Study On The Fire PerTableance Of Biological Fire Belt

Forest is the "lungs of the earth", the safety of the forest resources and the stability of forest ecosystem, is related to human life increasingly fragile environment, and forest fire is one of the important disasters which damages forest resources security. It not only causes economic loss, the loss of tourism resources, cultural relics and the loss of the landscape by forest fires,the more important thing is the ecological environment resources damage and loss of life. Research the efficiency of biological fire prevention forest, the fire resistance to fire, economic development and ecological security has important value and significance.In nanchang city of jiangxi province, in the Wanli area We chose three biological fire prevention forest fire tree species(schima superba, camellia, michelia macclurei)to study the fire efficiency, investigated the fire the biology and ecology characteristics of tree species, We analyzed the different fire tree species in different seasons of different organs of determination of the physical and chemical properties, determination of the summer and winter forest microclimate, the different tree species composition of forest fire prevention perTableance test, fire prevention forest economic benefit, ecological benefit and social benefit by adopting the method of variance analysis and multiple comparison, determine the difference of three types of fire prevention forest zones of different tree species.Through research, preliminary conclusions as follows.(1)The average moisture content of different organs in spring, autumn and winter schima superba> michelia macclurei, the average ignition schima superba > michelia macclurei, the average calorific value differential> michelia macclurei>schima superba,the average crude ash schima superba > michelia macclurei,the average crude fat michelia macclurei > schima superba > schima superba,the average lignin differential > michelia macclurei, the average fiber Camellia > schima superba = michelia macclurei.(2)We concluded that forest zones of different wood species to improve the effect of microclimate, schima superba, second, the most obvious michelia macclurei is minimalby comprehensive comparison.(3) The three forest fire prevention are taken fire test at the same time, according to the situation of forest fire spread and flameout, schima superba fire effect is best, followed by camellia, michelia macclurei is the worst.(4)The annual net income of schima superba is 167 yuan/mu, camellia 1689 yuan/mu,michelia macclurei 300 yuan/mu. From the economic benefit analysis, the oil-tea's biological fire prevention benefit is best, followed by michelia macclurei, finally is schima superba.Comprehensive fire prevention forest belt the physical and chemical properties of different tree species, forest microclimate environment in cooling effect, the fire resistance perTableance and economic benefit indexes, such as fire prevention efficiency of schima superba > camellia > michelia macclurei.
