This paper presents a kind of model on soil environmental capacity according to the stability of soil ecosystem. The models characterize the influence of pollutants upon the components of the ecosystem and the relations among the components. The models include the original equiratio series model as a special case.

本文从生态学观点出发,根据对土壤生态系统稳定性的认识,提出一种关于土壤环境容量的结构模型,为容量模型研究探索了一条新的道路。该模型的特点是考虑到污染物对系统中各组分的影响及组分之间的相互关系,从而使模型研究开始涉及容量问题的实质。本模型并把已有的关于土壤环境容量的等比级数模型作为一种特例包括在内。 本文还列举了在北京东南郊土壤系统实际研究中应用该模型的计算过程及所得的若干结果。

The soil animals are an important integral part of the soil ecosystem.They, as a medium, perform a function in the transformation, storage and release of vital nutrients in the process of material biocycles.The distribution and the number of the soil animal population of four vertical zones in the northern slope of the Changbai Shan Mountain have been presented in the paper.The content and the bio-concentration of various chemical elements in the body of soil animals have also been determined.The capacity of the soil animals in one hectare area of land to transform the macronutrients (K, Na, Ca, Mg, Fe) and the micronutrients (Cr, Mn,Co, Ni, Zn, Cu, Sr, Mo) essential for green plant growth has been studied.
