A Study on the Method of Quantitative Analysis on Open Space Effects and Its Application to Evaluation of Land Use Control in Urban and Suburban Areas

Abstract

This study aims to discuss the method of quantitative analysis on environmental conservation effects of open space, to examine the relationships between the effects and land use control, and to discuss how the land use control ought to be. The case study areas were selected in urban and suburban areas (Miyakogawa river basin, Chiba, Japan). Basic methods were quantitative analysis of effects and impact simulation for land use control, using Geographical Information System. Based on the results of this study, it was clarified that quantity of environmental conservation effects is affected by distribution of forest land, rice field and paddy field in upper waters. Regarding land use control in this type of areas, open space conservation in suburbs and upper waters and reclamation of wet land such as rice field are necessary.
