Comparing Simulated Carbon Budget of a Lei Bamboo Forest with Flux Tower Data

Abstract

Bamboo forest ecosystem is the part of the forest ecosystem. The distribution area of bamboo forest is limited, but in somewhere, like south China, it has been cultivate for a long time with human management. As the climate change has been take great effect on forest carbon budget, many researchers pay attention to the carbon budget in bamboo forest. Moreover cultivative management had a significant impact on the bamboo forest carbon budget. In this study, we modified a terrestrial ecosystem model named Integrated Biosphere Simulator (IBIS) according the management of Lei bamboo forest. Some management, like fertilization, shoots harvesting and organic mulching in winter, had been incorporated into model. Then we had compared model results with the observation data from a Lei bamboo flux tower. The simulated and observed results had achieved good consistency. Our simulated Lei bamboo forest yearly net ecosystem productivity (NEP) was 0.41 kgC a -1 of carbon, which is very close to the observation data 0.45 kgC a -1 of carbon. And the monthly simulated results can take the change of carbon budget in each month, similar to the data we got from flux tower. It reflects that the modified IBIS model can characterize the growth of bamboo forest and perform the simulation well. And then two groups of simulations were set to evaluate effects of cultivative managements on Lei bamboo forests carbon budget. And results showed that both fertilization and organic mulching had taken positive effects on Lei bamboo forests carbon sequestration.

Soil respiration of a Moso bamboo forest significantly affected by gross ecosystem productivity and leaf area index in an extreme drought event

“…Bamboo forests are widely distributed in warm temperate, subtropical and tropical zones between 46°N–47°S ( Lu et al, 2014 ). Globally, bamboo forests cover 31.5 million ha ( FAO, 2010 ).…”

Bamboo as a Nature-Based Solution (NbS) for Climate Change Mitigation: Biomass, Products, and Carbon Credits

“…In Assam, India, the NEP for different species, ages, and village physiography ranged from 0.20 to 0.74 kg CO 2 /m 2 /yr [53]. Other tools, including carbon flux measurements [48] and the triple-flux model [52], also demonstrated the great NEP potential of bamboo forests. The estimation of bamboo forest biomass carbon storage for a diverse grouping of regions and species worldwide was comprehensively studied.…”

Effects of Different Management Measures on Carbon Stocks and Soil Carbon Stocks in Moso Bamboo Forests: Meta-Analysis and Control Experiment

“…Moso bamboo (Phyllostachys heterocycla) constitutes a vital forest resource in southern China, with a bamboo coverage exceeding 6.01 million hectares, representing 74% of the total bamboo forest area in China [11]. The investigation into the carbon sequestration and sink enhancement potentials of bamboo forest ecosystems holds considerable scientific significance [12,13]. Moso bamboo exhibits a broad and extensive distribution range, characterized by a rapid growth rate that enables alternating-year harvests and perpetual utilization [14].…”
