Method for recovering cold temperate zone forest wetland vegetation after extremely severe fire

Abstract

The invention relates to a method for recovering cold temperate zone forest wetland vegetation after extremely severe fire. The method mainly comprises the steps of recovery border determination, field cleaning, tree species selection, seedling planting configuration, soil preparation, seedling planting, tending management and the like. The method for recovering the cold temperate zone forest wetland vegetation after the extremely severe fire aims at solving the problems that spontaneous recovery time is long and retrogressive succession is caused after cold temperate zone ecologically vulnerable area forest wetland severe degeneration, and can recover the vegetation as soon as possible, build an optimized wetland vegetation community structure, effectively improve stability and self maintenance of the degenerated forest wetland, achieve positive succession development, and rapidly recover ecosystem functions.

Description

technical field [0001] The invention relates to a method for restoring forest wetland vegetation in a cold temperate zone after being subjected to extremely severe fires, and belongs to the technical field of ecological construction, in particular to a method for restoring forest wetland vegetation in a cold temperate zone after extremely severe fires. Background technique [0002] At present, post-fire vegetation restoration is a hot spot and key issue in fire ecology research all over the world. Research in this field started relatively late in my country. Research on post-fire vegetation restoration mostly focuses on forest and grassland ecosystems. There are few studies on vegetation restoration of post-fire wetland ecosystems. Research on wetland ecosystems in cold temperate zones is even weaker. The research is scattered and lacks systematization, and the research content is mostly related to post-fire nutrient cycle, post-fire soil physical and chemical properties chan...

Problems solved by technology

Research in this field started relatively late in my country. Research on post-fire vegetation restoration mostly focuses on forest and grassland ecosystems. There are few studies on vegetation restoration of post-fire wetland ecosystems. Research on wetland ecosystems in cold temperate zones is even weaker. The research is scattered and lacks systematization, and the research content is mostly related to post-fire nutrient cycle, post-fire soil physical and chemical properties changes, post-fire plant community characteristics changes and vegetation succession process, etc., and the factors affecting post-fire wetland vegetation restoration are less The research on the theory and technology of forest wetland restoration in the cold temperate zone after severe and extremely severe fires is even more lacking.

[0003] my country's cold temperate forest wetland forests are mainly distributed in the Greater Khingan Mountains, which play an important role in maintaining regional ecological balance. The ecosystem is very fragile. Severe and very severe fires will lead to significant degradation of the ecological functions of forest wetlands. It will not only take a long time for vegetation recovery after the fire , and there is great uncertainty in the succession process, and even reverse succession will never recover
