Vegetation phenology changes play a key role in the carbon and nutrient cycle of terrestrial ecosystems. Phenology findings based on satellite observations have mainly concentrated on the northern hemisphere or Eurasia and the American continent, with few small‐scale studies on special climate environments. In this study, we used five methods to extract the Start of Growing Season (SOS), End of Growing Season (EOS) and Length of Growing Season (GSL) dates from NDVI records for the Korean Peninsula from 1982 to 2015, and determined the time correlation between SOS, EOS and maximum temperature (Tmax) and minimum temperature (Tmin). In general, phenological changes in the Korean peninsula vary from the findings drawn from the northern hemisphere scale. The SOS advance rate on the Korean peninsula is about 0.01 days / year, the fall phenology delay rate is about 0.24 days per year (p <0.05), and the growing season extension rate is about 0.23 days/year. By investigating the phenology of North Korea and South Korea separately using the 38‐line boundary, we found no statistically significant changes in SOS and GSL in North Korea. At the same time, SOS, EOS, and GSL in South Korea have changed significantly over this period. The prolongation of the growing season on the Korean Peninsula is mainly due to the delayed phenology of autumn. Vegetation phenology in South Korea’s marine climate is more strongly influenced by Tmin.

The vegetation is feedback on environmental change due to global warming. Also, the growth status of vegetation and the coverage area of vegetation are greatly affected by the environmental changes. The quantitative change of vegetation growth status is the primary task of vegetation response to environmental changes. In this study, the Global Inventory Modeling and Mapping Studies (GIMMS) based Normalized Difference Vegetation Index (NDVI) and CRU climate data are used to analyze the spatio‐temporal characteristics of vegetation greening evolution and its response to climate change from 1982 to 2015 in the Korean Peninsula by applying the partial correlation and trend analysis. The results show that the average NDVI value of the Korean Peninsula in the period 1982‐2015 was 0.68, among which the average NDVI in North Korea and South Korea was 0.69 and 0.67, respectively. The NDVI of the Korean Peninsula between 1982 and 2015 increased by 0.6x10‐3 year‐1. The increasing trend prior to and after 1998 was 2.5×10‐3 year‐1 and 0.9×10‐3 year‐1, respectively. During the 1982‐2015 years, the NDVI of DPRK and South Korea have grown mainly with the trend of 0.2×10‐3 year‐1 and 1.1×10‐3 year‐1, respectively. According to the analysis of NDVI and climatic factors, the distribution of NDVI in the three‐time series of Korean Peninsula is consistent in spatial distribution. According to the results of partial correlation analysis of climate factor and NDVI distribution in Korean Peninsula, the region has significant partial correlation with temperature change. The climate factor of temperature is the main driver of NDVI change, which plays a key role in controlling NDVI change accumulation.
