Abstract
Forest zoning system is expected to propose a new scheme of regional forest management. Applicability of GIS techniques for such new scheme was discussed based on the forest information system introduced in Mie Prefecture. The zoning system in Mie Prefecture is based on two categories of forest type, i.e. a production forest and an environmental forest respectively. For an environmental forest, a new thinning and management design called "Forest Environment Creation Project" was introduced. This project is conducted by full subsidy. The two major conditions are long term contract with certified forest association in 20 years and the total target area more than 30 ha. But it was satisfied only less than 40% area with over 30ha combined compartments without any small holders. According to the simulation with variable area constraints, it appeared 62% of target area grouped under the 10ha condition. Furthermore, alternatives of official support were demonstrated and unsolved future issues were discussed.
