Abstract:
为提高碳储量估算精度，探讨土壤有机碳空间异质性对黄山松更新苗的影响，采用地统计学方法分析土壤有机碳的空间变异特征与格局.结果表明：戴云山黄山松林ⅰ层（0-20cm）、ⅱ层（20-40cm）和全剖面的变异系数分别为45.69%、65.82%和47.73%，均属于中等变异；最佳理论模型依次为指数模型、球状模型和高斯模型；均具有强烈空间自相关性，由结构性因素引起的空间异质性比例分别为11.03%、0.20%和12.90%；有效变程分别为18.60m、18.10m和14.55m.黄山松林土壤有机碳密度各向异性明显，空间自相关范围（moran’si）总体随空间距离增加而呈减弱趋势；分形维数值：全剖面（1.940）＞ⅰ层（1.927）＞ⅱ层（1.917），与半方差函数块基比参数反映的规律相一致.从空间分布特征看，黄山松林ⅰ层、ⅱ层和全剖面土壤有机碳密度均呈明显的带状和斑块状镶嵌分布，且斑块的形状、大小差异显著.黄山松更新苗主要分布于特定土壤有机碳密度斑块中，而在最大值和最小值斑块中分布极少.因此，对黄山松林进行近自然林经营时，应考虑其土壤有机碳的丰缺情况以及空间异质性对黄山松更新苗的制约作用.图3表3参20
