MATHEMATICAL MODELS OF SOIL ENVIRONMENTAL CAPACITY (I)--A DYNAMICS MODEL OF SOIL POLLUTION
土壤环境容量数学模型--Ⅰ.土壤污染动力学模型

Based on the principle of mass balence, a mathematical model of soil environmental dynamics was created. It can be used to determine soil environmental capacity, to analyse pollution status of soil and to predict the year when the accumulated pollutant exceeds the capacity in soil. The model can simulate the static and dynamic capacities of heavy metals and organic substances. Some models based on determined residul rate can be deduced from this model.
