Evaluation based on a vegetation-landscape analysis about the cultural services of urban green-spaces

Abstract

For the purpose of analysis and evaluation on the ecosystem's cultural services of urban green-spaces, several field researches (tree census, vegetation-landscape investigation and hemispherical sky photography) were carried out on streets and parks existing in “Yokohama-Minatomirai 21”, and those obtaining data were analyzed statistically. The vegetation-landscape units (type and subtype) distinguished by a table manipulation for the urban green-spaces classification were divided into four main groups by a correspondence analysis. The landscape elements which would characterize each main group were identified by an independence test and a residual analysis. Based on those statistical analyses, we have evaluated about the positive psychological effect by which the urban green-spaces bring people “comfort” and “relief” which are a part of the cultural services. Moreover, the means to create the urban green-spaces, by which the fascination of regional landscapes would upgrade, were proposed.
