山上憶良が詠んだことにはじまる秋を代表する野草である秋の七草は,その姿の美しさや風情を楽しむことで,古くから様々な人々に親しまれてきた。今回,日本最古の歌集である万葉集の中で秋の七草が詠み込まれた歌から,万葉集が編纂された時代の秋の七草の主な生育立地を把握し,「野」「山・岡」「庭」「街・里」に分類した。その結果,七草全体では「野」が最も多く,植物種によって差があるものの,身近に野草を置こうとする歌人の意向から庭に植えたと考えられる植物種も多数見られた。特にナデシコは栽培されたものを詠んだ歌が多く,ハギは様々な立地に幅広く生育するものが詠まれていた。

The leaves of Oshima cherry (Prunus Wilson var. speciosa Makino) are edible and used to wrap sakuramochi. Seventy percent of leaves of the Oshima cherry are produced in Matsuzaki town, Izu Peninsula. In this town, cherry trees are cultivated for harvesting their leaves. These trees are closely planted and pruned, enabling them to grow many tillers, which spread out and form the distinctive landscape in this area. In this study, we investigated the actual distribution, forming process of leaves in cherry tree fields, and change in the production process in Matsuzaki town. From the results, we assumed that the number of cherry trees planted corresponded to the amount of charcoal produced. However, the field cultivation method of cherry trees was devised only by the end of the 1960s, after the production of charcoal decreased due to an energy revolution, which resulted in a crisis in the cherry tree leaf production. It was considered that cherry tree fields were distributed throughout Matsuzaki town. However, our results show that these fields are unevenly distributed.

近年,農村ではコンクリート製品の影響に加え,圃場整備等の土地造成により土壌 pH がアルカリ性に傾き,在来植物が発芽不良や生育不良を起こしている可能性がある。本研究では,pH が在来植物,特に草原性の野草類の発芽に及ぼす影響を明らかにした。結果,対象 16種のうち,7種は有意差が認められ,草原性野草類の中には,pH が発芽に影響を及ぼし,アルカリ性が強いと発芽を抑制・もしくは遅らせる種があることがわかった。特に,オトコエシ・オミナエシ・ワレモコウ・カワラナデシコの 4種は,強アルカリ性の条件下での発芽率が低く,在来野草類からなる良質な半自然草地の保全・復元には,土壌 pH が重要な要素であると考えられた。

万葉集及び勅撰和歌集において松が詠まれた歌からその生育立地の推定を行い,年代毎の変遷を明らかにした。計 22集の和歌集には 1,493歌で松が詠まれており,内 1,147歌(77 %) で生育立地の特定が可能であった。生育立地は臨海部が 22~35 %と変動しつつも概ね一定の割合を占めており,中でも海浜のクロマツ林を詠んだものが多かった。本格的な海浜域での造林が始まる以前より,クロマツ林が広く存在し,その植生景観に価値が置かれてきたことが示された。内陸部は年代が下るにつれて割合が増加し,1200年代以降は浜以上の割合で山の松が詠まれるようになった。これは山に関連する用語の種類の多様化,「名もなき山」や「聴覚としての山の松」の嗜好の広がりによるものと考えられた。

It can be said graft is important technique from a viewpoint of landscape from some their feature. However, their techniques have developed in pomological field. In this study, we examined about the historical transition of graft use through literature. In addition, we considered about position of graft at the industry of tree production in recent years and transmitting of graft techniques through a listening to people who have graft techniques and nursery stock producers. As a result, graft has already been done for ornamental trees at Heian era. It was thought that graft techniques were actively used in the background of the gardening cultural prosperity at Azuchi-Momoyama and Edo era. Afterwards, object of graft shifted to the fruit tree since Meiji era. About the transmitting of graft techniques, there were a lot of cases with transmission to the relative. There is a tendency to transmit movements of graft only when it is not relative. Intention of graft is the overall techniques include that caring and environmental making at the before and after graft. Depression of plant industry, difficulty that compete in plant industry and weakening of the consciousness that taking over the family business caused a decreases in the number of workman of the next generation.

資料の少ない古代~中世の緑化文化を検討するため,主な和歌集に詠まれている植物および植物に対する行為を分析した。その結果,万葉集および第1~8集の勅撰和歌集の中で植物は計4,171首,植物に対する行為は計1,449首詠まれていた。時代区分毎にそれぞれ割合を求めたところ,奈良時代から平安時代にかけて,詠まれた植物の嗜好がハギからサクラに転換していた。緑化に関わる行為としては,植栽として「植える」「蒔く」「刺す (挿し木) 」,植生管理として「刈る」「伐る」「抜く」「焚く・焼く」「切る」が認められた。また,奈良時代には植物との多様な関わりが存在していたが,それ以降の時代では植栽という行為に対して意識が薄れていったことが示された。

People have made various relations between plants for every time or area. As a result, the vegetation and the local scene have been formed for every area. But, it is apprehensive about increase of a rural management abandonment place, and the fall of the biodiversity accompanying it in recent years. There is a Japanese lacquer producer who continues four generation in southern Yamizo Mountains. This study aimed to elucidate roles of the traditional plant resource utilization for conserving an indigenous rural landscape element, particularly semi-natural grasslands. We clarified the spatial distributions of woodlots for the lacquer tapping, habitat properties, management state and understory vegetation for this Japanese lacquer produce at an example. As a result, It was shifting to the landscape of large-scale woodlots for the lacquer tapping on a abandoned cultivated land from small-scale woodlots on the base of a mountain or a bank. However, the kind of many species of Miscanthetum sinensis-class is a growth cage as a good half-natural grassland in the habitat of a bank. That is, the difference had arisen in the composition of woodlots floor vegetation by the career of the land. And It was considered that those species richness decreasing when management abandonment progressed.

As far as the work continues, the waterside space where traditional fish catching is carried on possesses the value as the cultural landscape. We aimed at the fish weirs by this research. We considered the contemporary significance and factors in the continuation by investigate the placing on the system, change in the material, the material amount necessary to set up, the situation of technological succession and consciousness of establishment people in Nakagawa River. As a result, we guess that fish weirs possessed several current significances. The first is the significance that fish weirs are continued, changing from the traditional material and form. The second is the fact that there is a fish weir which stuck to the traditional material and form. We regard that diversity of continuation of fish weirs to existence of the form of several kinds of fish weir. In the third, the significances that material of woods and bamboos are being used much. And those materials were obtained from forests in surrounding areas. And we suggest that the spirit and the fulfillment to build fish weirs are important factors in the continuation.
