Abstract

Abstract:

Based on the normalized difference vegetation index (NDVI) and enhanced vegetation index obtained from remote sensing and on temperature and precipitation data from 60 meteorological stations in Mongolia from 2001 to 2020, the logistic curve method and dynamic threshold method of the cumulative vegetation index were used to extract the vegetation green-up period in Mongolia. Partial correlation analysis was used to explore the relationship between the vegetation green-up period and the asymmetric changes in diurnal temperature in winter and spring. The results were as follows: (1) In the past 20 years, the warming rates for highest winter and spring temperatures were 0.07 ℃·a⁻¹ and 0.15 ℃·a⁻¹ (P<0.05, R²=0.33) respectively, while the change rates of the lowest winter and spring temperatures were −0.01 ℃·a⁻¹ and 0.04 ℃·a⁻¹ respectively. The change rate of the winter and spring diurnal temperature ranges were 0.08 ℃·a⁻¹ and 0.11 ℃·a⁻¹ (P<0.05, R²=0.52) respectively, showing clear seasonal differences. (2) The seasonal response of the start of the growing season to winter and spring climate warming is asymmetric, with the highest temperature and diurnal temperature range having a greater impact in winter, while the lowest temperature has a greater impact in spring; both show negative correlations. (3) The asymmetric impact of climate warming on NDVI in Mongolia is mainly manifested in spring. The highest spring temperature and spring diurnal temperature range have a mainly negative correlation with NDVI, while the lowest spring temperature has a mainly positive correlation with NDVI. This study provides an important reference in the study of the seasonal effects of climate warming on vegetation phenology and late-stage growth.

Key words: start of growing season, spring NDVI, asymmetric change, diurnal temperature range, Mongolian
