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 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.

土壤动物是土壤生态系统中的重要组成部分。在物质的生物循环过程中,对于生命元素的转换、储存和释放,土壤动物作为中间环节具有特殊的功能性作用。 本文讨论了长白山北坡四个垂直景观带的土壤动物类群的数量和分布,分析了其化学元素含量和生物富集量。探讨了土壤动物在每公顷土地面积上对绿色植物必需的常量元素K、Na、Ca、Mg、Fe以及微量营养元素Cr、Mn、Co、Ni、Zn、Cu、Sr、Mo的转换量。

This paper analyses biological climate character and geological land form basis of the great-dam region of the Yangtze river.In this paper the environmental basis, function and the laws of evolution are studied in the light of biological system. The environmental basis is the network made up of multicomposition. The bielogical system of soil is mainly made up of soil and environmental condition as well. The function of the structure is the performance of the structure. As the land form of the great-dam region includes hills, mountains and gorges, the function of the environmental biological structure has not only the obvious properties of a horizontal belt, but the obvious difference-distinction of three-dimensional structure as well.In this paper it is on the basis of changes of level in west-east region of the great-dam and vertical difference that the structural distinction and functional strength between different regions and vertical belts are compared.

本文讨论了以下几个问题:长江三峡库区地质地貌基础及生物气候特点;用生态系统的观点和方法研究环境的结构功能和演变规律。 环境生态系统是多种自然要素所构成的网络结构。其中土壤生态系统的组成以土壤为主,也包括环境条件,结构是功能的基础,功能是结构的表现。长江三峡库区为丘陵,山地及峡谷地貌、环境生态结构功能除表现明显的水平地带性外,也具有显著钓立体结构分异特征。本文以库区的东西水平变化与垂直分异为基础,比较不同地区不同垂直带的结构特点与功能的强弱。
