## **摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）从HUN流域数据集衍生而来。源数据集的相关信息已在本元数据声明的谱系（Lineage）字段中注明。本衍生数据集的生成流程已在本元数据声明的历史（History）字段中予以说明。

亨特次区域内主要河流及其主要支流的流域范围。本数据集定义了以下各流域的面积，单位为平方千米：

Hunter：
穆南溪（Moonan Brook）
斯图尔特溪（Stewarts Brook）
帕特森河（Paterson River）
威廉姆斯河（Williams River）
佩奇溪（Pages Creek）
佩奇河（Pages River）
古尔伯恩河（Goulburn River）
沃伦比溪（Wollombi Brook）
Macquarie Tuggerah：
多拉溪（Dora Creek）
怀翁河（Wyong River）
奥林巴溪（Ourimbah Creek）

## **数据集历史**

亨特次区域内主要河流及其主要支流的流域范围。相关流域面积已在上下文说明的表格中列明，其计算基于形状文件（shapefile）Hunter_Major_Tributaries_Projected.shp。
该形状文件由亨特流域形状文件衍生而来，具体步骤为：聚合以下选定的流域，再根据下述投影参数进行定义：

PROJCS["GDA_1994_Albers",GEOGCS["GCS_GDA_1994",DATUM["D_GDA_1994",SPHEROID["GRS_1980",6378137.0,298.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Albers"],PARAMETER["False_Easting",0.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",132.0],PARAMETER["Standard_Parallel_1",-18.0],PARAMETER["Standard_Parallel_2",-36.0],PARAMETER["Latitude_Of_Origin",0.0],UNIT["Meter",1.0]]

所涉流域列表如下：
Hunter
穆南溪（Moonan Brook）
斯图尔特溪（Stewarts Brook）
帕特森河（Paterson River）
威廉姆斯河（Williams River）
佩奇溪（Pages Creek）
佩奇河（Pages River）
古尔伯恩河（Goulburn River）
沃伦比溪（Wollombi Brook）
Macquarie Tuggerah
多拉溪（Dora Creek）
怀翁河（Wyong River）
奥林巴溪（Ourimbah Creek）
