Food security has a bearing on national development and people's livelihoods is an important guarantee of social stability for development. The problems arable land abandonment non-grain are becoming more serious, food difficult to guarantee, which will seriously hinder the forward China's society economy. Taking Ruijin City Jiangxi Province as example, this study calculated level in respectively from two aspects, explored spatial differentiation law farmland hilly mountainous areas southern by using autocorrelation cold hot spot analysis methods, causes Gannan were revealed methods Geodetector factor detection interaction detection. Conclusions study: (1) City, abandoned area was 1216.73 hm2, rate each village ranged 0.01% 50.62%, comprehensive 4.90%; 2937.27 100.00%, 11.83%. (2) phenomenon certain clustering driving effect space. Globally, phenomena positively correlated, with global Moran's I being 0.05, 0.73. (3) Whether or not affected combination socioeconomics, natural resources, farming conditions, economic location, elevation, degree contiguity, population density dominant factors. concentration field regularity, per capita increased variability Gannan. occurs socio-economic conditions proportion paddy fields, transfer price, area, urban-rural gradient land, price transfer, interact other, tendency be planted crops serious.
