In the Mu Us desert, either vertical distributions of soil moisture isogram before irrigation or vertical distributions of soil moisture isogram after irrigation shows obviously vertical-layered character. When the irrigation is finished 24 hours later, there is little correlation between vertical distributions of soil moisture isogram before irrigation and vertical distributions of soil moisture isogram after irrigation. All of probability distribution of soil water content before irrigation are left-skewed distribution, but some of probability distribution of soil water content after irrigation is left-skewed distribution, some is right-skewed distribution or normal distribution. The distributed pattern shows different between the probability distribution of water depth of rain gauge and that of soil moisture in horizontal section of different depth. There is close correlation between the distribution of water depth of rain gauge and that of soil moisture in horizontal section, but the correlation debases as the horizontal section turns deeper. Also after irrigation close correlation occurs between the distribution of soil moisture of layers bordering upon each other, but which reduces with space of different layers being larger.

The results above showed:(1) The cultivars of large-flowered chrysanthemum are widely distributed in Beijing area with plentiful floral types and floral colors;(2) The cultivars with the rare types and colors are urgent for protection;(3) Most of the quantitative characters obeys to the normal distribution,some important traits agreed with skewed distribution.The probability grading can assist quantitative character in establishing new grading standards;(4) Most of qualitative characters is asymmetrical in cultivars,which might be caused by unbalanced differentiation of characters or linkages coming from emphasis characters selection;(5) The floral characters are relatively stable and have comparably large influence on classification,the characters of stipule also have a certain degree of stability and can act as an reasonable supplement for cultivars classification,but the foliar characters have worse stability and can only be recognized as lower level criterion.(6) The genetic relationship among the Flat-petaled group,the Quilled-petal group and the Spoon-petaled group are closest,which followed by the Filiform-petal group because of long-term selection pressure for the specialization of the petal tip loved by most people.The Anemone-petal group has further genetic relationship with these four groups.(7) ISSR molecular marker detection indicates that the proportion of polymorphic loci of lardge-flowered chrysanthemum is higher,in which the Flat-petaled group has the highest genetic diversity level.

cumulative frequency:累计频数

用频数表计算中位数时先据频数表计算累计频数(cumulative frequency)和累计频率,百分之五十分位数即为中位数. 中位数用于描述偏态分布资料的集中位置,它不受两端特大、特小值的影响,当分布末端无确切数据时也可计算.

Lognormal distribution:对数正态分布

Oakes(1998)指出,如果我们使用对数正态分布(lognormal distribution)的办法来描述语料分布,偏态就不会出现. 值得注意的是Alien & Seidenberg(1999)的研究,他们认为,在整个生成语法历史中一直没有弄清楚语言能力和语言运用的关系,其实两者不能截然分开,
