摘要: |
采用水喷淋方式,对防火林带喷淋 1 h,连续测量喷淋前 52 h 至喷淋后 70 h 的土壤温度和湿
度,对其进行差异性和变化趋势分析。结果表明,水喷淋前后的林内土壤温度和湿度差异显著(P<0.05),
喷淋后林内土壤温度下降最大值为 1.8 ℃,降幅 9.5%,降温效果维持 114.4 min;林内土壤湿度升高最大
值为 11.3 个百分点,增幅 148.7%,加湿效果维持 3 d。 |

Abstract: |
The paper researched the effects of soil temperature and humidity after 1 h water spray on fire
forest belt. The water spray method was used to measure the soil temperature and humidity from 52 h before
spraying and 70 h after spraying, and then the difference and change trend were analyzed. The results showed
that the soil temperature and humidity were significantly different (P <0.05) before and after water spray. The soil
temperature decreased by only 1.8 ℃ , an decrease of 9.5% and the effect was maintained at 114.4 min. The soil
humidity increased by 11.3%, an increase of 148.7%, and the effect was maintained 3 days. |
