Abstract

Forestland is the carrier of forest resources and the basis of forestry development,and the forestland quality classification is an important index of quality analysis and evaluation. In combination with forestland protection and utilization planning in Shehong county of Sichuan province, and by using analytic hierarchy process method,the soil thickness,soil type,slope degree,slope,aspect,slope position and traffic location were chosen as the main 6 factors of classification of forestland quality grade,and a forestland subcompartment was chosen as the unit. Combined with the GIS spatial analysis method, the forestland were divided into Ⅰ, Ⅱ, Ⅲ, Ⅳ and Ⅴ grades, and their forestland area was 0, 44.22 hm², 5 437.46 hm²,41 089.05 hm²,76.36 hm², respectively accounting for 0,0.09%,11.66%,88.08% and 0.16% of the total forestland. This study had an important significance on forest protection and scientific,unified and reasonable management of forest resource.
