- Abstract
To explore the natural regeneration and its affecting factors of Fargesia robusta clone population, the main diet bamboo for giant panda, after Wenchuan Earthquake in 2008, an investigation was conducted on the growth and emergence of the bamboo shoots at three habitats with different intensities (strong, moderate, and null) of earthquake disturbance. In the moderately and undisturbed habitats, the basal diameter of the survived bamboo shoots was significantly greater, as compared with that in strongly disturbed habitat, and the height of the survived shoots decreased in the order of undisturbed > moderately disturbed > strongly disturbed habitat. No significant difference was observed in the density of new bamboo shoots among the three habitats, but the density of the survived bamboo shoots was significantly higher in the strongly and moderately disturbed habitats than in the undisturbed habitat, and the density of 1-and 2 years old bamboos showed a significant positive correlation with the density of dead bamboos. There existed significant positive correlations between the densities of new bamboo shoots, survived bamboo shoots, and 1-, 2-, and more years old bamboos, but significant negative correlations between the density of 1-and 2 years old bamboos and the coverage of gravels and slipping soils by Wenchuan Earthquake in 2008, and between the density of survived bamboo shoots and their canopy coverage.
