Historic Woody Vegetation Mapping of the NSW Wheat-belt VIS_ID 1606

The vegetation of the Central Division of NSW was classified and mapped (Cobar-Nyngan-Gilgandra), Nymagee-Narromine-Dubbo 1:250 000 map sheets) as part of the NSW NPWS wheat-belt mapping series. The vegetation classification was derived using traditional API and quantitative analysis of data from 428 field sites. Analyses included heirarchical classification in PATN to define floristic groups, then Fidel and ANOSIM to elucidate the characteristic species of the groups and explore the consistency of these relationships and various levels of similarity. Maps and descriptions show the floristic composition and structure, the geographic distribution of assemblages, the current extent, and shape and degree of connectivity of vegetation and changes in native woody vegetation cover over time.\r\n\r\nVIS_ID 1606\r\n\r\nANZLIC: ANZNS0208000147

本数据集作为新南威尔士州（New South Wales, NSW）国家公园与野生动物服务局（National Parks and Wildlife Service, NPWS）小麦带制图系列的组成部分，针对新南威尔士州中部区域（覆盖Cobar-Nyngan-Gilgandra、Nymagee-Narromine-Dubbo 1:250000比例尺图幅）完成了植被分类与制图工作。

本次植被分类依托428个野外样点的数据集，采用传统API与定量分析方法开展。

分析流程如下：首先通过PATN（模式分析包，Pattern Analysis Package）执行层级分类以界定植物区系群；随后借助Fidel与ANOSIM（相似性分析，Analysis of Similarities）阐明各植物区系群的特征物种，并探究此类物种关联的一致性以及不同等级的相似性水平。

本数据集附带的制图与描述内容，展示了植被的植物区系组成与结构、植被群落的地理分布格局、当前植被覆盖范围、植被的形态特征与连通程度，以及本土木本植被覆盖度随时间的变化情况。
