本研究では,地球温暖化にともなう冬季の温度上昇がサクラの開花におよぼす影響について明らかにする目的で,サクラの個体を野外の温度条件に常に-1.5℃,0.0℃,+1.5℃,+3.0℃,+4.5℃の温度較差を設定した人工気象室内で育成し,開花等のフェノロジーを調べた.その結果,開花時期は温度の高い区で促進されるものの,開花日の温度条件,花芽の膨らみだしから開花までに必要とする積算温度が上昇することを明らかにした.そして,冬季の温度上昇はサクラの開花に対する温度反応性を鈍らせることを指摘した.

Relationship between shape-archtecture of Miscanthus sacchariflorus community and bio-diversity of the thysanopteran insects on banks in Kyoto City was examined in the summer of 1998 to clarify functional potential of M. sacchariflorus community for habitat of the minute insects and to review direction in the conservation of them. The M. sacchariflorus communities selected for the present study were three types of vegetation showing different shape and scale. The quality of the thrips bio-diversity was estimated based on the species richness, the individuals richness, the pestiferous potential, the food habit, and the wing-form. As a result, for the conservation of the thrips bio-diversity and in the amenities of urban river bank, the more important point in the managenent of the M. sacchariflorus community seemed to be not to enhance the linear and horizontal succession but to keep the vertical extent (3-dimensional archtecture) and the shoot persistence.

MULTISPECTRAL AND HYPERSPECTRAL IMAGE ACQUISITION AND PROCESSING ( SPIE-INT SOC OPTICAL ENGINEERING ) 4548 157 - 160 2001

Environment preservations of the forest become world-widely close-up. The remote sensing technologies have been used for observation of the forest. However, the remote sensing by satellite is seriously hindered by atmospheric phenomena and cannot get the detailed data, which are necessary for precise analysis of the state of forest. So the observation system on the ground is needed. In this paper, we develop a multispectral infrared camera system to investigate the continuous spectra of mid-range infrared whose wavelengths cover around 3000nm to 5000nm. We define hue value in the case that the number of primary image is more than three. An algorithm to calculate the hue value from multispectral infrared images is proposed to obtain spectrum change of plants. An experiment of observation using the multispectral infrared camera system when the plant is growing week from cutting water off is shown.

Landscape Research Japan Online ( The Japanese Institute of Landscape Architecture ) 64 ( 5 ) 595 - 600 2001

In this paper, we researched and investigated the living densities of grasshoppers in the Osaka and Higashi Osaka city along the Kintetsu-Nara railroad line. Twelve experimental circles (r=250m) are settle on the area of each railroad stations. Grasshoppers in the experimental circles are caught by the sweeping method by two persons and they are discriminated and identify the species. The results are follows; 1) Living densities of grasshoppers along the research line increase as an exponential function and if we express this by the regression equation, y = e0.363x-1.699 (y: living density of grasshoppers, x: distance from the Tsuruhashi station). 2) It can be considered that there is no effect of the size and the compositions of the open space for the living densities of grasshoppers.

本研究では,地球温暖化が樹木のフェノロジーに及ぼす影響を明らかにするため,気象庁の観測によるソメイヨシノの開花日について近年の温暖化データを加えたうえで緯度別に再整理した.その結果,冬季の温度上昇がおこると,北方では開花が早くなるが,南方では開花が遅れることが再確認された.逆に厳冬の場合では南方で開花が早まることも明らかとなった.さらに,花芽形成から開花までの低温日の日数が多くなるほど開花日の日平均気温が低下する傾向を認め,地球温暖化が進行した場合,南方では休眠解除を促進する低温が不足し,開花が遅れる可能性を指摘した.

Landscape Research Japan Online ( The Japanese Institute of Landscape Architecture ) 63 ( 5 ) 447 - 450 2000

The purposes of this study are to obtain a preliminary knowledge for the re-forestry of slope areas with endemic plants stored in a forest soils. The examination area was built on the road side slope in Kagawa pref.. The altitude is about 200m, the direction of the slope surface is S34°W and the average gradient is 34°. On 16-18, March and 17-18, June 1997, the experimental soil was picked at three different points, first at a ridge area of the mountain, second at a middle area and third at a dale area of the same mountain and packed them in the jute sandbags. After two years the examination area is covered with many plants. The plants density are 4.4-13.1 stems/sqm and 15-26 spaces are confirmed in the one separated area. The predominant plants in this area are Mallotus japonicus, Rhus javanica, Araria elata and other pioneer plants. In the area of ridge soil packing sandbags, a lot of Miscanthus sinensis spring up and hang over the other plants. The well covered areas by these plants are protected from soil erosion. The relation between the erosion ratio(%):(y) and the sum up plants coverage ratio(%):(x) is calculated and the regression equation is y = -0.11x + 33.3 (r=-0.521^*).

Function of 'Ecological Tree Planting' Site in Artificial Islands on the Fifteenth Year After Planting as Habitats of Insects, with Special Reference to Stand Structure Utilized by a Cicada Species, Cryptotympana facialis(PAPERS OF THE 18th SCIENTIFIC RESEARCH MEETING)

NAKASHIMA Atsushi, NAKAO Shiro, YABU Shinobu, YAMADA Hiroyuki

Landscape Research Japan Online ( The Japanese Institute of Landscape Architecture ) 63 ( 5 ) 509 - 514 2000

To cralify the formation of the structure of forest stands created by 'ecological tree planting' techniqe in artificial islands and its potential for habitats of insects, the conditions of the stands and the insect fauna were investigated in an artificial island (on the fifteenth year after planting) and neighboring areas at Gobo city. In the island, the numbers of species and individuals of ground beetles such as silphid and carabid beetles were few, however, a large number of cicadas, particularly Cryptotympana facialis, were inhabiting in the island. The adult cicadas abounded in the stands showing well developed vegetation layers, and the upper layer were mainly composed of Machilus thunbergu and Elaecocarpus sylvestris. But most of the cicadas seemed to oviposit and/or moult into adults in the stands without such upper layer. In general, stands composed of Quercus phillyraeoides and Rhaphiolepis indica were utilized as oviposition and/or emergence place.

The impacts of the long-distance transportation of plant materials for the revegetation on local populations of insects.

NAKAO Shiro, YABU Shinobu, NAKASHIMA Astushi

ENVIRONMENTAL SYSTEMS RESEARCH ( Japan Society of Civil Engineers ) 25 665 - 669 1997

These days, plant materials for the revegetation have been transported over the long distance in Japan. Because the plant materials have been carried with large quantities of soil and other plants, they must have been accompanied by many living things, including a wide range of insects. In this paper, we demonstrated that the evidence of the genetic divergence among five local populations of the small insect, Thrips nigropilosus, living on the one of the plant materials for the revegetation, Artemisia princeps; critical daylengths at 18°C for induction of the reproductive diapause and the brachypterous form in females of four populations, Wakkanai, Abashiri, Kyoto and Nagasaki populations, were between 11hrs and 14hrs and different from each other, whereas Naha population dose not show critical daylengths between 8hrs and 15hrs. Inter-population crosses between the local populations probably disturbe their genetic constructions. This possibly results in a decrease in the number of individuals in the population, because the diapause and the wing form are life history traits directly affecting the reproductive success. Thus, the transportation of the plant materials may disturbe genetic construction of local populations of living things. A general rule for the use of plant materials for the revegetation should be proposed.
