Potential Natural Vegetation biomes global predictions of classes (based on predictions using the BIOMES 6000 dataset's 'current biomes' category.)
Potential Natural Vegetation (PNV) is the vegetation cover in equilibrium with climate that would exist at a given location non-impacted by human activities. PNV is useful for raising public awareness about land degradation and for estimating land potential. This dataset contains results of predictions of
- (1) global distribution of biomes based on the BIOME 6000 data set (8057 modern pollen-based site reconstructions),
- (2) distribution of forest tree species in Europe based on detailed occurrence records (1,546,435 ground observations), and
- (3) global monthly Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) values (30,301 randomly-sampled points).

潜在的自然植被生物群落的全球预测类别（基于使用BIOMES 6000数据集的 "当前生物群落 "类别的预测。
潜在自然植被（PNV）是指在某一特定地点不受人类活动影响而存在的与气候平衡的植被覆盖。PNV对于提高公众对土地退化的认识和估计土地潜力非常有用。该数据集包含以下预测结果
(1) 基于BIOME 6000数据集（8057个基于花粉的现代遗址重建）的全球生物群落分布。
(2) 基于详细的发生记录（1,546,435次地面观测）的欧洲森林树种的分布，以及
(3) 全球每月吸收光合有效辐射的分数（FAPAR）值（30,301个随机抽样的点）。
