Method of the Classification of Open Spaces According to their Actual Management Types

Abstract

Open space management has increasingly played an important role in proportion to the rapid increase of newly constructed open spaces. The purpose of this study is to consider how to classify such open spaces according to their types of actual management situation in order to present the basic knowledge for the planning of optimal future management form.
The authors apply here the method of Quantification Theory III to the classification of 27 open spaces distributed on the sites of research organizations in the Tsukuba Science City, about 60 km north of Tokyo, as a case to discuss. Quantification Theory III seems to be useful for the comprehensive and objective classification of open spaces according to their management types by using the data obtained from the questionnaire survey since they contain a lot of different management forms and factors including both qualitative and quantitative aspects and they can be hardly classified without such multivariable analysis.
Result of the analysis suggests that the combination of Axes I and II are useful for the classification of open spaces. Items showing the opposition of categories on Axis I generally indicate“the characters of management objects”, while those on Axis II indicate“the characters of management activities”
Classification of open spaces according to their management types can be performed through the adjacency of sample scores on Axes I and II taking the ordination of categories in each open space into account. As a result of this study 6 groups are classified under the consideration of management types as shown in Fig. 2 and Table 4.
Such kind of groups will be used as a fundamental information for the planning of optimal open space management.
