The Effect of Differences in Landscape Pattern of Water and Green Give the Ecological Network by Landscape Ecology with Middle Resolution Satellite Images

: Comparison of the Five Cities where a Keystone Species of Small Species of Picidae

Abstract

We revealed the effect of differences in landscape pattern of water and green give the ecological network by landscape ecology with middle resolution satellite images in five cities of Asia and Europe. We understood the distribution of green and water areas by landscape ecology approach, and created 4 indicators. We performed the extraction of foraging and nesting environment as indicator species of small species of Picidae for the ecological network. Ties of the patch (adjacent probability) and the variance of the patch (communicability) have an effect on the ecological network. It is considered that rather than increasing the green and water area simply, and distributing them around the primary core satellite is also effective.
