Abstract：
Phenology is a discipline and a comprehensive indicator of vegetation cycles and their responses to climate and environment changes. Forest Phenology is a comprehensive biological index to reflect the influence of short-term or long-term climate change on forest growth stages. With aid of remote sensing technology, we develop a model to calculate the data from phenological observation points into region scale. MODIS provides time-series information both in seasonal and annual changes to study the phenology. Based on MODIS Enhanced Vegetation Index (EVI) from 2000-2010, we extracted forest phenological variables using percentage thresholds method in Northeast China, which include start of growing season (SOS), end of growing season (EOS) and length of growing season (LOS). The phenological data from published papers and field observed data in the same area were used to validate the results. The validation indicate that forest phenophase from MODIS EVI data is feasible.Browse
