A Study On Critical Land Use Distinction Application Technique With DEM Support

A Human-Geography System with interaction between Human activity and naturalenvironment in-degree depends on land-using type and degree of human being. Being one ofenvironment sensitivity elements, land use occupancies consequence of environment study inmonitor and sustainable development. Because it is affected by physical geography and humanbeing society activation, land resource research is one of cores of resource and environmentresearch. With the in-depth research of land resource sustainable development, the study oninterveinning land, fragility land and edge land has become broad recognition, which is the key ofland resource sustained use.The application technique study on Critical land use distinction with DEM support justresearches interveining land edge land, it will Provide a strongly technology measure for landresource rational use. The study on critical land use is the key of land resource use in reason,therefore, it has far-reaching meaning for land resource sustainable development. The whole thesishas four sections:l. present Study of critical land use2. The theory of Critical land use distinction application technique study with DEM support.3.
