林地喷灌设施改造提升在森林防火中的应用研究

Research on the Application of Forest Sprinkler Irrigation Facility Renovation and Improvement in Forest Fire Prevention

为了提高森林防火能力,对林地喷灌设施的材料、功能、安装和操作技术进行了改造提升。应用改造提升的林地喷灌设施在森林火灾高发期(12月至次年3月)定期进行喷灌,提高了森林可燃物含水率和林间空气相对湿度,降低了林间地表温度。森林可燃物含水率和林间空气相对湿度较不喷水分别提高了357.6%和70.2%,林地间表温度较不喷水降低了18.3%。林地喷灌设施改造提升提高了森林防火能力,兼具灌溉和防火功能,具有一定的推广应用前景。

In order to improve the forest fire prevention capability,the materials,functions,installation,and operation techniques of forest sprinkler irrigation facilities have been renovated and improved.Regular water spraying on the application of improved forest sprinkler irrigation facilities was applied during the high incidence period of forest fires(December to March of the following year).The moisture content of forest fuels and the relative humidity of forest air were increased,and the surface temperature between forests was reduced.The average moisture content of forest fuels and the relative humidity of forest air were 40.2%and 54.8%respectively,357.6%and 70.2%higher than the control group,and the average surface temperature between forests was 4.9℃,18.3%lower than the control group.Forest sprinkler irrigation facility renovation and improvement has strengthened forest fire prevention capability,realized the functions of irrigation and forest fire prevention,which has bright prospect of marketing and application.
