Ustification of the construction of a fire barrier for artificial pine forests of the Irtysh region (on the example of Kazakhstan)

Priirtishja striped piny stands are represented chiefly by pure pine stands and are characterized by very high actual burning index. Forest cultures formed by striped method are especially dangerous as concerns fire occuzend. When forming these forest culteres2 year-oldpeanlets of penussievestris planting has been carried on in raws from north to south direction according the scheme 1,5 ´ 0,5 m. Every 5 raws of forest cultures have been separated from the neighbouring ones that have been planted by analogous scheme by a stripe of 6 m in width. Planting have not been carried ont on these stripes. They served for moisture accumulation and combined with fire linteslayed out along them played part of fire barriers. Fostop the latter a compartment of 1000x1000 m in sixe is recommended to divide in Ysquare plots with total square 25 ha each with antifirebranes 8 m in vidth. We offered the article deals the variant of antifire barrier in artificial betted piny stands of Rriirtyshhya formed by striped method that makes possible to minimize the amount of work necessary to form it and quarantee effective fire suppression...
