Short summary
We used hemispherical photography to measure LAI values in three subtropical forests from April 2014 to January 2015. Spatial heterogeneity of LAI and its controlling factors were analysed using geostatistical methods and the generalised additive models (GAMs), respectively. Our results showed that LAI values differed greatly in three forests and their seasonal variations were consistent with plant phenology. Stand characters significantly affected the spatial variations in LAI values.
