Definition of vegetative phenology for all growth forms.

Vegetative phenology was measured in two ways; in phenological stages for shrubs and dwarf shrubs, and as a continuous measure for graminoids and forbs. For shrubs and dwarf shrubs a branch defined by the lowermost branching point was used for measurements. For forbs and graminoids, an individual ramet was used for measurements.营养生长物候（Vegetative phenology）采用两种方式开展测定：针对灌木与矮灌木，以物候期分级法进行观测；针对禾草类植物（graminoids）与非禾本科草本植物（forbs），则采用连续观测指标法。对于灌木与矮灌木，选取以最下位分枝点界定的枝条作为测定对象；对于非禾本科草本植物与禾草类植物，则选取单个分株（ramet）进行观测。
