Abstract
[Objective] The aim was to study the characteristics of spatial agglomeration law of arable land quality of Guangshui City at county and township scale based on the spatial autocorrelation of Moran's I analysis method.[Method] Taking Guangshui City of Hubei Province as the study area,the national natural land quality index,the land use index and economic index as spatial variables,and farming spot as a space unit map spatial autocorrelation analysis,the characteristics of the spatial differences of arable land quality from the county and township scale were analyzed based on the spatial autocorrelation of Moran's I analysis method.[Result] Spatial distribution of the quality of arable land in Guang-shui City presented a certain clustering rules,quality of arable land in'North central' was high,'Northwest corner' was relatively low,the rest were in the middle level and relatively concentrated.The quality of arable land in Guangshui showed a strong spatial autocorrelation at the county and township level,indicating that the spatial pattern showed a strong agglomeration situation.Moran's I value of arable land quality index showed the national economic index,national utilization index,national natural index decline characteristics both at the county and township scale,and all the index showed a significant positive correlation of the spatial agglomeration.[Conclusion] The spatial difference of land quality at different scales has certain characteristics of sensitivity and internal differences,and differences of arable land quality feature space can provide an impor-tant reference for land consolidation,high standards of basic farmland.关键词
