ジャーナル フリー本報は居住地における緑地の機能別満足度の構造と満足度を規定する諸条件を明らかにすることを目的としている。
調査は昭和49年に札幌市において行なわれたもので, 結果の概略は次の如くである。
(1)緑地の機能別満足度の相関マトリックスに基づく主成分分析の結果, 第1主成分は緑地の一般的評価性を示すものと考えられ, 分散寄与率も大きく, データ集約上重要である。
(2)主因子分析-バリマックス回転により 「利用性」 「快適性」 「環境保全性」 を表わすと考えられる共通評価因子が見出された。
(3)これらの因子のうち, 緑地の全体的満足度には 「快適性」 が最も大きな効果を示した。
(4)各緑地満足度を規定する要因として, 全体的には, 樹木地率, 草地率, 人口密度などが重要であり, 「利用性」 因子では公園充足度 (児童公園以外), 「快適性」 囚子では樹木地, 「環境保全性」 因子では土地利用や人口密度などによる影響が大きいなどの諸特性がみられた。
(5)以上の結果から緑地評価を, 個別機能評価,全体的評価, 一般性評価, 3つの共通因子による評価およびそれらの総合化による評価などに区分して考えることが出来る。抄録全体を表示PDF形式でダウンロード (1232K) -

ジャーナル フリーIt 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.抄録全体を表示PDF形式でダウンロード (7804K) -

ジャーナル フリーSlope 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.抄録全体を表示PDF形式でダウンロード (1515K) -
