项目摘要

The purpose of this research is to develop the quantitative monitoring technique in order to protect the rare insects which inhabit the central mountain area in Nagano Prefecture. Another purpose lies in developing the technique of the environmental evaluation for the preservation of biodiversity and continuous use of the mountain resources for the mountaineering and the sightseeing.Quantitative investigations using the methods of the route census, the fixed point investigation and so on were carried out on the butterfly community in the Southern Alps and the mountainous areas of the Ina valley for 2003-2004. And also the microhabitat of larvae and pupae of Himalopsyche japonica was investigated in mountain streams. A total of 203 and 246 individuals belonging to 16 and 11 species of butterflies at sub-alpine zone and alpine zone in Mt. Senjo were observed in the year 2003, respectively. And also a total of 570 and 336 individuals belonging to 36 and 29 species of butterflies at forestry road and the source area of Mibu River were observed.There was a correlation during the altitude and species diversity of the butterfly community. A significant positive correlation was admitted among the flowering index of the alpine plant, and the abundance or the number of species of butterflies. It was examined whether the route census and the fixed point observation were effective as a method of the monitoring of the rare species based on these data. The possibility of the monitoring technique using GIS was examined. The investigation of genetic diversity in the populations of alpine butterflies was tried.

本研究的目的是发展定量监测技术，以保护长野县中部山区的珍稀昆虫。2003-2004年，采用路线普查、定点调查等方法，对南阿尔卑斯山和伊纳河谷山区的蝴蝶群落进行了定量调查。并对日本喜马偕尔人幼虫和蛹的微生境进行了调查。分别记录了亚高山带和高山带蝶类16种和11种，共计203只和246只。在2003年，分别观察了Senjo。在森林公路和米埠河源头分别观察到蝴蝶36种570只和336只，表明海拔高度与蝴蝶群落的物种多样性存在相关性。高山植物的开花指数与蝴蝶的丰度或种类数呈显著正相关。根据这些数据，研究了路线普查和定点观察作为监测稀有物种的方法是否有效。利用地理信息系统的监测技术的可能性进行了审查。对高山蝶种群的遗传多样性进行了初步研究。
