海拔1600~3000m的针叶林区是云南省森林火灾多发区,每年森林火灾发生次数占全省的85%左右。通过调查62块典型样地,根据可燃物的配置结构,应用植物群落划分法,基于森林亚类型,从森林可燃物的角度,以主要伴生树种或下层植被为基础,结合自然条件与林分结构特点把云南主要针叶林可燃物类型划分为6个类型,即灌木-云南松林,草类-云南松林;灌木-思茅松,草类-思茅松;灌木-华山松,草类-华山松。
The coniferous forest area of 1600 ~ 3000m above sea level is a frequent forest fire in Yunnan Province, accounting for about 85% of the total number of forest fires every year. Based on the disposition of combustibles, the classification of plant communities and the sub-types of forest, based on the analysis of combustible materials in forests, the main contigs or sub-vegetation types, we combined the natural conditions with stand structure Characteristics The types of combustible materials in Yunnan’s main coniferous forests are divided into six types, namely shrubs-Yunnan pine forests, grass-yunnan pine forests; shrubs-Simao pine, grass-cedar pine; shrub-huashan pine-grass-huashan pine.
