摘要
在地理信息系统(GIS)支持下,以Overlay模型得出的土地资源单位为评价单元,以二次开发的主成分模型、层次分析模型和综合评价模型为方法,以土壤类型、土层厚度、土壤有机质含量、土壤pH值、土壤速效硼含量、海拔高程、坡度为评价因素,评价得出南丰县土地资源中蜜桔种植适宜一等地有12783.03hm2,二等地有26844.36hm2,三等地有42853.51hm2。
Using the land resource unit as the evaluation unit and soil type, soil thickness, soil organic matter content, soil pH value, soil effective B content, elevation and slope as the evaluation factors, supported by Geographic Information System (GIS). the land resource suitable for planting of Nanfeng-Miju was evaluated. The result showed, there is land resource in Nanfeng County suitable for planting of Nanfeng-Miju with first grade 12 783.03 hm 2 , second grade 268 844.36 hm 2 and third grade 42 853.52 hm 2.
