　View Summary

For seven species of grasshoppers, air temperature and substrate on which grasshoppers settled, and distance from ground level to the site on which grasshoppers settled were investigated in four grassy spaces with different vegetation coverage, vegetation height and predominant plant species, to clarify environmental factors which affect inhabitation of grasshoppers in grassy space of park. All the seven species of grasshoppers investigated are not monophagous, but oligophagous or polyphagous. Generally, air temperature of site where Atractomorpha late settled seemed to be lowest, followed by Acrida cinerea antennate, and Aiolopus thalassinus tamulus. Gastrimargus marmoratus, Locusta migratoria, and Chorthippus bigutturus maritimus settled on the sites near earth surface, and air temperature near the sites was relatively high. Atractomorpha late and Acrida cinerea antennate inhabited higher places of the grassy place where vegetation coverage was high, and Trilophidia japonica settled only the earth surface of the grassy place where the vegetation coverage was lower. It was suggested that the grasshopper regulates its body temperature by changing stationary position. Therefore the air temperature and the vegetation structure should be important environmental factors of the grasshopper habitats, because they might constrain a certain body temperature and stationary position of the grasshoppers.

　View Summary

We investigated the relations between leaf-air temperature and photosynthetic ratio of cherry trees in order to obtain the fundamental data for applying the biological information to the remote sensing system. Some branches of Prunus jamasakura were cut and put into the water pot prompt once per month from May to October 2001. We measured the surface temperature of ten leaves and photosynthetic ratio every five second for ten minutes every measurement air temperature condition at 20, 25, 30 and 35degreesC with 1000 PAR light intensity. Result as, there was recognized the small significantly relation between leaf temperature and photosynthetic ratio because leaf temperature is usually changed with air temperature. Although, there was recognized large significantly correlations between the difference of the leaf temperature and air temperature and photosynthetic ratio. It is thought that transpiring in healthy plants are active for absorption of water and it cause to drop the leaf temperature. This research showed that the health of cherry trees could be diagnosed for measurement of the difference of leaf and air temperature.

　View Summary

When we do aerial photography and. an environmental research, a remote control helicopter (R/C helicopter) is excellent tool in the next point. For example, the cost of aerial photography and an environmental research work by R/C helicopter are low, also R/C helicopter pilot reservation fee are low price, and free from aviation law in Japan. But, R/C helicopter maneuvering and aerial photographing skills are necessary, and these are difficult to learn. Additionally, if the visibility of R/C helicopter is getting bad when it goes far away, operation is getting difficult. These problems are caused by the badness of autonomous stability on R/C helicopter system.
In this study, we propose a new angle detection sensor for 3 axial rotations which is based on the development of the easy and safe steering system for the operation person.

　View Summary

Environment preservations of the forest become world-widely close-up. The remote sensing technologies by satellite have been used for observation of the forest. However, the observation system on the ground is also needed because the remote sensing by satellite is seriously hindered by atmospheric phenomena and detailed data are necessary for precise analysis of the state of forest. Therefore we developed a multispectral infrared camera system for plant healthiness monitoring. The infrared camera system has five infrared bandpass filters. A hue is defined from the five infrared images. We performed several experiments to confirm that the hue changes according as the plant healthiness decline. In this paper, we propose a plant healthiness evaluation method by detecting hue changes with time. Experimental results of observation of hue changes of a plant through a day using the multispectral infrared camera system are shown. The results show that hue in healthiness parts of plants are more stable than in weak parts when the circumambient conditions such as the sunshine condition are changed.

Establishment of man-made forest management system for energy-use by using Landsat/TM imagery

　View Summary

The Japanese forestry industry has been significantly affected by the increase in low-price timber imports and a diminishing work force. This has had a direct impact on the level of maintenance of the coniferous forests. In this paper, we examine the development of local domestic energy supply schemes in conjunction with effective forest maintenance plans based on data from Landsat/TM imagery. We examined regions in which coniferous forests experienced various levels of blight and to investigated the introduction of energy supply systems using such forests. Both sound and blighted coniferous forests were examined and the characteristics of each area quantified. The supply of energy to a small town using a local blighted coniferous forest was examined. It is estimated that the use of existing wood burning technologies and an effective forest maintenance plan would result in the supply of power to 30% of the households in the town.

Potential for the Restoration of Uncovered Stand Floor Vegetation Caused by the Trampling of Secondary Stands of Quercus serrata in a Suburban Area of Tokyo(PAPERS OF THE 21th SCIENTIFIC RESEARCH MEETING)

　View Summary

In this study, we carried out an experimental restoration of the floor vegetation of the secondary stands of Quercus serrata which became uncovered caused by trampling. The study sites were located in a suburban district of Tokyo, and the experiment was carried out from June to September in 1998. We collected data before the restoration compared them with those obtained at the end of three-month experiment period. The results revealed that the height and the coverage of herb layer did not change significantly. However, the number of recorded species in herb layer increased after the restoration and it showed a correlation with the area of the studied stands and with the calculated stand area available per person living within 250 meters of the examined stands. Furthermore, the number of trampling intolerant species having non-rosette and non-turf forms, considered as characteristic species of the secondary Q. serrata stands, increased after the restoration. This also correlated with the area of Q.serrata stands around the examined stands that existed in 1974. These relations show that not only the area of the present stands but the past landscape in their surroundings should be incorporated as an index when evaluating restoration potential of stand floor vegetation.
