Spatial differentiation and driving forces behind non-grain agricultural production in the low mountain and hilly areas of southern Jiangxi:a case study of Xunwu County
In order to describe the spatial distribution difference of non-grain agricultural production structure in low mountain and hilly areas of southern Jiangxi,the cultivated land protection and scientific control of non-grain should be strictly implemented.Taking Xunwu County as an example,geographical detector factor detection,interaction detection and other methods were used to reveal the spatial differentiation characteristics and causes of non-grain agricultural production in the low mountain and hilly areas of southern Jiangxi to provide a policy formulation reference for effective prevention and control of non-grain production in such areas.The results showed 19.42%non-grain agricultural production in Xunwu County in 2020,and cultivated land was mainly converted into forest and garden land.Spatial differentiation of non-grain production was significantly related to the four dimensions of cultivated land background conditions,natural resource endowment,economic location,and policy environment,while topography,farmland infrastructure,and cultivated land concentration were important driving factors behind the spatial differentiation.The same driving factors have greatly different driving directions for the development of forest and fruit production and facility agriculture on cultivated land.The interactive relationship between factors of non-grain production is a two-factor enhancement or nonlinear enhancement.According to the spatial differentiation characteristics of agricultural non-grain production structure in the hilly area of southern Jiangxi,it provides a reference for the classification monitoring and objective disposal of non-grain,and provides suggestions for optimizing the allocation of agricultural resources and the spatial layout of agricultural production in the hilly area of southern Jiangxi.
