摘要： 小麦和油菜是我国非常重要的两种大宗作物,它们的空间格局变化历来备受关注。利用1980 -2014年间小麦、油菜的面积数据,以省级行政区为研究单元,采用Pearson相关系数和GIS空间几何重心分析技术,结合同期作物之间的竞争性用地关系,对油菜和小麦的空间分布格局及其变化特征进行分析。研究结果表明:我国小麦近三十年空间格局的总体变化不明显但是省际分布特别不均衡,其分布重心一直位于河南省境内；油菜的面积重心自1980年以来从湖北省境内不断地向南推移,目前分布在湖南省境内。受同期作物之间竞争性用地关系的影响,在陕西、青海、湖北、湖南、四川等地,油菜、小麦的面积变化表现出明显的“消-长”关系,彼此呈显著负相关。

Abstract: Wheat and rape are the two important staple crops in China, their spatial pattern change draws wide attention. Area data of wheat and rape from 1980 to 2014 were used, provincial level administrative region was taken as the study unit, combined with the rivalrousness of similar growth cycle crops, the spatial pattern and its change of wheat and rape were studied by the method of Pearson correlation analysis and GIS spatial geometric center of gravity analysis. The results showed that: the change of spatial pattern of wheat in the past 30 years was not significant, but the provincial distribution was unbalanced, the distribution center of wheat was always located in Henan Province; the distribution center of rape was southward from Hubei since 1980, and it is now located in Hunan. Affected by the interspecific competition of crops with similar growth cycle, the area variation of rape and wheat in Shanxi, Qinghai, Hubei, Hunan and Sichuan showed a significant“growthdecline” relationship, which was significantly negative correlated with each other.
