摘　　要：采用2000、2006年的TM影像作为数据源,利用GPS、全站仪等仪器,采取典型、随机抽样方法调查了山东黄河流域378个林地抽样点,利用监督分类法、专家分类法和G IS技术对遥感影像进行分类和建模。研究表明,2000、2006年的山东黄河流域森林覆盖率分别为21.40%、25.60%;森林主要分布于鲁中南山地、丘陵地区;落叶阔叶林和温性常绿针叶林是流域地带性植被,其中杨树、侧柏和刺槐是主要造林树种,森林垂直分布较为明显;森林蓄积量集中分布于鲁中南地区,流域的森林资源及其蓄积量2006年比2000年的分布相对均匀。TM images of the Yellow River Basin in Shandong Province in 2000 and 2006 were selected as the basic data sources. A total of 378 forest sample points were collected by the method of typical and random sampling using GPS instruments and electronic total station. Classification and modeling of the 35f images were conducted by the supervised classification method, expert classification method and GPS techniques. Results indicated that the forest coverage rates were 21.4% in 2000 and 25.6% in 2006. The forests were mainly distributed in the south central mountainous regions and hilly areas of Shandong Province. The deciduous broadleaf forests and temperate evergreen coniferous forests were the zonal vegetation of the Yellow River Basin in Shandong Province. Poplar, oriental arborvitae and locust were the main afforestation tree species, arid the vertical distribution of forests was more obvious. The forests in the Central South Region of Shandong Previnee exhibited the highest volume. Gh.erall, the distribution of forest resources and volume in 2006 was more uniform than that in 2000.
