中文摘要：

以黑龙江多宝山和铜山矿区为例,通过采集矿区典型植物的光谱,以及岩石、土壤、植物中14种金属元素和植物叶片生化参数的测试分析,表明不同植物选择性吸收富集的金属元素不同,分别与岩石、土壤不同层中金属元素含量的相关性不同。由于植物叶片对金属元素富集,植物胁迫光谱的变异体现在光谱的‘红边’和吸收深度不同,而植物光谱的变异特征与其粗蛋白和叶绿素（a、b）含量相关,与叶绿素a的相关性更强。通过叶片内重金属元素含量和550～760nm之间波段吸收深度的多元回归分析,表明叶片中Co,Cu,Ni,Mo,Ag,Sb,W,Pb和As的含量与其光谱吸收深度的复相关系数都在0.75以上,相关性强。通过此研究,为植被覆盖区利用高光谱遥感调查评价金属元素的分布和富集奠定基础。

英文摘要：

In this paper,Duobao Mt.and Tong Mt.were taken as examples.The spectra of the crown or leaf of the vegetation were collected.Fourteen metal elements in the rock,soil（A,B,C） and vegetation（root,trunk,leaf）,and biological chemical parameters were measured.It was indicated that different metal elements were selected and enriched in different vegetation.The red edge position（REP） and the absorbing depth are related to biological chemical parameters.A multivariable regression equation was built between the absorption depths and the contents of metal elements.The relative coefficients between the absorbing depths and chemical elements,including Co,Cu,N,Mo,Ag,Sb,W,Pb and As,are greater than 0.75.Thus,it is important to analyze and measure the contents of metal elements by hyper-spectral remote sensing of vegetation stress spectrum.
