The land resource in Pengzhou, Sichuan Province was divided into 3 agricultural zones,i.e.,plain subregion, hilly and mountainous subregions based on division of land use.The light-temperature production potentiality of paddy rice, wheat, corn, sw eet potato and potato w ere evaluated using Kassam-Wageningen method.Moreover, the potential productivity of cropland was evaluated according to the property of soil in different subregions.In response to the result of evaluation, measures and suggestion were presented.
