Analysis of People's Feeling about Open Spaces in Sapporo (III)

Structure of Contentments with Open-space Functions

Abstract

This paper intends to clarify firstly the structure of people's contentments with functions of openspace, and secondly, the factors which influence on people's contentments in residential area. For this purpose, several multivaliate analysis methods were applied to the data of Sapporo open-space survey in 1974.
The main results obtained are as follows:
1) The measured contentments with functions of open-space were intercorrelated and were analysed by means of the principle component analysis. The first component was interpreted as the generality of open-space evaluations.
2) After varimax rotation of principle factors (by the principle factor method), following 3 common factors were identified:
F I Useability of open-space for recreation
F II Amenity (mainly beautifulness and natural condition)
F III Conservation of residential environments (mainly safety and health)
3) The result of regression analysis showed that F II was most important for people's total contentment among 3 factors.
4) From the results obtained by the quantification analysis proposed by Dr. C. Hayashi, the most influential determinant of F I, F II and F III was “sufficiency of parks (exclude children's park)”, “% of tree covered area” and “land use” or “population density” respectively.
5) The author could point out the importance of distinctions among following 5 open-space evaluations: evaluations of individual functions, totality of open-space functions, general factor, 3 common factors and synthesized rank of 3 common factors.
