低丘陵山坡地逆温趋势分析

Analysis of the trend of temperature inversion by hill slopes

  • 摘要: 本研究通过探讨晴夜与非晴夜低丘陵山坡地逆温趋势规律结果表明:出现寒冻害的晴夜的低 丘陵山坡地随相对坡位升高,与坡底温差增大,相对坡位与温差存在显著回归 关系,逆温最高出现在山坡中上部,最低气温值出现在坡底;非晴夜不同相对坡位温差不大, 最低气温均高于0℃,果树无冻害现象发生。晴夜最大逆温为3.3℃,不同坡向对温差变化幅 度影响不大。

     

    Abstract: The trend of temperature inversion on fine nights and no-fine nights was discussed. Results indicate that when freezing hazard happens in hilly areas on fine nights, with hoist of relative slope of observation point the temperature difference from the bottom of the slope increases. A regression relation exists between relative slope observation point and temperature difference. Highest temperature inversion appears at the middle of the hill and lowest temperature inversion appears at the bottom of the slope. No significant difference in temperature occurs by changing the relative slope observation point. Fruit trees are not injured by freezing and the lowest temperature is always higher than 0℃. The highest temperature difference is 3.3℃ in fine night. The temperature difference does not change significantly among different slope direction.
