Sensitive areas — WMS

Downloaded from the Geoportal NIPP — http://geoportal.nipp.hr/hr Sensitive areas are areas where, in order to achieve water quality objectives, a higher level of waste water treatment than secondary treatment in agglomerations with a total load of more than 10,000 p.e. (population equivalent) is required before the discharge of treated urban waste water into the water bodies of the sensitive area. More advanced treatment processes reduce the input primarily of nitrogen and phosphorus compounds into water bodies and, where appropriate, reduce the intake of other pollutants that would adversely affect the quality of the aquatic environment. Each sensitive area has an associated catchment area. All provisions applicable to the sensitive area concerned shall apply mutatis mutandis to the catchment of sensitive areas. The Danube RBD in Croatia has been identified as a catchment of a sensitive area located outside the territory of the Republic of Croatia. The corresponding sensitive area is the Danube Delta area when flowing to the Black Sea. Position data are presented in the Croatian Terrestrial Reference System 1996 Transvers Merkator projection (HTRS96/TM). The Spatial Preview Service (WMS Service) of sensitive areas displays two layers: the catchment layer of sensitive areas (green shraffed) and the layer of sensitive areas (green fill-eutrophic area, purple fill-area intended for the abstraction of water for human consumption, orange fill-protected area of nature).本数据集源自NIPP地理门户网站（Geoportal NIPP）——http://geoportal.nipp.hr/hr。敏感水域是指为达成水质目标，需在总负荷超过10000人口当量（population equivalent，简称p.e.）的集聚城镇区域内，采用高于二级处理的更高等级污水处理工艺，再将经处理的城镇污水排放至该敏感水域水体中的区域。更先进的处理工艺可主要降低氮、磷化合物向水体的输入量，同时酌情削减其他会对水生环境质量造成不利影响的污染物输入。每一处敏感水域均对应专属汇水区域。所有适用于该敏感水域的规定，均应比照适用于该敏感水域的汇水区域。克罗地亚境内的多瑙河流域分区（Danube RBD）被认定为一处位于克罗地亚共和国境外的敏感水域的汇水区域。该对应敏感水域为汇入黑海的多瑙河三角洲片区。点位数据采用克罗地亚1996国家大地坐标系横轴墨卡托投影（Croatian Terrestrial Reference System 1996 Transvers Merkator projection，缩写HTRS96/TM）进行组织与呈现。敏感水域空间预览服务（Spatial Preview Service，即WMS服务）包含两个图层：一是敏感水域汇水区图层（绿色晕渲），二是敏感水域本体图层——绿色填充代表富营养化区域，紫色填充代表饮用水取水保护区，橙色填充代表自然保护区域。
