标准摘要
[中文适用范围]： 本国际标准为沿海地区的环境影响评估和监测的滨海、滨海和滨海下硬质基质的海洋生物调查提供了指导。 本国际标准包括： - 制定抽样方案； - 调查方法； - 物种鉴定；以及 - 数据和收集材料的存储。 本国际标准规定了环境监测的最低要求。 这些方法仅限于调查以及半定量和定量记录技术，对动植物群造成的破坏很小。 实际上，这是指现场直接记录和摄影。 本国际标准未涵盖通过刮除生物体进行采样、使用抽吸采样器等方法，但此类技术可作为补充，以获取小型物种或隐藏物种的信息。 [外文原描述]： ISO 19493:2007 provides guidance for marine biological surveys of supralittoral, eulittoral and sublittoral hard substrate for environmental impact assessment and monitoring in coastal areas. It comprises development of the sampling programme, survey methods, species identification and storage of data and collected material. ISO 19493:2007 specifies the minimum requirements for environmental monitoring. The methods are limited to surveys and semi-quantitative and quantitative recording techniques that cause little destruction of the fauna and flora. In practice, this refers to direct recording in the field and photography. Sampling by scraping off organisms, use of a suction sampler, etc. are not covered in ISO 19493:2007.
