Problems solved by technology

However, the results of long-term field studies have found that whether it is due to natural factors or human disturbance, the secondary bamboo-shrub forest land can be restored to the original forest community structure through natural succession. It is completely impossible and cannot meet the growing population of wild giant pandas' demand for habitat quality and area. However, if artificial restoration and transformation measures are implemented, the forest community structure and habitat quality can be restored quickly to achieve a suitable habitat for giant pandas. local standard

Embodiment 1

[0047] Implementation location: in the subalpine secondary bamboo-shrub jungle at Niba Mountain, Daxiangling Provincial Nature Reserve, at an altitude of 2100m. The dwarf bamboo under the forest is March bamboo.

[0048] 1. Forest land clearing: land preparation will be carried out after the snowfall decreases in March. The sub-alpine secondary March bamboo-shrub forest was selected as the restoration site. The canopy canopy density of the restoration site is 8%, and the bamboo density in March is 28 plants / m 2 (conform to the standard of more than 1.5 times of the original forest), and the bamboo cover is 90%.

[0049] The forest belts will be cleared in the form of horizontal mountain bands and along the contour lines. The specific operation method is: along the contour line, follow the method of "cut 3m and leave 2m" for directional thinning, the directional thinning bandwidth is 3m, and the reserved bandwidth is 2m. When preparing the site, clear the Sanyue bamboo in th...

Abstract

The invention discloses a method for recovering a suitable habitat of pandas in a sub-alpine secondary bamboo shrub forest land, and belongs to the technical field of degraded sub-alpine forest community structure recovery. The method comprises directional thinning transformation and indigenous macrophanerophytes species introduction. The method comprises the following steps of: firstly, investigating the plant community characteristic data of the secondary bamboo shrub forest land; secondly, according to canopy cover degree data, dwarf bamboo density data and bamboo cover degree data, determining a recovery and transformation land; thirdly, according to a method of "cutting 3m and reserving 2m", carrying out directional thinning cutting on dwarf bamboos in a 3m forest belt and shrubs influencing the growth of upper-layer forest trees along a height line; and finally, introducing indigenous arbor species into the 3m forest belt. The technical blank of panda habitat vegetation recovery and conservation in a current degraded secondary bamboo shrub forest land recovery process is made up, the quality of the sub-alpine secondary bamboo shrub forest land habitat is rapidly improved by taking directional thinning transformation and indigenous arbor species configuration as a core in the panda habitat, and the problems of a long recovery period and a poor recovery effect when the secondary bamboo shrub forest land is subjected to hillside closing to facilitate afforestation are solved.

Description

technical field [0001] The invention relates to the technical field of restoration of degraded subalpine forest community structure, and more specifically relates to a method for restoring a suitable habitat for giant pandas in subalpine secondary bamboo-shrub forest land. Background technique [0002] Subalpine coniferous forest is an important forest type in the habitat of giant pandas, with an altitude between 2200 and 4200m. Its structure and dynamics affect the survival and reproduction of giant pandas. Around the 1970s, due to the needs of national construction and local economic development, the original subalpine coniferous forests in this area, with fir (Abies fabri) and hemlock (Tsuga chinensis) as the main dominant tree species, were logged on a large scale. In some clear-cutting lands, dwarf bamboos rapidly proliferate and occupy the understory habitat, forming a dense bamboo shrub layer, which seriously restricts the regeneration of arbor species in subalpine co...
