摘要
本文从我国红壤的特性和我国酸雨的特点出发论述了华南红壤对酸雨敏感性的特点。提出了研究红壤对酸雨敏感性的酸缓冲曲线法。根据土壤的酸缓冲曲线提出了两个具体指标:(1)土壤的酸害容量;(2)土壤的酸敏感值(△pH_(敏感值))。根据大量酸缓冲曲线的结果,对指标分别进行了初步分级,并对广东、广西、海南三省的土壤进行了概略分区。
On the basis of the properties of red soils and the features of
acid rain thecharacteristics of sensitivity of red soils to acid rain in South China are dealt inthe
present article. An acid-buffer curve method is put forward for studying thesensitivity of red
soils to acid rain. In terms of soil acid-buffer curves two indices,i.e.soil acid-damage capacity
and soil acid-sensitivity value(△pH.v.),are propo-sed.Accotding to a lot of results of acid-buffer
curves the primary classes of bothindices and the reconnaissance division map of soil
acid-sensitivity in Guangdong,Guangxi and Hainan have been made.
