Studies on Shirakawa Park Planning with the Ekistics point of view

Abstract

The writer had researches on various greens in Kyoto about their recreational inducement and studied them with the hiearchy of Ekistics which proposed by Dr. C. A. Doxiadis, Greece, to establish an idea of the pattern of urban greens.
This study is prepared to relate greens and communities in each hiearchy with experimental logarithmic formula, and is assumed as follows.
I. A playlot (O.2ha) has below inducing tendency and relates with block (hundreds' families community)
logP=-1.2log+ (t²) +0.9
P: recreational inducement rate (%/year)
T: time distance (hour)
II. A children park (1ha) has a tedency shown below formula and relates' with neighbourhood.(about a thousand families community)
logP=-1.2log (t²) +1.1
III. Kyoto-Gyoen, boha large park, has a below tendency and relates with city.(tens thousand sfamilies community)
logP=-1.1log (t²) +1.5
Rdmarks
Time distancet is defined as above, and t² which is used in above formulas means an ecological distance such as t.m which has been shown as an index ecological distance of natural resort.
Recreational inducement rate P was also defined as effective percentage by Dr. Nagami in 1934.
