| 近58 a黔南地区5~20 cm平均地温年际变化呈上升趋势。气候倾向率随土壤深度增加升幅逐渐增加，近10 a浅层平均地温有明显增加的趋势。各层地温周期性分布不同。四季地温均呈增温趋势，随土壤深度增加气候倾向率逐渐增大。平均地温月变化呈单峰形势，暖月随深度增加地温递减，冷月随深度增加地温递增。空间上浅层地温呈自北向南逐渐升高的分布特征。 |

| Abstract: |
| In recent 58 years, the interannual variation of 5~20 cm ground temperature presents an upward trend in Qiannan. The trend rate of climate increases gradually with the increase of depth, the average ground temperature of shallow layer increases obviously in recent 10 years. The periodic distribution of ground temperature is different in each layer. The ground temperature of the four seasons shows an increasing trend, and the climatic tendency rate gradually increases with the increase of depth. The mean monthly ground temperature variation shows a single peak. The ground temperature decreases with the increase of the depth in the warm month and increases with the increase of the depth in the cold month. The distribution of shallow ground temperature increases gradually from north to south. |
