首都圏におけるスギ・ヒノキ科花粉の飛散と気象との関係について(2) Correlation of Airborne Pollen Counts of Cryptomeria Japonica and Cupressaceae with Meteorological Conditions in the Metropolitan Area of Japan(2) 高山, 晴光 タカヤマ, ハルミツ 中村, 圭三 ナカムラ, ケイゾウ 勇, 勝美 イサミ, カツミ Takayama, Harumitsu Nakamura, Keizo Isami, Katsumi In order make clear the relation between airborne pollen counts of Cryptomeria Japonica and Cupressaceae and meteorological conditions in the Metropolitan area, the Airborne pollen is surveyed at three pollen count stations (Suginami, Satte and Akiruno) from February to April 1997. The results are summarized as follows : 1) In Suginami and Satte, the dates of beginning of dispersion were February 8 and February 16 respectively. In Suginami, Satte and Akiruno, the maximum pollen counts were taken on April 8 (265/cm^2), March 7 (182/cm^2) and April 9 (1036/cm^2) respectively. And in those stations the total pollen counts were 1933/cm^2 (Suginami), 1862/cm^2 (Satte) and 10752/cm^2 (Akiruno) during the period of February 28-April 30 respectively. 2) The peaks of the pollen counts on the daily variation of these agree with the peaks of the daily maximum temperature at all three stations March 7 and April 8-9,3) The coefficient of correlation between the pollen counts and the daily maximum temperature show the high values in the period of increasing pollen dispersion in three stations (Suginami : 0.75,, Satte : 0.56,Akiruno : 0.79). But the coefficients show the low values after the period in three stations. 4) The main origin of pollen in Suginami and Akiruno is probably an artificial forest of Cryptomeria Japonica and Cupressaceae in the western Kantou, and that in Satte is probably an artificial forest of Cryptomeria Japonica and Cupressaceae in the northern Kantou, judging from wind direction and pollen counts. 5) These results suggest the airborne pollen counts are not affected only by the meteorological conditions, but also by the biological conditions of the plants. 1998-04-30 jpn departmental bulletin paper https://keiai.repo.nii.ac.jp/records/1605 AN1041551X 環境情報研究 Journal of Environmental Studies 6 53 63 https://keiai.repo.nii.ac.jp/record/1605/files/KJ00000195388.pdf application/pdf 676.5 kB 2016-08-18
