Bladoppervlakte-index

De bladoppervlakte-index ofwel leaf area index (LAI) is een dimensieloos getal dat grootte van het bladoppervlak kenmerkt.

Het wordt gedefinieerd als het eenzijdig bladoppervlak per grondeenheid (LAI = bladoppervlakte / grondoppervlak) breedbladige kronen.[1] Wanneer men ook het houtachtige gedeelte van de plant meeneemt in de berekening, noemt men dit de plant area index (PAI).[2]
