摘    要:立足样品测试数据,利用空间分析、空间插值、地质统计以及景观生态学方法,深入分析了深圳大鹏湾表层沉积物碎屑矿物的空间分布特征,并使用球状模型对相应半变异函数进行理论建模。结果表明,碎屑矿物分布的Hurst分维数为0.28~0.97,空间几何分维数为1.03~1.72;Moran Ⅰ型空间自相关系数-0.15~0.53。在此基础上,以等值线分布所包围范围作为划分尺度,以Shannon-Wiener信息指数作为度量,得到的矿物分布所反映出的信息量或者富集程度指数为0.88~1.85。

关 键 词:碎屑矿物  空间分布  空间自相关  景观生态学方法

Abstract:Based on the survey data, the spatial distribution characteristics of surface sediment debris minerals in Shenzhen Dapeng Bay, Guangdong, are analyzed using the method of spatial analysis, geological statistics, interpolation and landscape ecology. Also a spherical modeling of the semi-variogram of the mineral content distribution is established. The results show that the Hurst dimension of debris mineral ranges from 0.28-0.97, the geometric dimension ranges from 1.03-1.72. The index for Morans, I autocorrelation is -0. 15-0.53. At some spatial scale, the spatial information shown from the distribution of debris minerals by the Shannon-Wiener Index is 0.88-1.85.
Keywords:Distribution of debris mineral  spatial statistics and analysis  spatial autocorelation  landscaple ecology
