A natural-like construction method of Chinese fir and Phoebe mixed forest

Abstract

The invention discloses a natural imitation method for constructing a mixed forest of fir and phoenix, which adopts artificial means to construct a mixed forest of Chinese fir and phoenix similar to the distribution pattern of fir in a natural forest. The method includes the mixed forest of Chinese fir and phoenix The determination of the mixed cross ratio area and the young forest tending operation; the method of the present invention not only has the advantages of simple afforestation technology, but also carries out afforestation by imitating the natural mixed method, and also has the advantages of high survival rate of afforestation, excellent stand growth performance, and can effectively meet the requirements of existing conditions. Production demand, but also has high economic and ecological benefits, has broad 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.
