This paper deals with the techniques of astablishing fire prevention belts of fruit trees. The results thow that to devide the forests into blocks by building major and minor fire prevention trees belts among them and the fruit tree belts at the foot of the forests, thus forming a dosed fire prevention net work, is an Fruitful engineering easy to be put into practice, which can minimize the losses caused by the fir if any.

本文通过山区山脚田边果木防火林带营造技术的研究,结果表明:建立主、副防火林带和山脚田边果木防火林带,把森林分割切块,形成闭合的防火网络,是一种易推广、多效益的防火生物工程。能把山火造成损失降到最低限度。

The paper deals with the emergence,application and dissemination of the biologicalfire prevention,its developing trand show that the fire prevention belts on rather largescale are gradually forming the biological fire prevention system in south China forestareas. Biological engineering fire prevention is being performed,and has been broughinto the long-term plan of forestry construction. In the last decade,more and more ex-tensive and thorough quantitative studies of biological fire prevention have been conduct-ed in China and this has in turn promoted the development of the biological engineeringfire prevention technique. Biological fire prevention in China is in the forefront,and ithas gradually become a borderline subject,this in marker of the forest fire prevention inChina reaching a higher step. More and more research results on biological fire preven-tion will be achieved as the forest fire prevention in China moderninges.

中国生物防大的应运而生及推广应用的发展态势表明,南方林区具有相当规模的防火林带正逐步形成生物阻火体系。生物防火工程正在有规划地实施,并纳入林业建设的长远建设规划中。近十多年我国生物防火量化研究不断深入,领域逐步拓宽,生物防火研究的发展又推动生物工程防火技术的发展和创新。中国的生物防火己居世界前列,并正在形成一门边缘学科,这标志着我国森林消防工作登上新台阶。随着我国森林防火现代化的发展,生物防火研究必将会有更大的发展。

Through the study on growth,forest type structure,forest fuel weight and measuring of forest litter combustibility,the resutls showed: the growth of Alnus tinctoria is a fast,forest type structure has fire resistance for ground fire,weight of forest fuel is 1.19~1.46 kg/m 2 and not easily to burn. So it is suitable to build fire prevention belts in artificial coniferous forest.

辽东桤木(AlnustinctoriaSarg.)又名色赤杨,属桦木科(Betulaceae)赤杨属(Alnus)植物。该树种为15~20m高的乔木,分布于东北3省和山东省境内,生长于海拔200~1500m山地林中。具有耐瘠薄、萌蘖更新快等特点。其材...
