HPNV – HPNV Location Property Base Level

Present-day potential natural vegetation: The map of current potential natural vegetation (HPNV) depicts as mapping units the final societies of vegetation development (usually forest societies) that exist without human influence under present-day location conditions. It thus represents a vegetation-study location map. Visible from a scale of 1:100.000 or larger.当代潜在自然植被：当前潜在自然植被（HPNV）地图以植被发育的顶级群落（通常为森林群落）作为制图单元，此类群落在当前立地条件下不受人类活动干扰即可自然存续，因此该地图属于植被研究立地图，可在1:100000及更大比例尺下清晰识读。
