Abstract:

By analyzing the temporal and spatial changing of rapeseed production in Sichuan Province in 1988-2017, the paper aims to provide certain references for further stabilizing the planting area and optimizing the regional distribution. Based on the analysis and arrangement of rapeseed production data, the regional distribution and superiority differences were quantitatively calculated by using the method of regional gravity center analysis and the method of comparative advantage index. From 1988 to 2017, there was a positive correlation between the total yield and the planting area of rapeseed in Sichuan Province, and the rapeseed yield increased faster than the planting area, rapeseed production was unevenly distributed among and within regions. The total yield of rapeseed was directly affected by the planting area and the yield per unit area. The production center of rapeseed in Sichuan Province was basically stable from 1988 to 2017, and the main production area of rapeseed migrated from the Chengdu Plain to northeast Sichuan, and expanded to the south of Sichuan. Combining with the analysis results, Sichuan Province should pay attention to rapeseed production layout planning, take full advantage of regional comparative advantages, strengthen the investment of infrastructure construction, promote rapeseed cultivation on a large scale, actively introduce agricultural scientific and technological talents, and popularize the new rapeseed varieties with double-low, high yield, multi-resistance and wide adaptability.

Key words: Sichuan Province, rapeseed production, temporal and spatial changing, pattern feature, center of gravity
