森林是一种重要的生态资源,在维护生物多样性上起着重要的作用.但是全球气候的变化使得自然灾害的发生愈加频繁,其中森林火灾所面临的形势更加严峻,不仅导致森林面积减少,更威胁着人类的生存环境和生态文明发展.在森林火灾扑救中,森林航空消防的优势逐渐凸显,其特殊的作业方式减少了地面灭火人员的投入,最大限度地避免人身伤害,且灭火效果良好,能够有效降低火灾的危害程度.因此,在当前的森林火灾扑救工作中应重视航空消防的作用,以便稳定森林面积,维持生态平衡,维护生物多样性.基于此,该文就森林航空消防在森林火灾扑救中的应用进行分析,同时分析了当前限制森林航空消防的一些因素并提出相应建议,以期能够提高森林航空消防的应用价值.

森林火灾对生态环境的破坏影响巨大,火灾会造成大量植物、动物灭亡,森林蓄积量减少,水土流失严重,加剧土地荒漠化,影响生态平衡,阻碍林业可持续发展.航空消防在森林灭火救援中发挥着重要作用.但当前森林航空消防工作问题较多,严重影响森林防火工作效率及质量.在此背景下,做好森林航空消防管理工作意义重大.基于此,该文首先分析了森林航空消防工作现状,其次探讨了森林航空消防工作中存在的问题及对策.

森林防火是林业类型保护区的法定任务,有效保护防护区内的森林、生物资源,对于防护区内生态安全的维护具有十分重要的意义.我国地域辽阔,气候多样,森林种类繁多,致使森林防火任务十分艰巨.目前,我国为了确保国民经济的持续发展,实施了生态可持续发展策略,加大了森林生态保护力度.基于此,从我国森林防火现状出发,分析森林防火中存在的问题,结合防护区的实际情况,提出具有针对性的对策和建议.

This paper chooses the ultra-short-wave radio station and the related auxiliary equipment to test the airspace communication of the aviation forest protection in the light of the existing problems in the use of mobile communication of air-to-ground communication support techniques of aviation forest protection in Guangdong province. The test results are as follows: when the flight true height is 300 m, the maximum air-to-ground communication distance is up to 10 km, airborne MD—780G vehicle and ground PD—780 handheld communication between the air-to-ground two-way communication distance up to 30 km, the one-way communication to the farthest up to 60 km, MD—780G vehicle space between the air-to-ground two-way communication distance up to 60 km, air-to-ground one-way communication maximum distance of 100 km; at the hight of 600 m, the PD—780 handheld space between the maximum distance of up to 30 km, airborne MD—780G vehicle and ground PD—780 handheld communication between the air-to-ground two-way communication distance,the maximum distance of up to 50 km, air-to-ground one-way communication up to 80 km, MD—780G vehicle space-to-ground communication, air-ground two-way communication distance up to 80 km, of the one-way communication up to 120 km. The results showed that the communication distance of ultrashort wave is related to the flight height and the radio station power. To establish an effective air defense system for aviation forest protection, it is necessary to build a certain number of terrestrial communication relay stations, unified equipment model and call frequency, and standard ultrashort wave radio noise reduction.
