Abstract

The invention discloses a mountainous area artificial forest tending management method based on soil moisture, and relates to the technical field of forestry. The method comprises the following steps: taking artificial forests with different recovery stages, different configurations and different site conditions as samples; obtaining community composition change rules in the artificial forest recovery process by means of sampling analysis; obtaining an ecological hydrological mechanism of soil moisture deficit in the artificial forest development process through the community composition change rules; and according to the ecological hydrological mechanism of soil moisture deficit, obtaining an intermediate cutting intensity threshold value for relieving soil moisture drought. According to the method, tending management in the restoration process of artificial vegetation in mountain land in arid regions is carried out, the stability of a mountain land artificial forest ecological system is enhanced, the problems of drought deep soil, poor growth condition, serious degradation, large-area death and the like in the restoration process of artificial vegetation in the mountain land of the arid regions are solved, and ecological civilization construction and economic sustainable development of the mountain land in the arid regions are promoted.

Description

technical field [0001] The invention relates to the technical field of forestry, in particular to a method for tending and managing artificial forests in mountainous areas based on soil moisture. Background technique [0002] At present, my country is the country with the largest planted forest area in the world, and its development speed is 5.7 times the global average level. Artificial forests play an important role in my country's ecological civilization construction and economic development. Since the implementation of several projects such as the Natural Protection Project and the Returning Farmland to Forest (Grass) Project in the Qilian Mountains area, the area of ​​artificial vegetation in this area has increased significantly. However, due to the lack of scientific theoretical guidance and sustainable management technology for a long time, the plantation system in this area also has problems such as soil drought, biodiversity reduction, and poor system stability.
