Temporal Change in Aboveground Culms Carbon Stocks in the Moso Bamboo Forests and Its Driving Factors in Zhejiang Province, China

Abstract

Moso bamboo (Phyllostachys pubescens) has high carbon sequestration potential and plays an important role in terrestrial carbon cycling. Quantifying the temporal change in Moso bamboo forest carbon stocks is important for understanding forest dynamics and global climate change feedback capacity. In 2009, 168 Moso bamboo forest sample plots were established in Zhejiang Province using National Forest Continuous Inventory protocols and enhanced measurements. These plots were revisited and remeasured in 2014. By comparing the two years, culms number in age classes 2 and 4 increased by 12.3% and 82.5%, respectively, while that in age classes 1 and 3 decreased by 14.7% and 0.03%, respectively. The total aboveground culms carbon stocks increased by 2.95 Mg C ha −1 in the sample plots. On average, age classes 2 and 4 contributed 25.5% and 86.7% of the change in total carbon stocks, respectively. The carbon sequestrated by aboveground culms was 0.42 Tg C year −1 , accounting for 1.55 Tg CO 2 year −1 in Moso bamboo over an area of 0.78 million hectares in Zhejiang Province. The change in Moso bamboo carbon stocks did not correlate with environmental factors, but significantly increased with increasing culms number and average diameter at breast height (DBH). Our study helps contribute to improvements in Moso bamboo forest management strategies and promote carbon sequestration capacity.

Leaf-Associated Shifts in Bacterial and Fungal Communities in Response to Chicken Rearing Under Moso Bamboo Forests in Subtropical China

“…The shoot of moso bamboo can grow from 0-20 m in 45-60 days under suitable spring conditions [3]. Moso bamboo plays an important role in ecological and environmental protection [4,5], as well as in rural economic development in China [6,7]. Bamboo belongs to the subfamily Bambusoideae in the family Gramineae, which includes approximately 1500 species from approximately 90 genera worldwide [1].…”

Allometric Equations for Predicting Culm Surface Area of Three Bamboo Species (Phyllostachys spp.)

“…Many studies in the past decade have shown the potential of bamboo forests as a carbon sink (a process that removes carbon dioxide from the atmosphere) [6][7][8][9][10][11]. Nevertheless, there remains considerable debate whether bamboo forest ecosystems are a carbon sink or a carbon source (a process of releasing carbon dioxide to atmosphere) [12][13][14].…”

“…Numerous equations have also been derived for estimating culm biomass or volume of bamboo species [11,[32][33][34][35][36][37][38], but only one study has investigated how S is related to other culm dimensions [39]. In Phyllostachys pubescens Mazel ex Houz., a common bamboo species in Asia with high potential for carbon sequestration [6,9,10,40], a power equation described the relationship between S and external culm diameter at breast height (D) [39]. In addition, a linear equation was suitable for representing the relationship between S and the product of D times total culm length (H) [39].…”

Tissue-cultured regeneration and ecological values in major bamboo species

“…The carbon assimilation of 9.89 mg/ha/year above-ground part was trapped by the Phyllostachys maikinoi (Wang and Chen 2015). The carbon sequestration of 5.1 mg/ha/year by the aboveground parts (culms, branches, leaves) and 1.9 mg/ha/year by the below-ground parts were assimilated by Acidosasa edulis in China (Xu et al 2017a). Similarly, 23.7 mg/ha/ year by above-ground parts and 10.9 mg/ha/year by below-ground parts were reported in Arundinaria fargessi (Hinge et al 2018).…”
