Abstract
This study is present the evaluation method of the ecological network in urban area by using remote sensing and geography information system in order to discuss conservation of the regional ecosystem. The small-scale green space such as wooded backyard is made out by interpretation of high-resolution satellite image and analysis of digital surface model and digital terrain model in urban area of Suginami city in Tokyo. The suggested habitat evaluation method of Japanese Pygmy Woodpecker, an indicator species of ecological network, is verified by field investigation. In addition, this paper proposed evaluation of the future scenarios such as decrease of private green space in study area in order to study effective green space planning.
