林业生产的根本内容:一是培育森林;二是利用森林。然而,有相当数量的森林毁于火灾。所以认真落实“预防为主、积极消灭”的方针,做好森林保护、减免森林火灾,对于我们少林国家具有重要意义。一、桃山林区存在易燃植被和火险性气候条件森林火灾只有在适当的自然条件下才能发生。影响森林燃烧的自然因素是植被和气候条件。桃山林区植物种类较多,山地、河谷平地及沟塘沼泽布满了各种乔、灌木及草本植物。天然林多属成、过熟林,基本是几经采伐的过伐林,已由原来的阔叶红松林逆行演替为现在的针阔混交林、阔叶混交林、杂木林。林地杂草、灌木丛生,采伐剩余物积累 The basic content of forestry production: First, cultivate the forest; the second is to use the forest. However, a considerable number of forests were destroyed by fire. So earnestly implementing the principle of “prevention first and actively eliminating it”, doing a good job in forest protection and reducing or eliminating forest fires is of great significance to our country. I. There are flammable vegetation and peat-borne climatic conditions in the Taoyuan forest area. Forest fires can only occur under appropriate natural conditions. Natural factors that affect forest burning are vegetation and climatic conditions. There are more plant species in the forest area of ​​Taoshan, and the mountainous, valleys and gully swamps are covered with various kinds of trees, shrubs and herbs. Most of the natural forests are mature and over-mature forests, which are basically over-cut forests that have been harvested. The retrograde succession of the original broad-leaved Korean pine forests is now dominated by mixed coniferous and broad-leaved mixed forests and mixed woods. Woodland weeds, shrubs, harvest residues accumulated
