An integrated management planning system for multiple-use of forests

Abstract

An integrated management planning system is developed for a large scale forest land use allocation and multiple-use management of regional forests, based on the results of forest functions evaluation. Two models are included in this system : one is an integer linear programming formulation that optimizes the spatial layout of a forest land use allocation for providing timber, soil and water conservation, environment protection, and recreation ground, and the other is a multiple objective programming formulation that maximizes the outputs for a forest region, and minimizes the inputs, over planning period. The results obtained lead to a valid land use assignment and effective planning, based on a geographic information system (GIS) for the whole forest region. The system was applied to the Tokyo University forest in Chiba. The results demonstrated that this system is a very efficient tool for making multiple-use management plan.
