Cultural-historical values map

This national dataset contains the areas that provinces have designated as part of the cultural-historical values map. This dataset is used for the Nature Information Map (IKN). The IKN is an initiative of the joint provinces and offers a national and up-to-date picture of where rules apply to nature.本国家级数据集收录了各省划定纳入文化历史价值地图的区域。该数据集服务于自然信息地图（Nature Information Map，简称IKN）。IKN由多省份联合发起，旨在呈现全国范围内当前自然保护相关规则的适用情况，提供全国性的最新全景图景。
