The agricultural regional type and function are the key theoretical issues in agri-cultural geography research.Gully agriculture in the Loess Plateau is a new regional type of agricultural system with the coupling development of the modern gully human-earth rela-tionship.The study of its functional changes is of great practical significance for food security,rural revitalization and sustainable development of regional agriculture in the region of inter-est.This paper analyses the multifunctional change of gully agriculture in the Loess Plateau and its dynamic mechanism by using large-scale remote sensing data,topographic relief amplitude model,and spatial econometric model to understand internal implications for evo-lution differentiation at the basin level.The results show that:(1)The spatial concentration of production and supply function of agricultural products(APF)in the gully of the Loess Plateau gully is high,while the ecological conservation and maintenance function(ECF),employment and social security function(ESF),cultural heritage and leisure function(CRF)are relatively low.The four functions'spatial distribution has revealed an apparent regularity.(2)APF has been significantly enhanced,which is mainly distributed in point clusters and strips in the farming and pastoral areas in northern Shaanxi to the Yanhe river basin.The high-value ar-eas of ESF are clustered around the urbanized metropolitan circles and urban-rural stag-gered areas along the Great Wall.ECF is concentrated in areas with significant natural en-dowments and excellent ecological conditions.CRF is significantly higher in the municipal districts and the surrounding regional central cities.(3)There are noticeable differences in the gully agriculture regional function(GARF)evolution process due to the geographical envi-ronment and socio-economic development stages.In this regard,natural factors have tre-mendously affected APF,ESF,and ECF,while socio-economic factors greatly differ in the four functions.There are still differences in the driving mechanisms of modern gully agricul-ture evolution types;hence many critical policies in the Loess Plateau can directly affect the function evolution paths.The dynamic evolution of GARF can reflect the general law of rural human-earth system transition in gully areas,thereby providing policy ideas for high-quality development of agriculture in the Loess Plateau.
