土壤质量 - 土壤无脊椎动物采样 - 第1部分:蚯蚓的手工分选和提取

[中文适用范围]： 本文件规定了一种从田间土壤中采样和处理蚯蚓的方法，作为使用这些动物作为生物指示剂（例如评估土壤作为生物栖息地的质量）的先决条件。本文件适用于所有存在蚯蚓的陆地生物群落。本文件不适用于半陆地土壤（即部分水生的土壤，如沼泽、海滩、沼泽、溪流边缘），并且在极端气候或地理条件（例如高山）下可能难以使用。其他土壤生物类群（如微型节肢动物和线蚓（中型动物））的方法在ISO 23611系列的其他部分中涵盖。 [外文原描述]： This document specifies a method for sampling and handling earthworms from 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). This document is applicable to all terrestrial biotopes in which earthworms occur. This document does not apply to semi-terrestrial soils (i.e. soils that are partly aquatic, such as bogs, beaches, marshes, stream margins) and it can be difficult to use under extreme climatic or geographical conditions (e.g. in high mountains). Methods for other soil organism groups, such as micro-arthropods and enchytraeids (mesofauna), are covered in other parts of the ISO 23611 series.
