Abstract

Abstract:

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.

Key words: cropland, potential productivity, upper reaches of the Yangtze River
