JOURNAL FREE ACCESSThe term Karesansui refers to a dry up garden, e.g. the garden of the Daisen-in and the Ryoanji ternples. However, the term seems to have originally meant exclusively a certain style of stone arrangement in a garden. The Sakuteiki or The Book of Garden, which is attributed to Tachibana Toshituna (1028-1094), and which is the very oldest text mentioning the term, defines Karesansui as a special element of a garden rather than a garden itself. Accodingly, it is generally believed that the Karesansui as described in the Sakuteiki laid the foundation of the establishment of the Karesansui garden in the modern sense, which is today regarded as one of the typical Japanese style gardens.
On the other hand, the origin of the Karesansui has not been clearly explained yet, although several interpretations have appeared.
This paper argues that the origin of the Karesansui as mentioned in the Sakuteiki can be seen in the Chinese garden of the Han period (Western Han 206-8 B.C.; Eastern Han A. D. 25-220), reviewing the Classical Records and considering the archaeological discoveries.View full abstractDownload PDF (13219K) -

JOURNAL FREE ACCESSSeveral laboratory and field experiments were carried out to create attractive wild flower grasslands by sowing and to maintain them by mowing. Hypochoeris radicata L. was used as the material.
The germination rate of the fresh seeds were above 60% at 10-25°C under the light conditions whereas similar percentages were obtained in 10-20°C under dark conditions. The germination rate of seeds stratified at 3°C were above 80% in 10-30°C under the light conditions.The seeds stored below 30°C and under dry conditions, maintained their initial germination ability for at least one year.
More than 60% of the H. radicata L. seeds sown in the out-door pots germinated within 30 days of sowing throughout the year, except in December and January. Sowing from April to June made flowers open and established new seedlings within that year.
Three mowing treatments in a year, in June, August and October, to the H. radicata L. sward at 3cm above ground level brought moderate inhibition of strong growth of the plants and the removal of the dead flower stalks. Due to the mowing treatments, the aesthetic period was able to be prolonged until autumn. Moreover, the H. radicata L. sward will show aesthetic flowering even if it is mowed twice a year, in August and November.View full abstractDownload PDF (3825K) -

JOURNAL FREE ACCESSWe analyzed the characteristics of rural landscape patterns and its effects on ecological process, in the suburbs of the Tsukuba city, Japan, to discuss the conservation method of biotic communities in rural landscapes. The results are summarized as follows 1) rural landscape have been composed of small scale mosaics in time and space, 2) in these mosaics vegetation units interact through species flow, 3) these patterns and interactions form the regeneration complex for plant communities. We may conclude that it is necessary to maintain the diversity of successional stage of vegetation and their spatial network in the landscape structure for the conservation of biotic communities.View full abstractDownload PDF (1902K) -

JOURNAL FREE ACCESSThe sound growth of street trees deeply depends on the soil environment on which they grow.
In order to consider such problems as soil aeration and water permeability of the soil in tree pit, we looked into some physical properties: soil moisture, soil air, and soil compactness. The results of the investigation are as follows:
1. The soil aeration in tree pit is always in poor condition for the sound growth of street trees.
2. The water condition in tree pit is very artificial. There is a remarkable border on soil moisture between the soil dressing and the soil beneath of it.
3. The surface soil in tree pit is stamped down under the foot-steps of pedestrians.
All these matters cause damage to the root system growing in tree pit, and then, they should disturb the sound growth of street trees. So it is necessary to check on the soil environment in tree pit of street trees.View full abstractDownload PDF (858K) -

JOURNAL FREE ACCESSExpo'90 was in Kansai district and Expo'85 was in Kanto. They had similarity in terms of target number of visitors (2, 000, 000), period and scale.
The movement of the visitors in the Expos were analyzed to find their respective characteristics. The conclusion is as follows:
As for common features of both Expos, in such long-run Expos for 6 months, the number of everyday visitors changed each season. In the opening week it was rather less than the average and increased suddenly in leisure seasons, such as the so-called golden week and Japanese ‘bon’ week (special summer holidays), and recorded the highest mark during the closing week.
The number of eveing visitors increased suddenly during the golden week, decreased once, then increased gradually to the highest in the ‘bon’ week, and once again down and up in the closing week.
The rate of the number of visitors on Sunday to the number of a week's visitors was a little over 18% as a whole and the rate of the number of the weekday visitors (excluding saturday) was 12% to 14%.
The rate of the most massed staying visitors to all visitors per day is inversely proportional the rate of eveing visitors to the whole day visitors.
The specific characteristics of Expo'90 are as follows:
It was a horticultural exposition as proven by the fact that it had much more visitors than Expo'85 in the flowery and greenery season, especially during the golden week. There were more eveing or late-huor visitors in Expo'90 which was a typical urban exposition than Expo'85. Expo'90 was an excellent model to enable us to provide for future expositions.
In Expo'90, the 5 seasons divided by the average temperature of a day made it clear that the evening visitors'rate was nearly parallel with the chang of temperature, and the chang of staying visitors in a day was classified to 4 types by the seasons.View full abstractDownload PDF (875K)
