CALVEG Zones - Ecoregions

This polygon layer consists of boundaries for the ecological tile units and CALVEG (Classification and Assessment with Landsat of Visible Ecological Groupings) zone units currently being used to tile the EVEG (existing vegetation) dataset. Selected lines were added from the CalWater watershed layer where finer tile divisions were needed. Additionally, attributes from Ecological Units of California (Ecological Domain, Division, Province, Section and Subsection) have been incorporated into this layer. (see Procedures and Citation sections).本多边形图层涵盖当前用于网格化EVEG（existing vegetation，现有植被）数据集的生态格网单元与CALVEG（Classification and Assessment with Landsat of Visible Ecological Groupings，基于LandSat的可见光生态群分类与评估体系）分区单元的边界信息。针对需实施更精细格网划分的区域，从CalWater流域图层中补充选取了部分边界线条。此外，加州生态单元的相关属性信息——包括生态域（Ecological Domain）、生态分区（Division）、生态省（Province）、生态段（Section）与生态亚段（Subsection）——已被整合至本图层中，具体详见操作流程与引用说明章节。
