JOURNAL FREE ACCESSThe 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.View full abstractDownload PDF (812K) -

On the influences of tread-pressure and mowing on the growth of Japanese lawn grasses varietiesFumio KITAMURA1965 Volume 28 Issue 3-4 Pages 12-17
Published: March 31, 1965
Released on J-STAGE: July 19, 2011
JOURNAL FREE ACCESSThe experiments were carried out to know the influences of tread-pressure and mowing on the growth of Japanese lawn grasses varieties (No-shiba, Chu-shiba, Korai-shiba I, Korai-shiba II, Korai-shiba III, Kara-shiba, Chosen-shiba, Hime-shiba, Meyer Zoysla, Emerald Zoysia, Zoysia matrella (native to Philippine) and Z. tenuifolia (native to Guam I.)), and the following results were obtained.
(I) Generally, Japanese lawn grasses were comparatively strong to the tread, but the extremely small varieties were somewhat weak. In case of the moderate tread-pressure (I-5 times/day), as a rule, the length of stolons, the numbers of stolons, nodes, leaves and roots of Japanese lawn grasses varieties were increased, and their turf grew thick. While, in case of the over tread all decreased.
(2) Japanese lawn gras3es varieties were comparatively strong to the mowing. In case of the moderate mowing (the larger varieties-I time/2-4 weeks, the smaller varleties-I time/I-4 weeks), as a rule, the numbers of stolons, nodes, leaves and roots were increased, and their turf grew thick. While, in case of the over mowing, all decreased.View full abstractDownload PDF (816K) -
On the influences of sunbeam and the effects of three nutrient elements on the growth of Japanese lawn grasses varietiesFumio KITAMURA1965 Volume 28 Issue 3-4 Pages 18-22

JOURNAL FREE ACCESSThe experiments were carried out to know the influences of sunbeam deficiency and the effects of three nutrient elements on the growth of Japanese lawn grasses varieties (No-shiba, Chu-shiba, Koraishiba I, Korai-shiba I, Korai-shibal II, Kara-shiba, Chosen-shiba, Hime-shiba, Meyer Zoysia, Emerald Zoysia, Zoysia matrella (native to Philippine) and Z. tenuifolia (native to Guam I.)), and the following results were obtained.
(1) Japanese lawn grasses varieties were weak to the sunbeam deficiency. Under the deficiency, their weight, and the numbers of stolons, nodes and leaves were decreased. While, they overgrew at first sight, namely, length of leaves was increased, and, in case of the moderate deficiency, lenght of stolons was increased.
(2) In case of want of nitrogen element, the growth of all varieties was worst, and, when phosphorus element lacked, it was somewhat better than the former. In case of want of potassium their growth was comparatively good. When three elements were given, the growth was best.View full abstractDownload PDF (657K) -

JOURNAL FREE ACCESSThe table presented here involves 58 shrubs and trees, which may give a convenient source for gardeners who want to know seasons and durations of fruits and berries of ordinary garden shrubs and trees being beautiful.
We completed this study in the early spring of 1962 after a two-year-study with close observations and photographing in the parks, gardens, firms and other facilities around Tokyo.
The plants listed are species of Japanese and Occidental origin, frequently seen in our gardens and with their fruits and berries having considerable effects of colors and shapes in designing landscapes.
The results obtained in our observation were as follows:
1. Length of beautiful period of fruits.
Remarkably short. cabout 20 days 4 species out of 57
Relatively long. more than 3 months 12 species
Long enough for more than 5 months 6 species
Others 36 species
2. Their admirable seasons for each shrub and tree.
Colored before June 7 species
Admirable during the summer months (July and August) 5 species
Colorful after December 4 species
Rest of them are tinted from the early fall 42 species
3. Classification of fruit's colors.
Red and crimson 62%
Yellow (including orange) 19%
Bluish purple and other dark tones 5-7%View full abstractDownload PDF (409K)
