了有一定的统计规律外,也表现出相当程度的随机性,但加强农田基本建设及抵制自然灾害的能力、提高小麦生产的科学管理水平是提高小麦生产的综合比较优势的重要途径。

Abstract:

This paper presents a new method for analyzing time and space variation of wheat production in JiangSu province with three basic models, which is based on normal analysis for comprehensive comparative advantages (CCA) of wheat and satisfies control and management requirement of wheat production in this province. The results indicate that the normal CCA is influenced strongly by several natural and non-natural factors and can be used for scientificmanagement of wheat production. Thus, reasonable distribution adjustment, land infrastructures construction and scientific management of wheat production are major factors to increase wheat production level in this province.

Key words: wheat production , comprehensive comparative advantages, normal analysis , time and space variation;scientific anagement
