都市近郊農村における里山林の管理・利用実態とその公益的機能に関する研究

Abstract

To clarify the relationship between the present status of the Satoyama forest and its multiple social functions in a suburban area, research was conducted in the Matono area, of Shingu Town, Fukuoka. Based on a series surveys, every forest was examined from 4 aspects; forest type (conifer plantation/broadleaved forest), land ownership (common/private), age and management situation, and the database sorted accordingly. We then evaluated the multiple social functions of the forest. The result were as follows; 1. Well-managed forests were few; and depended on forest type, 2. Multiple function uses were fully available only in 7% of total forest area. Especially, conifer plantations were evaluated low for stability of vegetation, amenity, biological diversity, and as a river water-source; suggesting the necessity to improve the forest structure. 3. From an interview with the forest owner, it became apparent that it would be impossible to manage both private and common forests for both their family interests and those of the community. Consequently, it was considered necessary that a linking system be established between the rural community and city dwellers for purposes of conservation to restore a sustainable environment and sane resources utilization.
