Figure 3: Variations in change rate of standardized data representing climate variables or net primary production at the monthly or seasonal scales in tropical or subtropical evergreen broadleaved forests from 1981 to 2012.

Soil water content (mm) was obtained from the plots located at four stations (AL, BN, DH, HT). The slope obtained from a least square linear regression was used to estimate the rates (the letter “a” above histogram bar signifies the coefficient by statistical significance test (P < 0.05).
