鲁西黄泛平原不同林龄杨树人工林碳储量分布格局及影响因素分析
Ecosystem Carbon Storage Distribution and Influencing Factors in Different-aged Poplar Plantations in the Yellow River Floodplain in Western Shandong,China
摘要
Abstract
To reveal the carbon fixation mechanism of poplar plantations with different ages and to investigate the relationship between carbon storage and environmental factors in the Yellow River Floodplain,the distribution patterns and influencing factors of carbon storage in the tree layer,herb layer,litter layer,and soil layer of grassland(CK)and four distinct-aged(10,30,40,50 a)poplar plantations in the Yellow River Floodplain were examined by field surveys and indoor analysis,respectively.The results showed that the proportion of biomass in the herb layer of the poplar plantation decreased gradually,and the proportion of biomass in the tree and litter layers progressively increased with the increase of stand age.The ratio of biomass in the tree layer to total biomass was the highest(93.21%to 96.17%),followed by the litter layer(3.99%to 3.20%),and in the herb layer was the lowest(2.84%to 0.63%).The average carbon content of the poplar plantations was the highest in tree layer of 50-a plantation(420.40 g⋅kg-1),in herb layer of 10-a plantation(365.86 g⋅kg-1),and in litter layer of 30-a plantation(398.67 g⋅kg-1)and the average carbon content of soil layer increased significantly with the increase of stand age.The carbon storage of poplar plantation increased with age,and the distribution pattern was tree layer(975.81 t⋅hm-2)>soil layer(275.06 t⋅hm-2)>litter layer(38.01 t⋅hm-2)>herb layer(19.19 t⋅hm-2),the soil layer and tree layer were the main components of carbon storage of poplar plantation,accounted for 95.31%to 97.46%of the total carbon storage.Correlation and redundancy analysis showed that tree height(H),soil organic matter(SOM),diameter at breast height(DBH),and stand density(SD)were the main environmental factors influencing carbon storage in poplar plantations.The results can provide a theoretical basis and data support for the carbon sink function of poplar plantation forests and the management strategy of plantation forests in the Yellow River Floodplain.关键词
