Inland water macroinvertebrate occurrences in Flanders, Belgium

The Flemish Environment Agency (VMM) is performing biological water quality assessments on inland waters in Flanders (Belgium) since 1989 and sediment quality assessments since 2000. The water quality monitoring network is a combined physico-chemical and biological network, the biological component focusing on macro-invertebrates. The sediment monitoring program produces biological data to assess sediment quality. Both monitoring programs aim to provide index values, applying a similar conceptual methodology based on the presence of macro-invertebrates. The biological data obtained from both monitoring networks are consolidated in the VMM database. The dataset published contains: 283,141 records of 207 observed taxa from 4,152 monitoring sites located on more than 669 different water courses. The data are distributed to the public domain under the Creative Commons CC-BY license.

The data in this sampling event resource have been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data. It contains a core table with the events (23,829 records) and two related extensions with occurrences (305,353) and measurements (109,122). An extension record supplies extra information about a core record. The IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download here: https://ipt.inbo.be/resource?r=vmm-macroinvertebrates-events

弗拉芒环境署（Flemish Environment Agency，VMM）自1989年起，便针对比利时佛兰德斯地区的内陆水域开展生物水质评估工作，并自2000年起启动沉积物质量评估项目。水质监测网络为理化监测与生物监测相结合的复合网络，其生物监测组分聚焦于大型无脊椎动物（macro-invertebrates）。沉积物监测项目则生成用于评估沉积物质量的生物数据。两项监测项目均基于大型无脊椎动物的存在情况，采用一致的概念方法，旨在生成标准化指数值。两项监测网络获取的生物数据均整合至VMM数据库中。本次发布的数据集包含：来自669条以上不同水道的4,152个监测点位的207个观测类群的283,141条记录。本数据集以知识共享署名许可（Creative Commons CC-BY license）向公共领域开放分发。
本采样事件资源中的数据以达尔文核心档案（Darwin Core Archive，DwC-A）格式发布，该格式是生物多样性数据共享的标准化格式。其包含一个记录监测事件的核心数据表（含23,829条记录），以及两个关联扩展表：分别存储发生数据（305,353条）与测量数据（109,122条）。扩展记录用于为核心记录补充额外信息。集成出版工具（Integrated Publishing Toolkit，IPT）负责对数据进行归档，因此可作为数据存储库。本数据集与资源元数据可在此处下载：https://ipt.inbo.be/resource?r=vmm-macroinvertebrates-events
