精准计量城市绿地乔木碳汇量是提高绿地碳汇能力的前提。以平湖为例,采用单木调查结合绿地类型方法计量城区乔木碳汇,聚类分析树种碳汇能力,空间自相关与热力图分析碳密度、碳汇速率空间分布特征,以辅助城市绿地合理布局。结果表明:(1)...精准计量城市绿地乔木碳汇量是提高绿地碳汇能力的前提。以平湖为例,采用单木调查结合绿地类型方法计量城区乔木碳汇,聚类分析树种碳汇能力,空间自相关与热力图分析碳密度、碳汇速率空间分布特征,以辅助城市绿地合理布局。结果表明:(1)平湖的附属绿地碳密度与碳汇速率最大,城市乔木绿地平均乔木碳密度(22.72 t C/hm^(2))为中上水平,平均乔木碳汇速率(8.99 t CO_(2)e a^(-1)hm^(-2))高于非城市森林;(2)硬阔Ⅱ((31.13±15.11)kg CO_(2)e/a)与硬阔Ⅰ((30.43±17.56)kg CO_(2)e/a)树种碳汇能力强于松类、软阔、杉类、柏类;(3)城市乔木绿地乔木碳密度和碳汇密度具有空间聚集性,高值常沿道路呈条带状或沿水域呈团块状分布。研究方法和结论对于厘清城市绿地乔木的碳家底,管理和提升城市自然碳汇功能,促进城市碳中和具有重要的理论和实践意义。展开更多
采用野外调查和室内分析相结合的方法，对武夷山市5种主要土壤类型（黄壤、红壤、潮砂土、高山草甸土、紫色土）茶园的土壤团聚体组成及其稳定性特征进行了研究。结果表明：茶园土壤大团聚体含量均随土层加深呈减少的趋势，微团聚体含...采用野外调查和室内分析相结合的方法，对武夷山市5种主要土壤类型（黄壤、红壤、潮砂土、高山草甸土、紫色土）茶园的土壤团聚体组成及其稳定性特征进行了研究。结果表明：茶园土壤大团聚体含量均随土层加深呈减少的趋势，微团聚体含量则相应上升。黄壤、高山草甸土、紫色土〉5 mm 的大团聚体含量最高，所占比例在18.07%～89.23%；红壤和潮砂土土壤团聚体含量则以〉0.25 mm 微团聚体含量最高，所占比例为37.16%～63.91%。茶园土壤R0.25（〉0.25 mm水稳性团聚体）含量在36.08%～97.23%之间（均值为73.60%）；高山草甸土平均质量直径（MWD）和几何平均值（GMD）均显著高于其他土壤类型，黄壤和紫色土次之，潮砂土最低，分形维数（D）的变化趋势则相反。相关分析表明，土壤团聚体组成及稳定性指标与土壤有机碳、全氮、全磷、容重、孔隙度、砂砾、粉粒有显著相关性，与土壤C/N、全钾、pH、粘粒的相关性不明显。展开更多
