| 摘 要： | 沼泽湿地属于一种特殊的生态景观条件。为了选择适合沼泽湿地区的多目标地球化学调查采样介质,在松嫩平原西部扎龙保护区开展了方法试验,采样介质主要采取沼泽湿地区的表层腐殖泥和基底冲积土2种介质。通过对比试验,反映出沼泽湿地区表层的腐殖泥是代表该景观区多目标地球化学调查的最佳采样介质。腐殖泥样品中的OrgC、N、S、Se、Hg、TC、U、Br、Au、TFe2O3、Bi、Cr、Ag、Li、Y、Mo、Cu、Sb等元素含量均高于其基底沉积物样品。这与沼泽湿地区的生态环境特征相吻合,而腐殖泥下部的冲积成因的基底物质属于外来物质,不能反映目前沼泽湿地区的生态环境特征,由此确定沼泽湿地区多目标地球化学调查最佳采样介质为表层的腐殖泥。 |

| Abstract: | The marsh wetland belongs to a special kind of condition.To choose right media proper to the multiobjective geochemical exploration in the Zhalong marsh wetland,the group of the program made method trials,and the media collected for the trials are mainly from humic soils on the marsh wetland surface or from the fluvial soils on the base.The results show that the humic soil is the best media for the multiobjective geochemical exploration in the landscape.The contents of elements contained in the samples from humic soils,such as OrgC,N,S,Se,Hg,TC,U,Br,Au,TFe2O3,Bi,Cr,Ag,Li,Y,Mo,Cu,Sb,etc,are more than those obtained in the samples from fluvial soils.The conclusion accords with the ecological environment characteristics;however,the fluvial substances under the humic soil are most from outside area,and couldn't reflect the ecological environment characteristics.Finally,the humic soil on the surface is the optimal media for the multiobjective geochemical survey in the swamp area. |
