Ecological construction method of modified and cultivated fireproof forest belt barrier system

The invention belongs to the field of fireproof forest belt construction, and provides a modified fireproof forest belt barrier system ecological construction method which comprises the following steps: S1, constructing a modified fireproof forest belt barrier system structure module; s2, forest belt cleaning is carried out in a forest land suitable section where the modified fire forest belt is planned and constructed, and dead standing trees, fallen trees, part of branches, small arbors, shrubs, weeds, excessive litters and other combustible materials are removed; s3, fire-resistant herbaceous plants are planted in the suitable woodland section of the recultivated fire forest belt, a plant configuration mode is constructed and optimized, and an ecological maintenance-free mode is formed; through screening of under-forest suitable fire-resistant herbaceous plants and the ecological maintenance-free technology of the modified fire-proof forest belt blocking system, green coverage is ensured to be formed in th
