Spatial Pattern and Influencing Factors of Agricultural Employment Accessibility in Karst Area:A Case Study on Huangping County
Accurately measuring the spatial pattern and influencing factors of agricultural employment supply and demand in karst area is an important guarantee for achieving local and nearby employment in the region.Taking Huangping county as an example,using the improved Gaussian two-step moving search method and relying on the actual transportation network,based on the supply and demand matching,the agricultural employment accessibility was calculated at the administrative village scale on the basis of the number of available employment positions and the number of employment demands in the residential area.Combining the spatial autocorrelation analysis and the Gini coefficient,the spatial differentiation characteristics of accessibility were explored,and the main influencing factors of spatial differentiation were detected using geographic detectors.Research results are as follows.(1)There is a significant difference in the supply-demand ratio of agricultural employment among administrative villages in Huangping county,with a significant mismatch between the supply and the demand.The accessibility of agricultural employment shows the characteristics of high accessibility concentration in the central region,general accessibility distributed around high accessibility in the northwest region,and low accessibility concentration in the southeast re-gion.(2)The spatial differentiation in the agricultural employment accessibility in Huangping county is obvious,with a positive correlation in distribution.The accessibility of agricultural employment in the residential area shows significant or great disparities,with strong internal imbalances.(3)The fragmentation degree of cultivated land has a significant impact on the spatial differentiation of agricultural employment accessibility.At the same time,the in-teraction among economic development,population situation,terrain and topography,degree of fragmentation of cultivated land,and transportation situation has a significant impact on the spatial differentiation of agricultural em-ployment accessibility in Huangping county.
