Abstract: Heilongjiang Province is the main crop producing area in China.In the 20th century,the temperature rose obviously,and the rainfall distribution was uneven,which was vulnerable to drought disasters.In order to understand the characteristics,frequency,development trend and meteorological factors of field drought in different regions of Heilongjiang Province,based on the temperature vegetation drought index（TVDI）,combined with the trend analysis method,the characteristics of drought change and development trend in Heilongjiang Province in the past 22 years were explored, and the main meteorological factors causing drought change in the province and the relationship between meteorological drought index were discussed.The results showed that the TVDI of the four districts in 2000—2010 was higher and more prone to drought.In 2013 and 2019,it was a humid year,and the Songnen Plain in the four districts was in a drought state for many years.From the month analysis,May and September were prone to drought,especially in the Songnen Plain,and July was often in a wet state,indicating that the province was prone to drought in spring and autumn,and wet in summer.The frequency of drought in Daxing’ an Mountains and Xiaoxing’ an Mountains,Sanjiang Plain,Zhangguangcai Mountains and Songnen Plain were 70.00%,80.91%,85.45% and 92.73%,respectively,during the 110 months of crop growth season.The intensity was mainly light drought and moderate drought.During the study period,only the Songnen Plain had a 10% probability of severe drought.The frequency and intensity of spring drought in this area were the highest,and the drought in Daxing’an Mountains and Xiaoxing’an Mountains was the least affected.In the past 22 years,the drought trend in Heilongjiang Province has been basically stable and decreasing,and the drought trend in the eastern part has increased slightly.In the monthly drought trend,there was a significant increase in June,and the area accounted for 61.08%.In May,July,August and September,the trend was basically stable.The change of TVDI in Heilongjiang Province mainly depended on rainfall,and meteorological drought will lead to agricultural drought.The annual TVDI was negatively correlated with annual rainfall,and all pass the extremely significant test of P＜0.01.The relationship between TVDI and temperature was not significant,which is related to the land type studied in this paper.
