【内容概述】

综合应用变异系数、地理联系率、区位熵等区域差异分析方法对山东省1999年以来地级市尺度的粮食生产和经济发展地域格局变化特征进行了联动分析。研究发现:山东省粮食生产经历了一个“上升-下降-上升”的波动过程;地域差异增大,尤其是1995年后,粮食生产与经济发展、人口分布发生明显的空间分异;黄河以北地区,特别是鲁西北地区在全省粮食生产地域分工过程中扮演着越来越重要的角色,日益成为山东省粮食生产核心区域。最后 ,结合耗散结构理论,分析了山东省粮食生产地域格局变化的驱动因素,并提出了相关建议。

THE REGION PATTERN OF CHANGES IN FOOD CHARACTERISTICS AND ANALYSIS IN SHANDONG PROVINCE

ABSTRACT
Comprehensive application of variation coefficient, geographic location entropy contact rate, the regional difference analysis method of Shandong province since 1999 locally administratered level of grain production scale and regional economic development pattern change characteristics of linkage analysis. Findings: Shandong grain production experienced a "rise - down - rose" wave process, Regional differences, especially after 1995, grain production and economic development, population distribution pronounced space differentiation, North of the Yellow River region, particularly in the area of grain production Lu Xibei division plays a more and more important role in Shandong province, becoming the core region of grain production. Finally, combined with the dissipative structure theory, this paper analyses the regional structure change of grain production in Shandong province, the driving factors and puts forward relevant Suggestions.

Key words: Food production; Economic development; Geographical pattern; Shandong Province
