A method for afforestation of evergreen broad-leaved forests resistant to rain and snow freezing

Abstract

The invention relates to a rain snow and ice freezing resistance evergreen broad-leaf forest afforestation method, which belongs to the field of mountain forest ecological system environment protection. The method comprises the following concrete steps that major tree species and common tree species of coastal mountain typical evergreen broad-leaf forest are selected; through testing and analyzing the reflected response features of plants for resisting mechanical damage and low-temperature environment, a layer analysis method is used for calculating the wind and ice freezing resistance relative capability (IE value) of each species, and the suitable growth species are selected; the geomorphic growth preference features of the species are combined, the wind-resistance advance species applicable to different geographical conditions are screened; through the steps of afforestation, tending, function target tree culture and the like on the selected species, the vergreen broad-leaf forest with strong rain snow and ice freezing resistance capability can be integrally built. The method can be used for accurately selecting the rain snow and ice freezing resistance tree species applicable to different mountain environment. Compared with the conventional forest afforestation method, the method has the advantages that the freezing resistance performance of the afforestation tree species is good, the growth is good, the forest stand function targets are clear, the efficiency is high, and the like. The rain snow and ice freezing resistance evergreen broad-leaf forest afforestation method can be used for ecological restoration afforestation for rain snow and ice freezing mountain.

Description

technical field [0001] The invention belongs to the field of environmental protection of mountain forest ecosystems, and in particular relates to a method for afforestation of evergreen broad-leaved forests resistant to freezing by rain and snow Background technique [0002] The evergreen broad-leaved forest is the essence of my country's forest resources. It is a forest ecosystem with the most complex structure, the most stable community, the largest biomass, the richest biodiversity, and the strongest ecological function. The protection and development of evergreen broad-leaved forests not only has great strategic significance for maintaining national security, species security, climate security, freshwater security, and survival security, but also has far-reaching significance for the sustainable development of the Chinese nation. [0003] Rain and snow freezing can cause direct or indirect adverse effects on forests and regional ecological environment. For example, the m...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a kind of anti-freezing and mechanical damage resistance, good growth, and stand function in view of the current situation that the existing forestry technology lacks quantitative diagnosis of tree species' anti-freezing, rain and snow functional characteristics. A clear goal, safe and stable evergreen broad-leaved forest construction technology, to solve the technical bottleneck of the existing vegetation's weak ability to resist rain, snow and freezing disasters, including building a database of species resistance to rain and snow disasters, screening suitable species, species and the environment Optimized configuration, weeding and loosening soil tending, thinning, and later cultivation of target functional tree species, etc.
