Water Body Status Classification Severn England AWB

Water body status classification data indicates the quality or status of water bodies across a range of different parameters known as quality elements. This dataset includes the classification history of all water bodies in the Severn England AWB catchment. Data may be flagged as 'Cycle 1' if the classification uses the rules initiated in 2009 when the first cycle of river basin planning began. These data end in 2015. Or the data may be flagged as 'Cycle 2' if the classification uses the latest rules used in the updated river basin plans. These data begin in 2013 and will end in 2021. For surface water bodies status classification is grouped into ecological and chemical status and for groundwater bodies they are grouped into chemical and quantitative status. This data supports the Water Framework Directive river basin management plans that can be found here: https://www.gov.uk/government/collections/river-basin-management-plans-2015 and is available to view interactively here: http://environment.data.gov.uk/catchment-planning/ManagementCatchment/2004 Attribution statement: © Environment Agency copyright and/or database right 2016.

水体状态分类数据，是依托一系列被定义为水质要素的不同参数，对各类水体的质量与状态进行分类的数据集。本数据集涵盖英格兰塞文（Severn）流域AWB集水区内所有水体的分类历史。若分类采用2009年首次流域规划周期启动时制定的规则，则该数据将标记为“周期1（Cycle 1）”，此类数据的时间范围截至2015年。若分类采用更新后流域规划所使用的最新规则，则该数据将标记为“周期2（Cycle 2）”，此类数据的时间跨度为2013年至2021年。其中，地表水体的状态分类分为生态状态与化学状态两类，地下水体的状态分类则分为化学状态与水量状态两类。本数据集服务于《水框架指令（Water Framework Directive）》流域管理计划，相关计划可通过以下链接查阅：https://www.gov.uk/government/collections/river-basin-management-plans-2015；同时可通过以下链接进行交互式浏览：http://environment.data.gov.uk/catchment-planning/ManagementCatchment/2004。版权声明：© 英格兰环境署（Environment Agency）2016年版权及/或数据库权益，保留所有权利。
