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。The paper researched the effects of soil temperature and humidity after1h water spray on fireforest belt.The water spray method was used to measure the soil temperature and humidity from52h beforespraying and70h after spraying,and then the difference and change trend were analyzed.The results showedthat the soil temperature and humidity were significantly different(P<0.05)before and after water spray.The soiltemperature decreased by only1.8℃,an decrease of9.5%and the effect was maintained at114.4min.The soilhumidity increased by11.3%,an increase of148.7%,and the effect was maintained3days.
