| 摘 要： | 按照背景值的采样要求,采集了第二松花江流域(除长白山外)72个土壤剖面的200多个样品。用原子吸收法、阳极溶出伏安法和荧光光度法等测定了镉、铬、铜、铁、汞、锰、镍、铅、硒、锶、锌等元素的含量,得出全流域及流域内不同地区暗棕色森林土、白浆土、黑土、暗色草甸土、水稻土的元素背景值。 本文探讨了土壤类型、成土母质和土壤利用状况对背景值的影响,指出土壤背景值的地域差异性。地理单元划分越细,其土壤背景值的实用性越强。

| Abstract: | In observance with requirements for specimens sampling, over 200 samples in 72 soils profiles of Second Songhua River Basin were collected. Certain elements of Cd, Cr, Cu, Fe, Hg, Mg, Mn, Ni, Pb, Se, Sr, and Zn were determined with atomic adsorption spectrophotometry, anodic stripping voltammetry and fluorescence spectrophotometry. Background values of these elements in dark brown forest soil, Baijiang soil, black soil, dark meadow soil and paddy soil in this basin were obtained.This paper tries to find out the influence of soil types, soil-forming rocks and utilizing condition of soils on background values, and point out the regional difference in background values of soils, and concludes that the smaller the geographic region is classified, the greater the pragmatic value of background values is. |
