Map Viewing Service (WMS) of the dataset: Protection zone for a catchment feeding area

In response to the requirements of the Water Framework Directive, the Water and Aquatic Environments Act of 30/12/06 strengthened the
control of diffuse pollution from agricultural sources through the creation of protection zones for catchment feeding areas. The implementation of this new resource protection system leads to the delineation of catchment foraging areas (sometimes also referred to as catchment feeding basins or LACs) that include AAFC protection areas.
The protection zone is defined by crossing the mapping zoning of intrinsic vulnerability and zoning of agricultural pressures.
In the case of surface water abstractions, the definition of a protection zone within the watershed upstream of the intakes is based on the identification of flows (slide, drainage, ditches, alluvial and river exchanges) and the identification, by territorial diagnosis, of agricultural pressures and areas likely to play the most important role in the degradation of the water resource.

为响应《水框架指令》（Water Framework Directive）的相关要求，2006年12月30日颁布的《水与水生环境法》（Water and Aquatic Environments Act）通过设立集水区补给区保护带，强化了对农业面源污染的管控力度。
该新型资源保护体系的实施，需划定包含AAFC保护区域的集水区补给区（catchment foraging areas，部分场景亦称为集水补给盆地或LACs）。
保护带的划定需通过固有脆弱性制图分区与农业压力分区的空间叠加分析完成。
针对地表水取水场景，取水口上游流域内保护带的划定需基于两项识别工作：一是识别各类水文径流过程（坡面滑流、排水系统、沟渠、冲积层与河流间的水文交换）；二是通过区域诊断明确农业压力源及对水资源退化起到关键影响的区域。
