Temporal and Spatial Evolution of Vegetable Industry Specialization in Gansu Province
Using the methods of FLQ specialization measurement index and spatial autocorrelation,this paper described the spatio-temporal differentiation characteristics and spatial agglomeration effect of vegetable industry specialization in Gansu Province from 2000 to 2020.The results showed that the location entropy of the vegetable industry in Gansu Province was less than 1,the FLQ index was less than 0.4 during the study period,indicating that vegetable specialization was at the medium and low level.The number and spatial distribution of different levels of vegetable industry specialization in Gansu Province showed significant differences.For example,Gannan region has been at a low level for a long time,showing a continuous pattern of agglomeration distribution.The proportion of counties with higher specialization was only 12.64％,and concentrated in Longzhong region.The global autocorrelation MORAN's I index was positive,and the vegetable industry specialization had a positive spatial correlation,and there were different degrees of spatial agglomeration phenomenon.
