采用分析和实验相结合的方法，研究了7种森林树种对土壤酸化速率的影响。用常规的分析方法对土壤进行了调查，并在种植了几个树种的20个酸性场地进行了两次实验。测试矿物和阳离子交换树脂被插入土层(凋落物；A层和B层)，然后在不同的时期保持。参照Robert等人提出的酸解和酸络合分解理论解释了这些实验的结果。罗伯特，M.，Razzaghe，M.，Vicente，M.A.，Venau，G.，1979。复盖层上的生物嵌合体与L的硅酸盐蚀变作用有关。SCI。索尔2(3)、153-174。]。主要结论如下：(I)母质性质对试验矿物的风化影响很大；(Ii)酸化和风化尤其发生在休眠期；(Iii)与相同条件下测试的其他树种相比，挪威云杉(Picea Abies Karsten)促进了土壤的酸化和试验矿物的风化；(Iv)在本研究中，树种对试验矿物的影响相对较小。(C)1998年爱思唯尔科学公司。
Seven forest tree species were tested for their impact on the rate of soil acidification, using both analytical and experimental methods. Soils were investigated by usual analytical methods, and two experiments were carried out on 20 acidic sites where several tree species had been planted. Test-minerals and cation-exchange resins were inserted into soil layers (litter; A and B horizons) and then maintained over various periods. The results of these experiments were interpreted with reference to the theory of acidolysis and acidocomplexolysis developed by Robert et al. [Robert, M., Razzaghe, M., Vicente, M.A., Veneau, G., 1979. R (o) over cap le du facteur biochimique dans l'alteration des mineraux silicates. Sci. Sol. 2 (3), 153-174.]. The main conclusions were as follows: (i) The nature of the parent material strongly influenced the weathering of the test-mineral; (ii) Acidification and weathering took place particularly during the dormant period; (iii) Norway spruce (Picea abies Karsten) enhanced the acidification of soils and weathering of test-minerals in comparison with the other tree species tested under the same conditions; (iv) In this study, the effects of tree species were minor in comparison to the other factors.
