Abstract: In order to study different development models of under-forest economy,a comprehensive benefit evaluation system of under-forest economy was established by analytic hierarchy process on the basis of questionnaire survey,field visit and data provided by departments.And four under-forest economic development models were analyzed and sorted in Chishui.The results suggested that forest tourism model had the best comprehensive benefit (benefit value 0.9126),followed by under-forest planting model (benefit value 0.3461),under-forest breeding model (benefit value 0.1218).And the worst one was collection and processing model of forest products (benefit value 0.0299).Therefore,according to the principle of emphasis focusing and overall planning,the local government and relevant departments should steadily promote forest tourism,change their mentalities to develop under-forest planting,manage under-forest breeding in moderate size,and innovatively develop collection and processing of forest products by following the current under-forest economic development and the advantages of ecological resources.
