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
