摘要
探讨了各种人为因素,如施用化学肥料、酸沉降、酸性矿坑水排放、土地利用以及植物体被移去、皆伐、全树利用等诱导下的红壤酸化机制。通过比较分析,导致酸化发生的两个基本过程:一是增加H+,二是减少盐基;任何有利于这两个过程进行的人为因素都将导致或加重土壤酸化。对各种酸化提出了相应的防治对策。
Different mechanisms of red soil acidification induced by man-made factors, such as chemical fertilizer, acid rain, acidic mine drainage, utilization model of soil, massive plant biomass moved from the soil, are discussed inthe present paper. By comparison and evaluation, it has been discovered that two basic processes of acidification for soils under the influence of man-made factors consist of increasing H+ and decreasing base. In addition, several methodologies and strategy in controlling acidification of red soils are proposed.
