土壤质量.取样.第205部分：天然、近天然和耕地调查程序指南

[中文适用范围]： 本文件提供了对自然、近自然以及耕作场地的土壤采样指导。适用于：自然和近自然场地；包括森林和林地在内的自然林区；用于农业的土地（耕地和牧场）；用于园艺的土地（包括家庭花园、小地块）；用于特殊作物种植的土地（果园、葡萄园、商业林场等）。本文件适用于现场土壤调查和评估，以及用于土壤和土壤材料的化学、地球化学、物理和生物表征的样品采集。本文件制定了设计采样方案、现场程序以及后续样品处理（运输和储存）的适当策略。它 intended 与 ISO 18400 系列的其他部分配合使用。 [外文原描述]： This document provides guidance on the sampling of soils of — natural and near-natural sites, — natural arboreal areas including forests and woods, — areas used for agriculture (arable and pasture sites), — areas used for horticulture (including domestic gardens, allotments), and — areas used for special crop-cultivation, orchards, vineyards, commercial plantations and forests, etc. It is applicable to — soil investigations and evaluations in the field, and — collection of samples for chemical, geochemical, physical, and biological characterization of soil and soil materials in the laboratory. This document sets out appropriate strategies for the design of sampling programmes, field procedures and subsequent treatment of samples for transport and storage prior to sample pretreatment (e.g. drying, milling). It is intended to be used in conjunction with the other parts of the ISO 18400 series. Attention is, in particular, drawn to the requirements concerning collection, handling and storage of soil for assessment of biological functions in ISO 18400-206. NOTE 1 Groundwater and surface water can be adversely impacted by agricultural and related activities, such as nitrates and pesticides, and by translocation of soil particles. In turn, knowledge about water quality can provide information about possible sources of groundwater contamination or contaminating run-off. Investigation of groundwater and surface water quality is outside of the scope of this document; relevant guidance is given in the ISO 5667 series of standards. ISO 15175 provides guidance on the relationship between soil properties and groundwater quality. NOTE 2 It could also be appropriate to investigate ambient air, vegetation, potable water supplies and a variety of other media depending on the findings of the preliminary investigation.
