Analysis of spatiotemporal changes and influencing factors in vegetable production in Guangxi
Based on the production data of vegetable regions,cities,and counties,this study uses methods such as indus-try concentration index,center of gravity shift,and advantage index to investigate the spatiotemporal changes in vegetable production in Guangxi.The grey relational analysis method is used to analyze the influencing factors of vegetable yield in Guangxi.The results indicate that the vegetable planting area,yield,and unit yield level in Guangxi have been increasing year by year,but there is still a significant gap between the unit yield and the national average.The concentration of vege-table production is relatively high,and the overall focus of yield is shifting southward.The vegetable production capacity of counties has been improved to varying degrees,and the number of counties with comparative advantages is gradually increasing.The high influencing factors of vegetable production include per capita agricultural operating income of rural residents,added value of the primary industry,mileage of graded highways,vegetable sowing area,vegetable yield per unit area,vegetable output value,annual sunshine hours,and annual average temperature.Based on the above analysis,the authors propose that development policies for the vegetable industry should be formulated according to spatiotemporal changes and relevant influencing factors.
