摘　　要：使用地理信息系统(GIS)与数学模型集成技术,以福建省现状林地、果园、茶园、牧草地、荒草地、沙地以及裸土地为评价对象,建立了评价因子空间及属性数据库。使用250m栅格为基本评价单元,对福建省主要桉树树种土地适宜性、质量进行评价。结果表明,主要受地域热量状况及低温冻害的制约,福建省桉树树种及其无性系适宜用地资源主要分布于闽南沿海地区和闽中、闽西和闽北内陆低海拔地区。Integrated with GIS and mathematical models,a spatial and attribute geodatabase was built including present forest land,orchard,tea garden,meadow,uncultured grassland,sand lot,and bare land in Fujian province. Adopting a grid resolution at 250m,suitability and quality of land resources for growing Staple Eucalyptus was evaluated. The result showed that,mainly constrained by zonal heat condition and extremes of cold,land resources suited for growing Staple Eucalyptus species are distributed mostly in the cos...
