    年輪元素分析系統(tǒng)在中科院寒旱所安裝運(yùn)行

    發(fā)布時(shí)間: 2015-09-09  點(diǎn)擊次數(shù): 2435次

    日前,由北京易科泰生態(tài)技術(shù)有限公司*代理的Multiscanner年輪元素分析系統(tǒng)在寒旱所公共實(shí)驗(yàn)室平臺(tái)完成安裝調(diào)試和使用培訓(xùn),這是目前上功能zui為強(qiáng)大的集X-光密度成像(CT)和XRF元素分析的年輪分析平臺(tái)。  


    MultiScanner年輪元素分析系統(tǒng)同時(shí)采用了XRF元素分析技術(shù)和X-射線數(shù)碼成像技術(shù)(CT),用于樹(shù)木年輪密度和元素分析。可測(cè)量的元素有Al、Si、P、S、Cl、K、Ca、Ti、Cr、Mn、Fe、Ni、Cu、Zn、As、Rb、Sr、Hg、Pb等。其的同類(lèi)產(chǎn)品為用于巖石樣芯、沉積樣芯密度與元素分析的CoreScanner。
    下圖是對(duì)某一年輪樣品CT/XRF分析結(jié)果,包括光學(xué)成像、X-光密度成像(CT,中間的高分辨率黑白圖像)及Ca在不同年輪中的濃度分布(藍(lán)色曲線)。


    MultiScanner不僅用于一般的年輪分析和古氣候、環(huán)境變遷等研究分析,Yvonne Fors等在2014年的《Nature》上還發(fā)表了應(yīng)用于海洋考古學(xué)研究的論文“Sulfur and iron accumulation in three marine-archaeological shipwrecks in the Baltic Sea: The Ghost, the Crown and the Sword "
    Colette等(2013)利用MultiScanner對(duì)加拿大不列顛哥倫比亞中西部河流不同樹(shù)木年輪寬度和密度進(jìn)行了分析,并據(jù)此重建了到AD1660年的年輪水文氣候,研究成果發(fā)表在《Hydrological Processes》(Dendrohydroclimate reconstructions of July–August runoff for two nival-regime rivers in west central British Columbia)。
    Charlotte等(2006)利用MultiScanner對(duì)森林樹(shù)木樣品年輪密度及Mn元素和Bi元素進(jìn)行了分析,以揭示氣候變化對(duì)樹(shù)木生長(zhǎng)的影響。研究成果發(fā)表在《Applied Geochemistry》(A dendrochemical study of Pinus sylvestris from Siljansfors Experimental Forest, central Sweden)。 


    下面這則案例則利用Multiscanner研究分析重金屬污染對(duì)樹(shù)木生長(zhǎng)的影響。
