(三)關(guān)于區(qū)域化變量的平穩(wěn)假設(shè)

從公式γ(x,h)= 中不難看出,估計(jì)[EZ(x)-Z(x+h)]2需要有若干對(duì)Z(x)和Z(x+h)的值,但在研究自然界的客觀事物中,不可能在空間的同一點(diǎn)上重復(fù)得到兩個(gè)樣品。因此,上述公式只是一個(gè)理想的理論公式,在實(shí)際應(yīng)用中無(wú)法實(shí)現(xiàn),因?yàn)樗环鲜挛锏目陀^實(shí)際。但是變差函數(shù)畢竟深刻地刻畫了區(qū)域化變量的(隨機(jī)性)和空間(結(jié)構(gòu)性)兩重性質(zhì)。為了正確運(yùn)用它就必須克服這個(gè)實(shí)際困難而賦予一定應(yīng)用條件的辦法是解決這個(gè)困難的選擇。給出在什么情況下,應(yīng)用是正確的,會(huì)取得好的效果,什么情況下應(yīng)用是不適宜的(不能取得正確結(jié)果)。于是提出了平穩(wěn)(stationary)假設(shè),是英文“stationary”一詞處于固定不變狀態(tài)的意思。這就是說(shuō)在某種平穩(wěn)狀態(tài)存在的條件下,[Z(x)-Z(x+h)]2是可求的,便能夠克服在空間同一點(diǎn)上不能重復(fù)取得兩個(gè)樣品帶來(lái)的困難和缺憾。從而使估計(jì)變差函數(shù)值得以實(shí)現(xiàn)。

在實(shí)際的地質(zhì)現(xiàn)象中,根據(jù)統(tǒng)計(jì)推斷的需要,在線性地質(zhì)統(tǒng)計(jì)學(xué)中,最普遍使用的假設(shè)有二階平穩(wěn)假設(shè)、本征假設(shè)和準(zhǔn)平穩(wěn)假設(shè)。在這兩種假設(shè)下,在確定的領(lǐng)域內(nèi),有效數(shù)據(jù)可以滿足統(tǒng)計(jì)推斷的需要。

1.二階平穩(wěn)假設(shè)(又稱弱平穩(wěn)假設(shè))

所謂二階是借用線性代數(shù)行列式概念,含有兩行兩列的行列式稱二階行列式(n=2),有兩個(gè)未知量。一般地說(shuō),當(dāng)區(qū)域化變量Z(x)滿足下列兩個(gè)條件時(shí),便稱其為二階平穩(wěn)假設(shè)。

1)在整個(gè)研究區(qū)(如礦化帶內(nèi)或礦體內(nèi))內(nèi),Z(x)的數(shù)字期望存在且等于常數(shù):E[Z(x)]=m(常數(shù))。

2)在整個(gè)研究區(qū)(如礦化帶內(nèi)或礦體內(nèi))內(nèi),Z(x)的空間協(xié)方差的函數(shù)存在且平穩(wěn)(即只依賴于基本步長(zhǎng)h,而與x無(wú)關(guān))。即

地質(zhì)統(tǒng)計(jì)學(xué)(空間信息統(tǒng)計(jì)學(xué))基本理論與方法應(yīng)用

當(dāng)h=0時(shí),就有Var[Z(x)]=C(0)(說(shuō)明方差存在且等于常數(shù))。

2.本征假設(shè)(intrinsic assumption)

當(dāng)區(qū)域化變量Z(x)的增量[Z(x-)Z(x+h)]滿足:

1)在整體研究區(qū)域內(nèi)有:

E[Z(x)-Z(x+h)]=0

2)其增量[Z(x)-Z(x+h)]的方差函數(shù)存在且平穩(wěn)(不依賴于x)。

2γ(x)=Var[Z(x-)Z(x+h)]=E[Z(x)-Z(x+h)]-2{E[Z(x)-Z(x+h)]}2=E[Z(x)-Z(x+h)]2,顯然γ(h)= 這時(shí),則稱Z(x)滿足本征假設(shè),或者說(shuō)Z(x)是本征的。

從上式可以看出,在以向量 相隔的兩點(diǎn)x和x+h處區(qū)域化變量的兩值Z(x),Z(x+h)的變異程度,是以它的增量平方的數(shù)學(xué)期望來(lái)表示的。這就告訴我們?cè)谘芯繀^(qū)內(nèi)的某一區(qū)域化變量時(shí),需要考慮區(qū)域化變量Z(x)是否滿足本征假設(shè)和弱平穩(wěn)假設(shè)條件,如果不考慮其平穩(wěn)條件,便不會(huì)得到最佳的結(jié)果。

一般說(shuō)來(lái),二階平穩(wěn)假設(shè)(弱平穩(wěn)假設(shè))是研究區(qū)域化變量Z(x)本身的特征,而本征假設(shè)是研究區(qū)域化變量增量[Z(x)-Z(x+h)]的特征。由此可知某個(gè)區(qū)域化變量Z(x)可滿足二階平穩(wěn),則一定可滿足本征假設(shè)平穩(wěn),反之則不一定(這里不證明,讀者可根據(jù)需要查閱相關(guān)專業(yè)書)。

自然界中的區(qū)域化變量Z(x)往往是復(fù)雜的。而又要考慮到某現(xiàn)象的相似尺度,和在相似尺度范圍內(nèi)得到的有效數(shù)據(jù)(信息)有多少。如果不能很好地滿足二階平穩(wěn)假設(shè),如本征平穩(wěn)假設(shè)條件。這時(shí)就要依據(jù)實(shí)際的需要和可能作個(gè)變通。于是又有了準(zhǔn)平穩(wěn)假設(shè)和準(zhǔn)內(nèi)蘊(yùn)平穩(wěn)假設(shè)的提出,準(zhǔn)平穩(wěn)假設(shè)和準(zhǔn)內(nèi)蘊(yùn)平穩(wěn)假設(shè)實(shí)際上是指在相對(duì)小的空間范圍內(nèi)存在的平穩(wěn)條件。

3.準(zhǔn)二階平穩(wěn)(quasi-stationary)假設(shè)及準(zhǔn)本征假設(shè)

如果隨機(jī)函數(shù)只在有限大小的鄰域(例如以a為半徑的范圍)內(nèi)是平穩(wěn)的(或內(nèi)蘊(yùn)的),則稱該隨機(jī)函數(shù)服從準(zhǔn)二階平穩(wěn)(或準(zhǔn)本征)假設(shè),它是通過(guò)縮小范圍而得到平穩(wěn)性,它既考慮到某現(xiàn)象相似性尺度(scale),也顧及有效數(shù)據(jù)的多少。我們知道,結(jié)構(gòu)函數(shù)(協(xié)方差或變差函數(shù))只能用于一個(gè)限定的距離|h|b時(shí),區(qū)域化變量Z(x)和Z(x+h)就不能認(rèn)為同屬一個(gè)均勻帶,這時(shí),結(jié)構(gòu)函數(shù)C(h)或γ(h)只是局部平穩(wěn)的,所以,我們把只限于|h|
