    トカラ語B«Udānālaṅkāra»に於けるAvadāna利用について(2)

    No full text
    西域北道一帯で流布した説一切有部の文献である《Udānavarga》に対する注釈として、トカラ語B仏典には《Udānālaṅkāra》と呼ばれる文献が存在している。この注釈の作者はDharmasomaであるという事がトカラ語本文中に記されているが、現在まで梵文学中にこの人物及びこの人物に帰せられる他の作品は知られていない。本稿ではこのトカラ語Bによる注釈の第十章第二韻文に対する因縁諦として、梵文《Kalpanāmaṇḍitikā》第四十八章に相当する物語の引用が見られるだけでなく、尚且つこの物語が同じく《Udānavarga》に対する漢訳の注釈である『出曜経』では第十章第八韻文の因縁諦として利用されている点を指摘するとともに、これらの事実は、トカラ仏教において《Udānālaṅkāra》が編纂される過程で、本来特定の韻文と結びつけられていた因縁諦が別の物語に置き換えられた可能性を示し、トカラ語《Udānālaṅkāra》の全体に対応する梵文の原典は存在しなかったとする筆者の説を支持する傍証となる事を論じる。Among the Tocharian B Buddhist texts, there is a literary work entitled the Udānālaṅkāra, a commentary on the Udānavarga in Sanskrit. According to this text, the author is called Dharmasoma, although neither his work nor his name has been known to the Buddhist Sanskrit literature yet. This text reveals that the Udānavarga in Sanskrit had prevailed in Tocharian Buddhism. However, the Udānālaṅkāra has not yet received the attention that it deserves. In this paper, I will discuss the textual material used in the Uddna-lankara in Tocharian B. According to my research, the Avadana text which is given as the 48th text in the Kalpanāmaṇḍitikā in Sanskrit is quoted here as the narrative attached to Udv. X 2. However, it is worthy of notice that the same text is used as the narrative attached to Udv. X 8 in the Chinese commentary on the Udanavarga. This fact could show that the original tale connected to this verse would have been replaced by this Avadana text in the course of the compilation of the Udānālaṅkāra in Tocharian, and could also confirm my hypothesis proposed in Ogihara (2011a) that no original Sanskrit text existed that corresponds to the whole text of the Udānālaṅkāra in Tocharian.論文 Article

    Most parts of Japan are covered with forests that play multifunctional role in environmental conservation. Forest connectivity in the Japanese islands was evaluated by calculating a newly proposed index "CON" defined as the number of the neighboring forest grid cells in 3×3 grid cells, using a standard grid (approx, 1km grid cell) database of vegetation developed by the Japan Envionment Agency. The results of our study indicated that the forests in Chugoku districrt are comparatively fragmented for its forest coverage ratio, and forest connectivity strongly correlated to topographical factors

    The purpose of this study is to clarify the relationship between the distribution of small-scale green spaces and the butterfly assemblages in urbanizing area located at the north-east of Ichikawa city. As an indices of ecological gradient by the distribution of urban green covers (over 2m2), GCI (Green Cluster Index) of each vegetation type, co-occurrence of the different vegetation types, distance from each vegetation type, and diversity index of vegetation were calculated by using high-resolution aerial photograph image. As a result of analysis on the relationship between butterfly assemblages in each survey root units and the indices around them, using Classification and Regression Trees, it was clarified that distribution of deciduous trees in large scale area and small-scale mosaics of vegetations in its surrounding area are important factors for the width of butterfly assemblages

    In this study, we investigated the most suitable extensive cultivation management cycle for conserving floral diversity in a fallow paddy field. The following three studies were made for this purpose: (1) review of the examples of paddy restoration (2) vegetation survey of fallow paddy fields and (3)rhizome study of Phragmites australis. The paddy restoration works involve those aboveground and underground i.e. mowing and plowing. The following two types of plants were found to interfere with mowing: tall-stem plants (e.g. Phragmites australis and Miscanthus sacchariflorus) and rhizome and erect-stem plants (e.g. Isachne globosa and Leersia sayanuka). These plants increased greatly during the second year in fallow. In plowing, plants with strong and long rhizome (e.g. P. australis and M. sacchariflorus) were found to interfere. The weight of their rhizome increased greatly during the forth year in fallow. Plowing is four-times laborious compared to mowing in restoration work. Therefore it is suggested that cultivation of once every four years is effective in restoration from the labor point of view

    Recently, municipal ordinances regarding Satochi landscapes conservation have been frequently enacted, and expectations for these ordinances have been increasing. Improvement of the implementation of these municipal ordinances can be regarded as urgent and important. As a first step toward improvement, this paper attempts to give a detailed picture of these ordinances at regional scale by classification based on the contents of the documents of in these ordinances. As a result, three different types were distinguished. The first type consisted of ordinances enacted recently, in which a target site with farmland and forest and the community participation system as implementation measure were described (Type A). It was considered that this type of ordinance responded to the problems on conserving farmland and forest integrally. The second type consisted of ordinances in which government-initiated implementation measures regarding the maintenance of forests or agricultural lands were described (Type B). The third type consisted of ordinances without a definite description of the target site and implementation measures (Type C). It was also suggested that ordinances of Type A and Type B had different institutional issues. It was considered that Type A and Type B contributed to different aspect of Satochi landscape conservation and that a resolution of issues of each type was needed

    In der Bundesrepublik Deutschland findet alle zwei Jahre der Bundeswettbewerb "Unser Dorf soll schoener werden" statt. Er hat zum Ziel, die Teilnahme der Buerger am Prozess der Dorferneuerung und der Dorfverschoenerung im aesthetischen wie im oekologischen Sinne zu foerdern. Der Autor war eingeladen, als Gast der Bundespruefungskommission das Bewertungsverfahren beim 14. Bundeswettbewerb im Jahre 1987 kennenzulernen. Die Ergebnisse der Bewertung wurden nach der Faktorenanalyse untersucht, wobei insbesondere zwei Bewertungskriterien sowohl die allgemeine wie die differenzierende Bedeutung der Gesamtbewertung erklaeren. Die Bewertung der Gruenordnung einschliesslich der Anlage von Biotopen ist das signifikanteste Element des Faktors I. Dies bedeutet, dass die Gruenordnung das entscheidende Element in der Gesamtbewertung darstellt. Der Faktor II wird im Gegensatz dazu aus der staedtebaulich/denkmalpflegerischen Gestaltung sowie der Buergerbeteiligung gebildet. Dies sind Elemente, die im Entscheidungsprozess unabhaengig voneinander bewertet werden. Zusammenfassend laesst sich sagen, dass in der derzeitigen Bewertung die Erhaltung oder Schaffung laendlicher Oekosysteme gegenueber seinen Verschoenerungsmassnahmen deutlich bevorzugt wird
