Method for constructing nature-imitated fir and fire-power hybrid forest

Abstract

The invention discloses a method for constructing a nature-imitated fir and fire-power hybrid forest. The fir and fire-power hybrid forest similar to fir in distribution pattern in a natural forest isconstructed by adopting an artificial way. The method comprises the steps of determining the hybrid proportion area of the fir and fire-power hybrid forest and tending young forests. The method disclosed by the invention has the advantages that the afforestation technology is simple, afforestation is performed by adopting a nature-imitated hybrid mode, the afforestation survival rate is high, thestand growth performance is excellent, and the production requirements under the existing conditions can be effectively met; and meanwhile, the method has high economic benefits and ecological benefits and wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of forest management, and in particular relates to a method for constructing a natural imitation fir and firewood mixed forest. Background technique [0002] Fujian Province is a key collective forest area in the south of the country, and it is also an important ecological barrier in the south of my country. The mountains and forests are a major feature and advantage of Fujian. According to the eighth national forest resource inventory report, the forest area of ​​Fujian Province is 8.0127 million hm 2 , the forest coverage rate is 65.95%; the forest volume reaches 607.9615 million m 3 , of which 248.5323 million m of artificial forest stock 3 . Among the timber tree species used in Fujian plantation forests, due to the influence of Pine xylophilus in recent years, Chinese fir has become the most important fast-growing timber tree species, accounting for about 46% of the total area of ​​plantation forests...

AI Technical Summary

Problems solved by technology

However, due to the fact that the traditional mixed model ignores the difference in growth rate between tree species and many problems in afforestation density and forest management, the mixed effect of fir and broad-leaved mixed forest is not good, and the expected purpose cannot be achieved.

[0005] In view of the unsatisfactory effect of the traditional Chinese fir and broad-leaved mixed forest, the inventor found in the early investigation of the Chinese fir natural forest community: In the natural forest, the Chinese fir is distributed in clusters, and the Chinese fir grows among the broad-leaved trees.
