Abstract:

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.

Key words: forest land, sub-compartment, boundary, topographic factor
