摘要
本研究对汉江河岸恢复区环境特征进行了调查分析,并对表层土壤有机碳储量进行了量化。通过对21个调查点的调查分析,发现植物总数为17种,平均种数为2.86±0.13种/点。每个站点至少种植1种,最多种植7种。平均胸径9.1±0.6cm,平均胸高6.2±0.3m,土壤根含量0.13±0.18 g/ cm2。土壤特性分析结果显示,随着土层的加深,容重、固相比、碎石比、土壤硬度、含砂量、pH值等21项指标中有6项呈增加趋势。0 ~ 10cm表层土壤有机碳储量为11.54±1.08 t /ha, 10 ~ 20cm表层土壤有机碳储量为8.69±0.81 t /ha, 20 ~ 30cm表层土壤有机碳储量为7.97±0.79 t /ha, 0 ~ 30cm表层土壤有机碳储量为28.21±7.31 t /ha。不同土地利用方式的表层土壤有机碳储量以农用地最高,为35.17±5.31 t /ha,其次为居住区28.16±8.31t /ha、商业区21.87±9.05 t /ha、工业区19.23±12.48 t /ha、荒无区17.07±11.33 t /ha。表层土壤有机碳储量2006年最高,为38.46±3.14 t /ha, 2016年次之,为28.57±7.84 t /ha, 2011年为16.78±6.06 t /ha。研究结果有望为今后加强河岸带恢复立地的碳减排效果提供基础数据库和评价标准。
The Topsoil Characteristics, and Estimation of Topsoil Organic Carbon Storage at
Restoration Areas in Riparian Zones of the Han River
This study was carried out to investigate and analyze the environmental characteristics of restoration areas in the riparian zones of the Han River, and to quantify the amount of topsoil organic carbon storage. As a result of investigation and analysis of 21 survey sites, the total number of species planted was found to be 17, and the mean number of species was 2.86±0.13 species per site. At least one species and a maximum of 7 species were planted at each site. The mean diameter at breast height was 9.1±0.6cm, the mean height was 6.2±0.3m and the root content in soil was 0.13±0.18 g/cm 2 . As a result of the analysis of the soil characteristics, 6 out of 21 items, such as the bulk density, solid ratio, gravel ratio, soil hardness, sand content, and pH increased as the soil layer deepened. The topsoil organic carbon storage by layer was 11.54±1.08 ton/ha at 0-10cm, 8.69±0.81 ton/ha at 10-20cm, 7.97±0.79 ton/ha at 20-30cm, and the total from 0 to 30cm was 28.21±7.31 ton/ha. The highest amount of topsoil organic carbon storage by land use in the past was 35.17±5.31 ton/ha in agricultural lands, followed by 28.16±8.31ton/ha in residential areas, 21.87±9.05 ton/ha in commercial areas, 19.23±12.48 ton/ha in industrial areas, and 17.07±11.33 ton/ha in the barren areas. The highest amount of topsoil organic carbon storage in the restored areas was 38.46±3.14 ton/ha in 2006, followed by 28.57±7.84 ton/ha in 2016, and 16.78±6.06 ton/ha in 2011. The results of this study are expected to provide a basic database and evaluation criteria for enhancing the carbon abatement effects of the restoration sites in riparian zones in the future.
