 note = {最近, 環境悪化にともない市街地の樹木の衰退が目立っている。本研究は, この樹木の衰退を早期にしかも的確に判定しうる手法を考究し, さらに大気汚染等環境悪化に敏感に反応し, 指標植物として用いることのできる樹種について検討した。その結果以下のことが認められた。すなわち1)健全な樹木の葉ほど赤外線領域での分光反射率は高い傾向にある。2)環境汚染(二酸化硫黄)濃度とその地点に生育する植物の葉の分光反射率(赤外線領域)との間には, 負の相関関係が認められた。3)葉中の全硫黄量の価が大きいほどその地点の環境汚染(二酸化硫黄)濃度は高い傾向にある。4)葉中のクロロフィル量, C・N量などと環境汚染濃度との関係は一部で認められたが追究を要する。5)カエデ葉, クロマツおよびヒマラヤシーダーの当年生針葉は, 環境悪化に敏感に反応し, 指標植物として適している。特にカエデ葉が, 今回の測定法では, 最も活力を判定しやすい樹種と推定された。, According to the environment deterioration, the vital decay of the tree has been remarkable in the urban area. In this paper, the author researched the early and accurate diagnosis method against this vital decay. Moreover, in order to find a plant indicator which was sensitive to the environment deterioration, such as air pollution, be studied about some tree species. The results are as follows : 1) Healthy tree leaf appeared higher percentage reflectance in the infrared. 2) There was a negative correlation between the concentration of environment pollution (the concentration of sulfur dioxide : SO_2) and the leaf reflectance in the infrared. 3) There was a positive correlation between the concentration of environment pollution (SO_2) and the total sulfur content in the leaf. 4) The concentration of the environment pollution also related to the chlorophyll, carbon, nitrogen in the leaf to some extent. In this point, future study may be necessary. 5) KAEDE (Aceraceae, Acer palmatum THUNB. subsp. palmatum) leaf, KUROMATSU (Pinaceae, Pinoideae, Pinus Thunbergii PARL.) and HIMARAYAN-CEDAR (Pinaceae, Cedrus deodara LOUD.) new needle were sensitive to the environment deterioration, so these were adequate as the plant indicator. Especially, Acer palmatum THUNB. subsp. palmatum leaf showed the most sensitive response by this diagnosis method.},
