2016 SoE Land Extent of modification of major vegetation groups, as assessed by VAST

Data showing the extent of modification of major vegetation groups (as assessed by Vegetation, Assets, States & Transitions (VAST)). Data includes the extent of major vegetation groups (in million hectares) prior to 1750; and the extent of modification these groups have undergone, since 1750.\r\n\r\nAnalysed data was prepared by the Australian Government Department of Environment and Energy using NVIS 4.1 & data from ABARES (Vegetation Assets, States and Transitions dataset). For further information on these datasets see: http://www.environment.gov.au/about-us/environmental-information-data/open-data AND http://data.daff.gov.au/anrdl/metadata_files/pa_vast_g9abll0032008_11a.xml\r\n\r\nThe data has been used by the Department of Environment and Energy to produce Figure LAN30 in the Land theme of Australia State of the Environment 2016, available at \r\nhttps://soe.environment.gov.au/theme/land/topic/2016/vegetation-0#land-figure-LAN30本数据集呈现了主要植被群落的改造程度，该评估由植被资产、状态与转移（Vegetation, Assets, States & Transitions, VAST）体系完成。数据集涵盖1750年之前各主要植被群落的覆盖范围（单位：百万公顷），以及1750年以来这些植被群落所经历的改造程度。 本次分析所用数据由澳大利亚环境与能源部基于国家植被信息系统（National Vegetation Information System, NVIS）4.1版本以及澳大利亚农业与资源经济科学局（Australian Bureau of Agricultural and Resource Economics and Sciences, ABARES）的植被资产、状态与转移数据集整理得到。如需了解上述数据集的更多信息，请访问以下链接：http://www.environment.gov.au/about-us/environmental-information-data/open-data 与 http://data.daff.gov.au/anrdl/metadata_files/pa_vast_g9abll0032008_11a.xml。 该数据集已被澳大利亚环境与能源部用于制作《2016年澳大利亚环境状况报告》土地主题中的LAN30号图表，相关内容可通过以下链接查阅：https://soe.environment.gov.au/theme/land/topic/2016/vegetation-0#land-figure-LAN30。
