| Abstract |
国内各地の水文試験地において森林の水・物質循環を調べる研究が行われているが，それらの結果を相互に比較するためには，各試験地の気象特性が明らかとなっていることが必要な条件となる．本研究では，水・物質循環研究が行われている福岡演習林の御手洗水試験流域における気象特性を調べた．本試験地における2003年から2006年までの年平均の降水量は2003 mm，気温は16.2 ℃，相対湿度は69％，日全天日射量...は12.6 MJ m^(-2)，風速は1.2 m s^(-1)であった．年降水量と平均気温のみに着目すれば，本試験地に近い試験地として，江田島，愛知，鹿北，郡山の各試験地が同定された．また，本試験地の気象データを近隣気象官署（福岡・飯塚）のデータと比較したところ，本試験地のデータは福岡より飯塚に近く，データ補完などの際には福岡よりも飯塚のデータを用いるほうが好ましいことが明らかになった．
Some studies have been examining water and nutrient cycles in various forested watersheds in Japan. For comparing results with these studies, meteorological characteristics of each watershed should be clarified. We examined meteorological characteristics of Ochozu Experimental Watershed in Kasuya research forest, Kyushu University for the four years 2003 to 2006. Annual precipitation, annual mean air temperature, relative humidity, solar radiation, and wind speed were 2003 mm, 16.2 ℃, 69％, 12.6 MJ m^(-2), and 1.2 m s^(-1), respectively. Annual precipitation and annual mean air temperature of the Ochozu experimental watershed were almost the same as those of Etajima, Aichi, Kahoku, and Koriyama watersheds. By comparing the precipitation and air temperature of Ochozu with those at Fukuoka and Iizuka Meteorological Observations, we found that the precipitation and air temperature of Ochozu were more highly related to those of Iizuka, rather than of Fukuoka. Thus, the use of the data from Iizuka rather than from Fukuoka is recommended for filling gaps in precipitation and air temperature records taken at Ochozu.show more
