Dataset Direct Download Service (WFS): Surface wetland of the SAGE de l’Avre en Eure-et-Loir (28)

In the legal sense, the Water Act of January 1992 defines wetlands as “land, whether or not exploited, usually flooded or engrown with fresh water, salted or brackish permanently or temporarily; vegetation, where it exists, is dominated by hygrophilic plants for at least part of the year”. They are also mentioned in articles 127 and 128 of Law 2005-157 on the development of rural territories (including the addition of an article L. 211-1-1 to the Environmental Code).In practice, their determination (also called “cartography” in terms of rendering) is carried out locally at the level of the basin, the region, or even the department under the supervision of the Agency, the DREAL or a departmental authority... Their suppliers and descriptions may therefore be diverse.Not included here are the so-called Ramsar areas.The Sandstone has established a dictionary “Wetland Inventory” listing the elements of a common core of their description, allowing information exchange and data sharing.

从法律层面而言，1992年1月颁布的《水法》将湿地定义为：“无论是否被开发利用，通常被淡水、咸水或半咸水永久或暂时性淹没或浸润的土地；若存在植被，则在一年中至少一段时间内以湿生植物（hygrophilic plants）为优势种。”2005年第2005-157号《农村地区发展法》（含《环境法典》新增条款L.211-1-1）的第127条与第128条也提及了湿地。实际操作中，湿地的认定（成果呈现环节也称为“湿地制图”）由流域、大区乃至省级地方机构，在管理局（Agency）、DREAL或省级主管部门的监督下开展，因此湿地数据的来源与描述方式可能存在多样性。本数据集未纳入所谓的拉姆萨尔（Ramsar）湿地。桑德斯通（Sandstone）编制了《湿地名录》（Wetland Inventory）词典，列明了湿地描述的通用核心要素，以促进信息交流与数据共享。
