This paper the evolution of the concept of soil buffer capacity, proposed a new concept, system to study soil pollution from soilbuffering to pollutant.
阐述了土壤缓冲性概念的演变，提出从缓冲性角度研究土壤污染的思路及体系。

Linear equation with one unknown, parabolic equation and nonlinear damped vibration equation well fit to describe the dynamics of Lou soilbuffering rate or value.
一元线性方程、抛物线方程及非线性阻尼振动方程对描述土壤缓冲速率及缓冲量动力学具有适应性；
