| 摘 要： | 对镇江地区1984—2019年家燕始见、绝见及同期气温、风速、降水、日照等气象资料开展对比分析结果表明，近36年镇江地区家燕始见期在波动变化中呈现提前的趋势，以4d/10a的速率提前。绝见日期在波动变化中呈现推后的趋势，以5d/10a的速率推后。间隔期在波动变化中呈现延长的趋势，以9d/10a的速率延长；近36来镇江地区平均气温呈极显著的上升趋势，平均风速呈极显著的下降趋势，日照时数呈弱减少趋势，累积降水量呈弱增加趋势；四季的平均温度均呈极显著的上升趋势，以春季最为显著。四季的风速均呈极显著的减小趋势，其中春、夏季的降幅较大。日照时数整体呈减少的趋势，其中秋季的总日照时数减少最为明显。累积降水量变化趋势均不明显。影响家燕始见期和间隔期的敏感气候因子是4月气温和5月日照时数，3月平均风速是影响其绝见期的敏感气候因子。

| Abstract: | The results of comparative analysis of meteorological data such as the first seen date, the last seen date, temperature, wind speed, precipitation, sunshine and other meteorological data in Zhenjiang area from 1984 to 2019 showed that, In the past 36 years, the first seen date of swallows in Zhenjiang area has shown a trend of advancement in fluctuations, with a rate of 4 days/10 years. The last seen date has a trend of being postponed in volatility, at a rate of 5 days/10 years. The interval has been prolonged in the fluctuating changes, extending at a rate of 9 days/10 years; in the past 36 years, the annual average temperature in Zhenjiang has shown a very significant upward trend, the annual average wind speed has shown a very significant downward trend, and the annual sunshine hours shows a weak decreasing trend, and the cumulative precipitation shows a weak increasing trend; the average temperature of the four seasons shows a very significant upward trend, especially in spring. The wind speed in the four seasons showed a very significant decreasing trend, among which the decrease in spring and summer was larger. The total sunshine hours showed a decreasing trend, and the total sunshine hours in autumn decreased most obviously. The cumulative precipitation change trend is not obvious. The sensitive climate factor that affects the first seen date and interval period of the swallow is the temperature of April and the sunshine hours in May, and the average wind speed in March is the sensitive climate factor that affects its extinction period. |
