Abstract: Based on MODIS MOD 13Q1 data, the spatial and temporal dynamics of normalized difference vegetation index （NDVI） and its relationship with climate factors during the growing season in Zhejiang Province from 2005 to 2018 were explored through trend analysis and correlation analysis. The results showed that the vegetation coverage in the study area was relatively good from 2005 to 2018, and the areas with high vegetation coverage were mostly in mountainous areas. The multi-year average NDVI in Zhejiang growing season was 0.654 1. The interannual variation of NDVI in the growing season showed an extremely significant increase（P<0.01）, with an average annual growth rate of 0.001 6, and the area of the study area with a significant increase of NDVI reached 23.1%（P<0.05）. The vegetation cover of the whole province was stable, and the area of low fluctuation（CV≤0.05） and relatively low fluctuation（0.05<CV≤0.10） reached 85.8%. The results of correlation analysis and multiple regression analysis showed that air temperature was significantly positively correlated with NDVI（P<0.01） in the growing period, which was the main influencing factor, and the response of vegetation to temperature and precipitation was more sensitive in the middle growing period.
