摘要:

通过统计与分析西藏气候变化趋势及特点,分析2022年度西藏平均气温、降水、日照,季节气候特征及其对农业生产的影响。研究得出2022年平均气温偏高、降水量偏少、日照时数偏多,并通过对主要农作物的生育期气象条件分析得出,农田土壤蒸腾加剧,墒情下降迅速,苗期长势总体偏弱,从而影响粮食总产量。总体来看气象条件对农业生产的影响利弊均有,且利大于弊。为保障农业气象服务质量,确保粮食安全,抓好今后粮食归仓气象保障服务,提出了农业生产气象服务建议,为西藏农业生产和防灾减灾提供科学依据。

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
