Structure of Contentments with Open-space FunctionsShyoichiro ASAKAWA1977 Volume 41 Issue 1 Pages 3-10
Published: December 15, 1977
Released on J-STAGE: July 19, 2011
JOURNAL FREE ACCESSThis 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.View full abstractDownload PDF (1232K) -

Analysis for the Stable Zones of Land UsesIsao NAKASE, Tadashi KUBO, Masami SUGIMOTO1977 Volume 41 Issue 1 Pages 11-22

JOURNAL FREE ACCESSIt became an important key around the urbanised areas how to control and preserve the aglicultural and forestry fields against to the urbanization. But, the land use plannings were mostly discussed and organized from the side of city and urban planning.
In flat areas, the growing patterns of urbanization also has no relations to natural land conditions. The land use plannings relate to natural land potentials are to be discussed and appropriate land use controls should be bring into practice.
In this study, the relation between the landscape changes and land use changes were discussed (figure1). Then the general ideas that explain the existing situations of land uses were proposed. Those are “adaptable” zone, “most adaptable” zone and “stable” zone. On the process. the land use items were divided into three groupes. The first is the forestry area, the second is the aglicultural area and the third is the urbanized area. Adaptable zones and most adaptable zones can be explain with the natural land conditions.
Stable zones can be determine through the dynamic balance of existing land use groupes.
Finally, the stable zones of every land use groupes were suggested by the slope degree of land in Osaka prefecture through mesh analysis. And the process of calculation of slope degree is shown in f gure 5.
The forestry areas are stable on sloped zonesand the slope degree is over 7. The aglicultural areas are stable on the sloped and flat areas and their slope degree is fom 0 to 8. But the zone of the slope degree from 0 to 4 can be more stable zones as rice fields and farm areas. But the flat areas (slope degree=0) were mostly urbanized and natural land uses were reduced.
Here the relation between land use and slope degree were discussed mainly. But there are more and more elements that relate to land use and we should find out more planning and analysing units that can cover the land use elements and natural elements.View full abstractDownload PDF (7804K) -
A Reconnaissance Method of Vegetation SurveyAkira KAMEYAMA1977 Volume 41 Issue 1 Pages 23-33
Published: December 15, 1977
Released on J-STAGE: July 19, 2011
JOURNAL FREE ACCESSSlope vegetation of cut and fill slopes on expressway, which have been seeded, make secondly succession. Phytosociological survey of the succession is important for the management of slope vegetation. Unfortunately, almost all of the techniques we are familiar with are time-consuming, involving plot studies. In view of the immediate need for information on the large roadside areas still unstudied in the expressways, the author thought it desirableto develop an analysis technique based on quick reconnaissance methods. A rapid technique makes it possible to visit a greater number of stands, thereby sampling a greater range of variability in a larger geographic area in less time. And the many data accumulated in a rapid survey necessitates the assistance of computers in data analysis.
The author made a case study on Meishin expressway (189, 8km), Tomei expressway (346.4km), and Chuo expressway (123.7km).
Selection of locations or stands for sampling was done regularly in each kilometric post K.P.. Size of sampling area is about 50-100m2, where is a enough area for the sampling plot of grassland and scrub communities. Collection of data, i.e. deciding which data to record, is the important thing, for this is a quick reconnaissance method. For the quick survey, exact location of plot boundaries or measurement of vegetation or site factors was not practiced. Most of the data recorded were based on ocular estimation.
The number of data was 577 plots. The first job in analyzing the data was to punch cards for computer analysis. The dominant species of each ways were calculated, and the relation between the vegetation types of each successional stages and the site factors was analysed.
Then the author discussed the applications and limitations of the reconnaissance method.
This reconnaissance method, however, requires the establishment and sampling of more detailed analytic plots.View full abstractDownload PDF (1515K) -
