Classification of aquatic ecosystems in the Murray-Darling Basin: 2017 update

This is the 2017 update to the classification of aquatic ecosystems in the Murray-Darling. It is a compilation of river, lake, wetland, riparian and floodplain mapping for the Murray-Darling Basin using the best available mapping from state jurisdictions (South Australia, Victoria, Queensland and New South Wales), Australian Government agencies and other organisations. Data sources range in scale from 1:,000 to 1:250,000. The interim Australian National Aquatic Ecosystem (ANAE) classification framework has been applied to all wetland polygons varying by system type (lacustrine, palustrine, riverine, estuarine and springs. Attribute values and final wetland types are included in the attribute data table.

本数据集为墨累-达令（Murray-Darling）流域水生生态系统分类的2017年更新版本。数据集汇编了该流域的河流、湖泊、湿地、河岸带及洪泛平原测绘成果，所用最优可用数据来源于澳大利亚各州管辖机构（南澳大利亚州、维多利亚州、昆士兰州、新南威尔士州）、澳大利亚联邦政府机构及其他组织。数据源比例尺覆盖1:1000至1:250000区间。本数据集采用临时版澳大利亚国家水生生态系统（Australian National Aquatic Ecosystem, ANAE）分类框架，对所有按系统类型划分的湿地面要素完成分类，系统类型涵盖湖相、草本湿地相、河流相、河口相及泉眼型。属性值与最终确定的湿地类型均已收录于属性数据表中。
