Abstract:

The aims are to reveal the characteristics of agro-meteorological climate resource and main meteorological disasters during the growth of Korla Fragrant Pear, and to provide scientific advice to adapt to climate change. The characteristics of climate change during the growth period of Korla Fragrant Pear and meteorological disasters were analyzed by Mann-Kendall mutation detection, climatic tendency rate and correlation test, based on the observation data of Korla Meteorological Stations from 1981 to 2021. The results showed that the average temperature, ≥10℃ accumulated temperature and sunshine hours showed significantly increasing trend during the growing period of Korla Fragrant Pear. Precipitation showed a weak decreasing tendency. The number of gale days showed an obvious decreasing tendency, but it fluctuated greatly. Over the past 40 years, the germination and flowering period of Korla Fragrant Pear shifted to an earlier date, the fruit maturity and total growth period was prolonged. Abundant solar heat resource was conducive to the formation of yield and good quality of Korla Fragrant Pear, under climate change. Gale and hail were the main meteorological disasters during the growth of Korla Fragrant Pear. The research results provide a basis for the scientific use of climate resources and disaster prevention and mitigation.
