| 摘 要： | 借助地理信息系统(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、沙地及裸土地为评价对象,以250m×250 m栅格为评价单元,在利用数学高程、趋势面分析等模型探讨并建立初选评价因子空间及属性数据库的基础上,采用主成分分析结合相关分析和理论探讨筛选建立主要桉树土地适宜性评价因子体系,借助极限指标比较法、加权指数和法等对福建省主要桉树树种土地适宜性和质量进行评价。

| Abstract: | Based on the GIS and mathematical model,forest land,orchard,tea garden,meadow,uncultured grass land,sandlot and bare land in Fujian Province were evaluated,with evaluation unit being 250 m×250 m grid.The spatial and attributive database of original selection evaluation factors were established and selected by principal component analysis and correlative analysis.Land suitability and quality of major eucalyptus species in Fujian Province were evaluated by the methods of extreme limit index sign comparison and weighted aggregative index number. |
