Victorian Bioregions - Mapped at 1:100,000 (version 3.0 - May2004)

This dataset delineates Victorian biogeographic regions (Victorian bioregions) that capture the patterns of ecological characteristics in the landscape, providing a natural framework for recognising and responding to biodiversity values. Victorian bioregions form part of the national framework for the terrestrial environment, the Interim Biogeographic Regionalisation for Australia (IBRA). The boundaries are aligned with pre-1750 ecological vegetation class boundaries mapped at 1:100,000. The dataset upgrades the VBIOREGION250 dataset which was primarily based in 1:250,000 landsystem boundaries.

本数据集界定了维多利亚州生物地理区（Victorian bioregions），该区域刻画了景观内的生态特征分布格局，可为识别与保护生物多样性价值提供天然的分析框架。维多利亚州生物地理区是澳大利亚陆地环境国家生物地理框架——《澳大利亚临时生物地理分区》（Interim Biogeographic Regionalisation for Australia, IBRA）的组成部分。该数据集的边界与以1:100000比例尺制图的1750年以前生态植被类边界保持一致。本数据集对VBIOREGION250数据集进行了升级，后者最初以1:250000比例尺的土地系统边界为依据构建。
