民勤新能源风电场典型植物土壤碳密度估算及其空间分布特征
Estimation of soil carbon density and spatial distribution characteristics of typical plants at the Minqin new energy wind farm
摘要
Abstract
To investigate the patterns of vegetation and soil carbon density distribution in large-scale new ener-gy wind farms and their influencing factors,as well as to uncover the driving mechanisms by which wind farm oper-ations affect the local ecosystem carbon cycle,this study conducted vegetation and soil surveys and sampling across 45 plots within five distinct monitoring areas(upwind,center,downwind,edge,and external control)of the Min-qin Hongshagang New Energy Wind Farm.Based on carbon content measurements from the samples,the impact of wind farm operations on biomass accumulation of typical plant communities and soil carbon density distribution in different monitoring areas was estimated.The results showed:(1)Wind farm operations significantly altered the structure of regional plant communities,thereby increasing the variability in plant carbon density across different monitoring areas.The average plant carbon density in the external control area was about 1.63 t·hm-2,while the average within the various internal areas of the wind farm was about 0.69 t·hm-2.(2)The impact of wind farm op-erations on soil organic carbon density was not significant,with all monitoring areas maintaining similar levels,and the average soil organic carbon density overall remained between 21.45 and 29.67 t·hm-2.(3)Using a soil depth of 40 cm as a node,the vertical distribution of soil organic carbon density in the 0～100 cm range of different moni-toring areas generally showed an increase with depth in shallow soils(<40 cm)and a fluctuating decrease followed by an increase in deeper soils(>40 cm).(4)Total plant biomass is a key factor affecting both plant carbon densi-ty and soil organic carbon content in the study area.The findings are expected to provide a scientific foundation for the efficient operation of new energy wind farms in arid regions,contribute to addressing global climate change,and support national ecological security decisions.关键词
