Water Body Status Classification Stour

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 Stour 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/3087 Attribution statement: © Environment Agency copyright and/or database right 2016.

水体状态分类数据基于一系列被称为质量要素（quality elements）的不同参数，用以表征各类水体的质量与状态。本数据集涵盖斯陶尔（Stour）流域内所有水体的分类历史记录。若分类采用2009年首次流域规划周期启动时确立的规则，则此类数据将被标记为‘第一周期（Cycle 1）’，数据时限截至2015年；反之，若分类采用流域规划更新后的最新规则，则数据将被标记为‘第二周期（Cycle 2）’，其时间跨度为2013年至2021年。其中，地表水的状态分类分为生态状态与化学状态两类；地下水的状态分类则分为化学状态与水量状态两类。本数据支撑《水框架指令（Water Framework Directive）》项下的流域管理规划，相关规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/3087。版权声明：© 英格兰环境署（Environment Agency）2016年享有版权及/或数据库权利，保留所有权利。
