JOURNAL FREE ACCESSThis study attempts to consider the planting distribution of evergreen broad-leaved trees and climatic factors affecting their zonal arrangements in northeastern part of Japan located mainly on the cool-temperate decidous forest zone. Data on 41 tree species and 64 cities were analized.
The results obtained from this study are as follows; 1) Planting distribution depends mainly on thermal factors, in particular on winter coldness, which can be explained by the results of factor analysis and Spearman's rank-order correlation analysis. 2) Each city and tree can be classified into 5 groups by using Coldness Index obtained from the results of rearrangement of the planting situation table drawn though the analysis of Quantification Theory III and cluster analysis. 3) Potential zoning map for landscape planting of evergreen broad-leaved trees was drawn based on the Coldness Index. 4) Planting distribution of each species can almost explained by thermal factors, but remainder can explained by managements obtained from the results of multiple regression. 5) Rate of tree which bear nuts can make clear the planting distribution of Quercus myrsinaefolia and this method can apply to explain the northern limit of other species.View full abstractDownload PDF (1678K) -

JOURNAL FREE ACCESSIn order to establish the practice of wildflowering site formation by native herbs in suburban secondary forest, floor vegetation of management Pinus densiflora forests were surveied in National Musashi Hill Forest Park, Saitama Prefecture, and floor vegetation of Quercus serrata forests were experimentally cut in Miki City, Hyogo Prefecture. Management guide extracted from the results, were as follows.View full abstractDownload PDF (5862K) -

JOURNAL FREE ACCESSThe composition of building units and open spaces on a residential lot represents a characteristic feature of space structure built in the historic urban area. The case study at five areas in Kinki district provides the following understandings in spatial meaning of the“niwa”(yard or garden) space.
(1) A space composition unit of the buildings and the niwa is recognized most typically in the form that a main buildig, annexes, and utiliy units are arranged with strong orientation toward the niwa space which provides adequate environmental conditions.
The increase of lot size, especially that of lot depth promotes the possibility that the secondary unit of the space composition is organized in the rear part of the lot.
(2) The functional analysis in conjunction with the building floor plan identifys spatial meanings of the niwa space summarized as ; the space which absorb spatial hiearchy from community to prvacy attached to the floor plan of the main building, the space which is a uniting medium between the main building and the annexes, and the space which separates the main building and the annex by enhancing functional unity of the front and the rear section of the site plan respectively.
(3) Number of the niwa space unit is closly related to the building density represented by building area and the building-to-lot area ratio (BLR). The marginal density in which a single unit of the niwa space will be retained is unusually high and 80 percent of the BLR or 30 spuare meter of the open space.
(4) The mass composition of the building units which guarantees acceptable environmental condition of the niwa space is demonstrated in the arrangement pattern of the building volume allocated in each spatial zone of the lot depth.View full abstractDownload PDF (2507K) -

JOURNAL FREE ACCESSFrom the viewpoint of restoring the native landscape, stem cuttings obtained from coppice seems to be suitable for revegetation of steep slopes which is formed when we develop newtowns or roads in hilly areas. In the previous article, we stated that Quercus lauca showed a considerable rooting by the treatment with β3-Indolebutyric Acid (IBA) 2000 ppm solution, even with 16-18 cm stem girth. The additional experimental research was conducted with sixteen species under different conditions, in 1985 and 1986.
The results were as follows: Most of species sprouted shoots by summer, except Castanopsis cuspidata, Ternstroemia gymnanthera, Rhododendron reticulatum and Eurya japonica. Whereas Quercus glauca showed enough rooting in early spring settings, in the case of autumn setting, almost all died. Since the other species also died in autumn settings, autumn setting was judged to be unsuitable way for stem cuttings.
In addition to Quercus glauca, such evergreen trees as Camellia japonica and Ilex crenata developed enough roots by the treatment with IBA 2000 ppm solution. However, deciduous trees such as Clethra barbinervis, Quercus serrata, Quercus variabilis, Lyonia ovalifolia and Prunus jamasakura mostly died by late summer even in the case of autumn cuttings. The results suggest that these deciduous trees lack abilities to develop enough roots by summer.
Incidentally, shading or daily watering caused serious damage due to spread of harmful bacilli or fungi, and no shade and weekly watering brought rather better results.View full abstractDownload PDF (9185K) -
