摘 要: 在土地利用分区的基础上 ,把长江上游典型区———四川省彭州市的耕地土壤资源分为3类农业利用亚区 :平原亚区、丘陵台地亚区和山地深丘亚区 ,采用目前国内外应用最广泛的“农业生态区域法”估算该区水稻、小麦、玉米、甘薯和土豆 5种作物的光温潜在产量 ,并根据各区的土壤属性 ,计算了土地生产潜力 。 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, sweet potato and potato were 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.
