Basic map Nature Network Brabant, Ecological connection zone (line file)

Ecological connection zones (evz) are areas or structures that should allow connection, migration and exchange of species between nature areas. They are often elongated wet and/or dry landscape elements along dikes, watercourses, roads, rail and waterways. This geographic dataset contains the evz as a line object with information about its realisation and is called basic map NNB/EVZ (NNB = Nature Network Brabant). The realisation information comes from water boards. The location of the line objects follows the decision-making in the Regulation space of the search areas for ecological connection zones (with exceptions in Brabantse Delta water authority see below). These search areas are flat objects and form a zone of 25 meters on both sides of the evz line object. This geographic dataset is based on decision-making by the Space Regulation.生态连接带（Ecological Connection Zones，EVZ）是为实现自然区域间物种连通、迁徙与物种交换而设立的区域或景观结构。其多为沿堤坝、河道、道路、铁路及通航河道分布的长条状干湿兼具的景观要素。 本地理数据集以线要素形式存储生态连接带（EVZ）数据，并附带其实施状态相关信息，命名为基础地图NNB/EVZ（其中NNB即布拉班特自然网络（Nature Network Brabant））。其实施状态信息由各水务委员会提供。该线要素的位置依据生态连接带搜索区域的空间规划决策确定（布拉班特三角洲水务委员会辖区除外，具体说明详见下文）。上述搜索区域为面状要素，以EVZ线要素为中轴线，向两侧各延伸25米形成缓冲带。本地理数据集的编制依据为《空间规划条例》的相关决策。
