Soil pH was in significant negative correlation with exchangeable acid and nonexchangeable acid, but in significant positive correlation with base saturation, which is mainly restrained by dominant exchangeable Ca(superscript 2+).

3土壤pH与交换性酸、非交换性酸含量呈极显著负相关,而与盐基饱和度呈极显著正相关,且主要受占优势的交换性Ca制约。

Based on the field surveys on a wide scale, the systematic studies were made on soil acid properties, particle fractions, exchangeable performances, saturated base, free feeric properties, clay chemical components, clay mineral types and their properties of genesis.

在大量野外调查的基础上,系统地研究了土壤的酸性特征、颗粒组成、交换性能、盐基饱和度、铁的游离度、粘粒化学组成及粘土矿物类型等发生学性质。

At the same time, LOM and CMI showed significant positive correlations with cation exchange capacity, exchangeable potassium, exchangeable calcium, total base and microelement, etc.. However, total organic matter was insignificantly related to those chemical indexes.

同时,LOM及CMI与土壤阳离子交换量、交换性钾、交换性钙、盐基总量、微量元素等呈显著或极显著正相关,但总有机质与上述土壤化学指标相关性差。

Soils from the study sites show the typical characteristics of an Andisol, being strongly acidic, with fewer exchangeable cations, a low base saturation, and an accumulation of soil organic matter with Al-compounds which are recalcitrant to decomposition. Therefore, the effects of vegetation types on the contents of SOM, TC, TN, and CEC were not significant.

本试验区为典型的火山灰土壤,土壤呈极强酸性,可交换性阳离子浓度与盐基饱和度极低,加以腐植质与活性铝形成不易为微生物分解的复合物,造成大量有机质聚积,因此不同天然植被对土壤有机质、碳氮浓度及CEC之影响均不显著。

And, the proportion of H(superscript +) in exchangeable acid showed a reverse trend. 2 Exchangeable bases, especially exchangeable Mg(superscript 2+), K(superscript +) and Na(superscript +), in various layers of the soils in the protected fields were much higher than those in the control, not only in content, but also in saturation, whereas soil exchangeable Ca(superscript 2+) did not vary much, but the base saturation and exchangeable Ca(superscript 2+) saturation decreased significantly.

2保护地各土层土壤交换性盐基总量较露地相应层次土壤均有所增加,其中交换性Mg(上标 2+)、K、Na含量均高于露地,而交换性Ca(上标 2+)含量变化不明显;保护地各土层土壤交换性Mg(上标 2+)、K、Na饱和度较露地相应层次土壤均有所增加,但盐基饱和度、交换性Ca(上标 2+)饱和度下降明显。
