The results show: the most sensitive Chinese area to acid deposition is Podzolic soil area, then follow Latosol, Dark brown forest soil and Black soil areas; Ferraisol and Yellow-brown earth area in southern China can buffer about 0.8-1. 6 g Sm〓yr〓 sulfur deposition; the least sensitive areas to acid deposition are mainly Xerosol area in northwest China, Alpine soil area in the Qingzang Plateau, and Dark loessial soil and Chernozem areas; the main reason for lower critical load in northeastern areas and higher critical load in Ferralsol and Yellow-brown earth areas in China can be attributed to the obvious difference in temperature, humidity and soil properties.

研究表明：我国土壤对酸沉降最敏感的区域是漂灰土带，其次是砖红壤土区、暗棕壤带和黑土区，南部富铝土区域大致可接受O.8-1.6 g Sm〓yr〓的硫沉降，对酸沉降最不敏感的区域主要集中在西北干旱土和青藏高原的高山土区域以及黑垆土和黑钙土带；导致我国东北地区酸沉降临界负荷偏低和富铝土区域酸沉降临界负荷偏高的重要原因，是这些地区的气温、湿度和土壤质地存在显著差异。
