Vegetation phenology is the intra-annual rhythm of the start, progression, and ending of vegetation growth. It is widely used as a ‘footprint’ of global change. Phenology modulates carbon, water, and energy exchanges between the biosphere and the atmosphere. It also controls periods of pollen production and thus influences allergy seasons. My doctoral study aimed to understand response of vegetation phenology to global change. My dissertation has:
There are currently three published papers (listed below) and another one in review (listed here)
We developed a model to quantify how daily phenological development responds to climate change and extreme weather eventts.
We found that amplitude of urbanization, quantified as changes of %ISA, can compensate the negative effects (delayed SOS or advanced EOS) and amplify the positive effects (earlier SOS or later EOS) of climate change on temporal variations of LSP in most climate zones (except the dry climate)
