Abstract:

A growth cycle of moso bamboo (Phyllostachys edulis) stand is an important basis in management decision. In general, there is two years cycle of on-year or off-year phenomenon during moso bamboo stand growing. This study used a less disturbed moso bamboo stand in Tianmu Mountain National Nature Reserve of Zhejiang Province as a research object, one permanent plot of 100 m×100 m was established and divided into 100 units by adjacent grid inventory and has been annually surveyed for 5 years. The spectrum analysis of time series was applied to explore the growth cycle of moso bamboo stand. The results show that moso bamboo stand is uneven- aged forest, and its age diversity increases year after year from 1-14 year to 1-18 year during investigation. It was especially found that there is cycle diversity during the growth of moso bamboo stand. The cycle diversity includes two years cycle, three years cycle and six years cycle. Among the multiple cycles, two years cycle and six years cycle are significant. Therefore, the growth characteristics of multiple cycles, especially two years cycle and six years cycle, should be considered in moso bamboo stand management decision to take reasonable management measures to realize moso bamboo stand sustainable management.

Key words: Tianmu Mountain, Phyllostachys edulis stand, cycle, time series, spectrum analysis
