The study was undertaken to determine the tendency and variation of the soil-water holding capacity during the restored vegetation community succession in a plot of former cropland bordering a typical steppe zone on the Loess Plateau. The curves of soil water characteristics measured by centrifugation showed: there was a high power function correlation between the soil moisture and the potential of soil water, which could be represented by θ=aS~b. Following the succession of the vegetations, the value...

The study was undertaken to determine the tendency and variation of the soil-water holding capacity during the restored vegetation community succession in a plot of former cropland bordering a typical steppe zone on the Loess Plateau. The curves of soil water characteristics measured by centrifugation showed: there was a high power function correlation between the soil moisture and the potential of soil water, which could be represented by θ=aS~b. Following the succession of the vegetations, the value a increased gradually. Soil water contents of various vegetations are different at the same range of soil water potential. The data indicated that the water content of soil covered with Stipa bungeana was the highest, while the land was the lowest in the slope, though at the same range of soil water potential. The soil water contents of other plant community successions reached the same level with the increase of soil water potentials. The vegetation succession lessened the soil bulk density and enhanced the soil porosity by increasing the soil organic matter and improving the soil construction; thus, affecting the soil-water holding capacity.

应用离心机法测定土壤水分特征,研究黄土高原典型草原带退耕地植被恢复演替过程中土壤持水性能的变化特点及趋势。结果表明:土壤含水量与土壤水吸力之间符合幂函数θ=aSb,参数a的变化随着植被的演替呈增加趋势;由于植被的影响,在同一吸力范围内的土壤含水量不同,植被为顶级长芒草(Stipabungeana)群落时,土壤在各吸力段的含水量最高,坡耕地最低;其它群落土壤含水量随着水吸力的增加变化趋于一致;退耕地植被在演替过程中通过提高土壤有机质含量改善结构,降低容重并增加毛管孔隙度,对土壤的储水和持水性能产生作用。

Content characteristic of arsenic in iron ores imported was investigated by statistical techniques.Based on data distribution,a brand-new robust statistics, kernel density estimation,coupled with bootstrap resampling method was introduced to acquire the representative value of arsenic content in imported iron ores.It is clearly demonstrates that this method shows a prior advantage to give a robust descriptions in explanation for central tendency and variation of data profiles.A bootstrap mean and interval...

Content characteristic of arsenic in iron ores imported was investigated by statistical techniques.Based on data distribution,a brand-new robust statistics, kernel density estimation,coupled with bootstrap resampling method was introduced to acquire the representative value of arsenic content in imported iron ores.It is clearly demonstrates that this method shows a prior advantage to give a robust descriptions in explanation for central tendency and variation of data profiles.A bootstrap mean and interval were provided,and further discussion was hold in detail.

对进口铁矿中的砷量进行了总体统计分析,在数据统计分布特征研究基础上,使用内核密度估计对进口铁矿砷量进行数据多态性分析,使用boot-strap对原始数据样本值重复取样以获得稳健的砷量代表值估计及标准偏差,证明以bootstrap重新取样样本分布的均值与标准偏差作为有限单次样本代表值是合理、有效的。
