    Abstract:

    In November 2017, we designed 5 treatments under different strip clearcutting in Moso bamboo forests in Huangshan District of Anhui Province, including the contrast (CK), 3 m logging strip (D1), 6 m logging strip (D2), 9 m logging strip (D3) and 12 m logging strip (D4). We investigated several indexes of spring shoot and new bamboo in 2018, mainly including the number of spring shoot and new bamboo, the diameter of breast height (DBH) of new bamboo and the biomass of new bamboo. We discussed the effects of different strip clearcutting measures on Moso bamboo forest restoration in order to provide a theoretical basis for scientific and reasonable logging widths of strip clearcutting of Moso bamboo forests. (1) The number of spring shoot per hectare in four logging treatments was larger than that of CK, and it increased with the increase of logging intensity. The number and rate of degraded shoot per hectare in treatments with higher intensity (9 m and 12 m logging strips) was lower than that of treatments with lower intensity (3 m and 6 m logging strips) and CK. (2) The mean DBH of new bamboo in four logging treatments were lower than that of CK, and the mean DBH of new bamboo in treatments with higher intensity (9 m and 12 m logging strips) was significantly lower than that of mother bamboo, and it was negatively correlated with logging strip margin. The proportions of new bamboo with small and medium DBH were increased in treatments with higher intensity (9 m and 12 m logging strips). (3) The biomass of aboveground per hectare of new bamboo in four logging treatments were lower than that of CK, following the order of CK, D3, D4, D2, and D1, respectively. There are different responses to different strip clearcutting measures on qualitative characteristics in Moso bamboo forests. In conclusion, the recovery ability of spring shoot and new bamboo in 6-9 m logging strips is better. However, the recovery of Moso bamboo forest after strip clearcutting is a periodic process, and it is necessary to consider the longterm effects of different logging intensity on the quality of new bamboo.
