訂正日: 2009/08/07 訂正理由: - 訂正箇所: 論文抄録 訂正内容: Wrong : The relationship between ground temperature and presence of snow cover detected by an ultrasonic snow depth meter was evaluated to clarify temperature characteristics on snowcovered ground surfaces. The temperature on the ground during periods of snow cover was 0.5±1.0°C(mean±s.d., -0.4°C3.2°C). Under these conditions, when the temperature on the ground was lower than 3.2°C and its standard deviation in about 10 hours was lower than±0.22°C, 95% of the recorded locations were under snow cover. Using these conditions, the duration of snow cover in 19 representative forests in Toyama prefecture, central Japan, was estimated. The estimated duration of snow cover on the forest floor was 22.5 days per year in warm-temperate evergreen-deciduous broadleaved(Machilus thunbergii-Celtis sinensis) forest, 58.4104.5 days per year in warm-temperate deciduous broadleaved(e.g. Quercus serrata)forest, 113.3158.6 days per year in temperate deciduous broadleaved(e.g. Fagus crenata)forest, 150.3158.7 days per year in temperate coniferous-deciduous broadleaved(Cryptomeria japonica-F. crenata)forest, 167.0 days per year in temperate-subalpine transitional forest, 214.5 days per year in subalpine(Abies mariesii)forest, and 200.4207.1 days per year in the sub alpine(Pinus pumila)forest. The relationship between altitude and the duration of forest floor snow cover was fitted well with a quadratic curve.
