Screening of forest decline risk  –  South Kanto CL ( acidity ) : 臨界負荷量 ( molc ha -1  yr -1 ,以下同), BC we : 土壌鉱物の化学的風化による塩基生成量( Na,K,Mg,Ca ) , Bc gu : 植物による正味の塩基吸収量( K,Mg,Ca)  , N gu : 植物による正味の窒素吸収量, N im : 安定な有機物としての窒素不動化量, ,[object Object],[object Object],[object Object],[object Object],N de : 脱窒量, Al le ( ml ) :  負荷が閾値にある際の単核無機 Al イオン浸出量,  H le ( ml ) : 同様に水素イオン浸出量, HCO 3le ( ml ) : 同様に炭酸水素イオン浸出量, RCOO le ( ml ) : 同様に有機酸イオン浸出量.
Screening of forest decline risk  –  South Kanto ,[object Object],BC/A l比は,日本の樹種(針葉樹:アカマツ,広葉樹:ブナ)を用いた実験より得られた値(伊豆田  2002 )を適用.
Screening of forest decline risk  –  South Kanto ,[object Object],BC/A l比は,ドイツトウヒを用いた実験より得られた値( Sverdrup and Warfvinge 1993 ;欧州で一般に持ちられる値)を適用.
Screening of forest decline risk  –  South Kanto ,[object Object],超過負荷  =  酸性沈着量  -  臨界負荷量 超過負荷は,それが長期的に継続した場合に影響が顕在化する可能性があることを意味し,現状あるいは近い将来の森林衰退と必ずしも対応しない.
