土壤质量——土壤无脊椎动物的取样第3部分:附着体的取样和土壤提取

[中文适用范围]： 本文件规定了从陆地土壤中取样、处理和提取 enchytraeids 的方法，作为使用这些动物作为生物指示剂的先决条件（例如评估作为生物体栖息地的土壤质量）。 有关 enchytraeids 生态学及其在陆地环境中作为生物指示剂的用途的基本信息包含在参考书目中。 本文件适用于所有存在 enchytraeids 的陆地生境。 ISO 18400-101 中给出了一般实地研究的抽样设计。 这些细节可能会根据采样地点的气候/区域条件而有所不同，参考文献[6]给出了在实地情况下确定污染物对enchytraeids影响的概述。 本文件中给出了一些其他土壤生物群（例如蚯蚓或节肢动物）的方法，不适用于非常潮湿或淹没的土壤，并且在极端气候或地理条件下（例如在高山中）可能难以使用。 当对土壤无脊椎动物进行采样时，强烈建议描述该地点的特征（例如土壤特性、气候和土地利用）。 然而，本文件并未涵盖此类特征。 测量pH值、粒度分布、C/N比、有机碳含量和持水能力。 [外文原描述]： This document specifies a method for sampling, handling and extracting enchytraeids from terrestrial field soils as a prerequisite for using these animals as bioindicators (e.g. to assess the quality of a soil as a habitat for organisms). Basic information on the ecology of enchytraeids and their use as bioindicators in the terrestrial environment is included in the Bibliography. This document applies to all terrestrial biotopes in which enchytraeids occur. The sampling design of field studies in general is given in ISO 18400-101. These details can vary according to the climatic/regional conditions of the site to be sampled and an overview on the determination of effects of pollutants on enchytraeids in field situations is given in Reference [6]. Methods for some other soil organism groups such as earthworms or arthropods are given in ISO 23611-1, ISO 23611-2, ISO 23611-4 and ISO 23611-5. This document is not applicable for very wet or flooded soils and might be difficult to use under extreme climatic or geographical conditions (e.g. in high mountains). When sampling soil invertebrates, it is highly recommendable to characterize the site (e.g. concerning soil properties, climate and land use). However, such a characterization is not covered by this document. ISO 10390, ISO 10694, ISO 11272, ISO 11274, ISO 11277, ISO 11461 and ISO 11465 are more suitable for measuring pH, particle size distribution, C/N ratio, organic carbon content and water-holding capacity.
