Abstract:

Through statistics and analysis of the trend and characteristics of climate change in Tibet, we analyze the average temperature, precipitation, sunshine, seasonal climate characteristics and their impact on agricultural production in Tibet in 2022. The study concludes that in 2022, the average temperature was high, precipitation was low, and sunshine hours were high. Through the analysis of meteorological conditions during the reproductive period of major crops, it is concluded that the transpiration of farmland soil is intensified, the moisture content decreases rapidly, and the seedling growth is weak in general, which affects the total grain output. In general, meteorological conditions have both advantages and disadvantages on agricultural production, and the advantages outweigh the disadvantages. In order to safeguard the quality of agricultural meteorological services, ensure food security, and grasp the meteorological guarantee services for the future grain return to the warehouse, the meteorological service recommendations for agricultural production are put forward to provide a scientific basis for agricultural production and disaster prevention and mitigation in Tibet.

Key words: climate condition, influence of agricultural production, meteorological disaster
