摘　　要：选取营养元素和氧化物为评价指标,结合G IS空间技术对四川省内江市双桥乡的土壤质量进行了分区评价,在优势区可少施或不施钙镁磷肥,而在局部区域适量施钾肥。劣势区钙缺失严重,因而应尽量少施磷铵,补充含钙磷肥,可适当施用黄铁矿、铵态氮肥、有机肥等,促使钙的转化释放。This thesis selected nutritional elements and oxides for evaluation index, and made a research on soil quality partition and assessment by GIS methods in Shuangqiao rural, Neijiang, Sichuan. In superior regions, little fused calciummagnesium, phosphate may be applied, but potash fertilizer should be properly used in the local area. In inferior regions, calcium loss was serious, so little ammonium phosphate fertilizer but pyrite, ammonium-nitrogen fertilizer, organic fertilizer may be properly used for transformation and release of calcium.
