According to forest economic benefit, the maximum allowable density mathematical model of fire belt network was established by accurate calculation for feasibility evaluation of fire belt density in artificial forest, which provide a basis for the construction of fire belt network.
STUDIES ON THE EFFECT OF FOREST GROWTH AND SOIL PRODUCTIVITY MAINTAINING AFTER BUILDING THE FIRE PREVENTION FOREST BELT OF Mytilaria laosensis ON THE ORIGINAL RAW-SOIL FIRE PREVENTION ROAD
Compare to the original raw-soil fire prevention road,the fire prevention forest belt not only improving amount and buildup of soil microbe and soil enzymatic active and physical and chemical soil properties,boosting up the function of waterhead self-restraint,but also posses notable economic benefit.
To build biological fire break forest belt is an effective method for preventing the forest fire from spreading and for reducing economic lose. And,scientificly selecting fire break tree species and rationally deciding forest belt density is critical to build biological fire break forest belt.
Stand growth,fire break effect,increase soil fertility,conserve water and increase economy effect of Michelia macclurei fire break forest belt were studied on saw soil fire break road. The study results showed that Michelia macclurei has the better adaptability,it's a fast growing and has the better fire control property,it is average tree height and DHB at the ages of 12were 9.58m and 9.07cm,and biomass was 39.62t.
