Abstract: According to the status quo of forest fire barrier system in key forest areas in Lizhou, the current problems were analyzed such as single tree species, simple stand structure, complex outdoor fire source and low-density biological barrier zone. The countermeasures were put forward including desification of barrier network, and establishment of Forest Belts. At the same time, the network level of fireproof forest, tree species selection, structure and configuration of fireproof forest belts were explored. The fireproof forest zones were divided into two levels for building. The new fire prevention forest network zone was designed according to the local conditions and reasonable layout, by obviously mproving the density of the barrier network and the more even distribution of the obstructing network, so as to truly improve the comprehensive forest fire protection capability in Lizhou District, and reduce the hidden danger of forest fires.
