摘要: 运用ArcGIS空间分析探究2000—2017年中国9大农业区农业机械总动力水平的空间分布,从省域层面分析各省(自治区、直辖市)(香港、澳门、台湾除外)地均农业机械总动力空间分布的演变特征,并运用皮尔逊(Pearson)相关性分析探究耕地变化和第一产业增加值变化与农业机械总动力变化的相关性。结果表明:2000—2017年,中国农业机械总动力水平快速提升,整体由“一强多弱”向“多强并存”格局演变,但省域发展不均衡,存在较明显的空间差异。农业机械总动力与第一产业增加值变化的相关系数为0.735,说明农业机械总动力的增长会带动第一产业增加值的提高,与耕地变化的相关系数为0.478。

Abstract: To explore the spatial distribution and evolution characteristics of China's total agricultural machinery power, ArcGIS spatial analysis and Pearson correlation analysis were adopted. The spatial distribution of total agricultural machinery power in nine agricultural areas from 2000 to 2017 were explored. The provincial (Hong Kong, Macao and Taiwan excluded) spatial evolution characteristics of total agricultural machinery power per hectare were analyzed, and the correlations within the changes of added value of the primary industry, cultivated land and total agricultural machinery power were determined. It was shown that the total agricultural machinery power increased rapidly in China from 2000 to 2017. The spatial distribution pattern in 9 agricultural areas varied from “one strong and many weak regions” to “multiple strong coexistence”. The development of total agricultural machinery power was not balanced among provinces. The correlation coefficient between the changes of total agricultural machinery power and the added value of the primary industry was 0.735, which indicated an obvious correlation. In other words, the increase of the total agricultural machinery power would promote the increase of the added value of the primary industry. The correlation coefficient between the changes of the total agricultural machinery power and the cultivated land was 0.478.

Key words: total agricultural machinery power, spatial distribution, evolution characteristics, correlation
