A preliminary analysis is conducted on the fragmentation of the habitat of giant panda cause by forest management to provide scientific basis for the regeneration of the habitat of gaint panda and the promotion of the benefits of natural forest protection.
③Modern ecological means should be taken to protect the original Metasequoia population and their habitant environment, and research on Metasequoia vegetation restoration and reconstruction should be carried out. Restoration and reconstruction should be put into practice in the Xiaohe Valley, the concentrating distribution.
The biotope landscape refers to protecting the existing habitat for animals and plants, restoring the natural environment that was destroyed, and creating new biology environment to life.
Post-fire habitat restoration of sables during winter season in northern slope of the Great Xing'an Mountains
This study examined the impact of wetland habitat loss and isolation on an insect-plant interaction, and the subsequent rate of recovery of the interaction following experimental habitat restoration.
Subsequently, to test whether the interaction can recover following habitat restoration, we surveyed herbivore colonisation rates and herbivory damage on naturally regenerated S.
Habitat restoration, such as the relaying of mussel shells from the mussel industry, is another important management tool that should be included in an ecosystem management approach of the mussel fishery.
We evaluated 33 canals backfilled through July 1984 to assess the success of habitat restoration.
The indicator system for describing the degradation of giant panda's habitat is developed, including three kinds of indicators as topography, forest community and feeding bamboo. The topographic indicators include altitude, slope grade, aspect etc. Height of trees and shrubs, density of trees and shrubs, shrub species, shrub coverage, tree composition and canopy are employed to evaluate the forest community. The quality of the feeding bamboo is assessed by the density and height of bamboo, bamboo trunk base...
The indicator system for describing the degradation of giant panda's habitat is developed, including three kinds of indicators as topography, forest community and feeding bamboo. The topographic indicators include altitude, slope grade, aspect etc. Height of trees and shrubs, density of trees and shrubs, shrub species, shrub coverage, tree composition and canopy are employed to evaluate the forest community. The quality of the feeding bamboo is assessed by the density and height of bamboo, bamboo trunk base diameter and the percentage of young bamboos. In brief, the standards for the restoration of the habitat of giant panda are as following: altitude between 2 600～3 000 m, slope grade between 25°～45°, tree height<15 m, shrub height<2 m, shrub density >5 000 individuals/hm 2, tree density<300 individuals/hm 2, number of shrub species> 5, percentage of Abies and Picea in forest composition>50%, shrub coverage between 80%～100%, canopy<50%, bamboo density between 35～102 individuals/m 2, bamboo base diameter>4 4mm, percentage of young bamboos in all bamboos>25%, bamboo height between 1 8～2 8 m.At the end, restoration, reallocation and rehabilitation as three approaches are proposed for the restoration of giant panda's habitats.
Reported the result of Golden monkey surveyed in Changqing Nature Reserve in June 2001, which surveys conducted by interview with local people, historical monitoring data and site quantity and distribution surveying. The result showed that there are 20 groups of Golden monkey, the total number is 470～630, and density is about 5.88～7.88/km~2, and the distribution area is 80KM2, The key habitat is natural forest, or remain forest after part logging and natural regenerative forest patches. The plantation forest,...

The result showed that there are 20 groups of Golden monkey, the total number is 470～630, and density is about 5.88～7.88/km~2, and the distribution area is 80KM2, The key habitat is natural forest, or remain forest after part logging and natural regenerative forest patches. The plantation forest, shrub and clear logging area, sparse woodland and other wilderness patches hindered the habitat use and constrained movement. So the Golden monkey population in the reserve is in the stage of restoration. The crucial task for the Golden monkey management is to conduct habitat restoration and regeneration.
The main activities of forest management in Longcaoping have disturbed the habitat of giant panda occurring in Qinling Mountains. In the late 1980s especially, the activities of forest management such as cutting and regeneration increased with great frequency due to the drive of marked economy resulting the fragmentation of the habitat of giant panda, and leading to the-fact that no giant panda was found during the second nationally general investigation. Giant pandas have been found however after the overall...
The main activities of forest management in Longcaoping have disturbed the habitat of giant panda occurring in Qinling Mountains. In the late 1980s especially, the activities of forest management such as cutting and regeneration increased with great frequency due to the drive of marked economy resulting the fragmentation of the habitat of giant panda, and leading to the-fact that no giant panda was found during the second nationally general investigation. Giant pandas have been found however after the overall suspending of cutting in the area adjacent to the national nature reserve of Longcaoping. A preliminary analysis is conducted on the fragmentation of the habitat of giant panda cause by forest management to provide scientific basis for the regeneration of the habitat of gaint panda and the promotion of the benefits of natural forest protection.
