1运用卫星数据和来自国家森林清查的野外数据进行全国森林变量估计显示文摘瑞典约有55%的土地面积被森林所覆盖。目前,瑞典的森林覆盖没有统一的和地理学上明晰的描述。现存的独立性数据源是Landsat TM和SPOT HRV卫星数据、地图蒙片(map mask)和森林清查样地。它们在一起,使森林变量(如材积和林分年龄)的计算机估计成为可能。这些估计的精确度在像素水平上是低的,但在林分水平上较高。在规划木材资源应如何加以利用或出于监测目的时,这类基于栅格的森林数据对政府来说是有帮助的。本文描述了以有效成本建立森林变量估计全国数据库的生成流程。我们在林分水平上评价了瑞典西南部某地森林变量估计的精确度。结果表明,总材积估计的整体均方根误差为33%,年龄估计的整体均方根误差为23%。Heather Reese Mats Nilsson Tina Granqvist Pahlén Olle Hagner Steve Joyce Ulf Tingelf Mikael Egberth Hkan Olsson 王胜 2003AMBIO-人类环境杂志2003,32,8:4
