摘要：林地小班(简称小班)是森林资源规划设计调查、统计和经营管理的基本单位。小班调查是林业重要的基础性工作,小班边界和地形因子是小班调查的重要内容,快速、准确地获取小班边界和地形因子,对编制森林经营方案、指导林业生产具有重要作用。通过梳理基于遥感影像、数字高程模型(DEM)、遥感影像结合DEM的小班边界计算机自动提取方法和基于DEM的小班海拔、坡度、坡向、坡位等地形因子计算机自动提取方法的研究与应用现状,指出目前存在的问题,提出了今后研究的建议。
Forestland sub-compartment(referred to as sub-compartment)is the basic unit of forest resources planning,design,investigation,statistics and management.Sub-compartment survey is an important basic work in forestry,and sub-compartment boundary and topographic factors play a key role in sub-compartment survey.Therefore,it is very important to obtain the boundary and topographic factors of sub-compartment quickly and accurately for compiling forest management plan and guiding forestry production.Through collation of the research and application status of computer automatic extraction method of sub-compartment boundary based on remote sensing image,digital elevation model(DEM),remote sensing image combined with DEM,and computer automatic extraction method of elevation,slope,aspect,slope position and other topographic factors based on DEM,this paper pointed out the existing problems,and provided some suggestions for future research.
