Through continuous bathe equilibrium experiments, the release of aluminum and dissolved organic matter ( DOM ), and mobility of heavy metals affected by simulated acid rain in contaminated acidic red soil and yellow red soil were studied. 在模拟酸雨作用下,研究了重金属污染和未污染的酸性红壤和黄红壤中铝和水溶性有机质的溶出以及对重金属活动性的影响。
The results showed a decrease of pH and base saturation, and increase content of exchangeable acidity in both uncontaminated and contaminated red soil and yellow red soil within the pH decreasing of simulated acid rain, significantly. 结果表明,随模拟酸雨pH值下降,土壤pH值和盐基饱和度明显降低,而交换性酸度明显增加,污染土壤中交换性氢含量比未污染土壤高,而交换性铝含量比未污染土壤低。

The Adaptability of Trees to the Secondary Yellow Red(YR) Soil in the Mountain Ranges in Zhejiang 浙江省山地次生黄红壤的宜林特性
The resultshows : 1.the soil erodibility of seven soils is yellow earth > brown purple soil > red brown purplesoil > grey alluvial soil > red purple soil > yellow red purple soil > darkbrown purple soil; 结果表明:(1)7种土壤的抗蚀能力大小依次为:冷沙黄泥>棕紫泥>红棕紫泥>灰色潮土>红紫泥>黄红紫泥>暗棕紫泥;
