Water Body Status Classification Test and Itchen

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 Test and Itchen 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/3097 Attribution statement: © Environment Agency copyright and/or database right 2016.

水体状况分类数据揭示了跨多种不同参数的水体质量或状态，这些参数被称为质量要素。该数据集涵盖了Test和Itchen流域内所有水体的分类历史。若分类采用2009年启动的首个流域规划周期的规则，则数据可能被标记为'Cycle 1'。此类数据截止于2015年。若分类采用更新后的流域规划中使用的最新规则，则数据可能被标记为'Cycle 2'，此类数据始于2013年，并将持续至2021年。对于地表水体状况分类，分为生态和化学状态；对于地下水体，则分为化学和定量状态。这些数据支持《水框架指令》的流域管理计划，可在以下链接查阅：https://www.gov.uk/government/collections/river-basin-management-plans-2015，并可在此进行交互式查看：http://environment.data.gov.uk/catchment-planning/ManagementCatchment/3097。版权声明：© 环境署版权和/或数据库权利2016。版权所有。
