| 摘 要： | 运用地统计学对莲花湖库区红松水源涵养林表层土壤水分-物理性质进行了空间异质性分析。研究结果表明: 土壤含水量、土壤密度、毛管孔隙度、非毛管孔隙度等因子均服从对数正态分布;毛管孔隙度最优拟合模型是球状模型,其它因子均为指数模型。土壤含水量、土壤密度、毛管孔隙度和非毛管孔隙度块金值、变程、结构比、分数维和空间自相关系数最大值分别为0.311、0.297、0.192、0.293,6.87 m、10.29 m、8.31 m、8.88 m, 0.690、0.694、0.814、0.707,1.968、1.939、1.937、1.945,0.111、0.200、0.246、0.157。可见以上4个因子空间自相关性均较强,随着空间距离的增大,其相关性逐渐减弱。其中毛管孔隙度均一性程度较高;土壤含水量空间分布形态较复杂,破碎化程度高。

| Abstract: | Spatial distribution characteristics of soil moisture-physical properties in water conservation forest of Pinus koraiensis in Lianhua Lake reservoir area were analyzed by geostatistics.The results showed soil moisture content,soil bulk density,capillary porosity and non-capillary porosity all exhibited lognormal distribution.The optimum fitting model for capillary porosity was spherical model;that for the other factors was exponential model.For soil moisture content,soil bulk density,capillary porosity and ... |
