【摘要】：在河南仰韶村文化遺址內(nèi),分別選取一個受到古人類活動干擾的土壤剖面(簡稱文化剖面)和沒有受到古人類活動干擾的土壤剖面(簡稱自然剖面),通過分析土壤的粒度、磁化率、色度、礦質(zhì)全量、全磷含量和容重特征,比較兩剖面差異,從而獲取古人類活動對土壤理化性質(zhì)的影響。研究結(jié)果顯示:文化剖面土壤各理化性質(zhì)變異系數(shù)均較自然剖面大。文化剖面通體粒度組成偏砂,在灰燼層砂粒含量達到最大,但在文化層黏粒含量達到峰值,平均粒徑和分選系數(shù)變化明顯,均在灰燼層和文化層出現(xiàn)峰值和極大值;低頻磁化率(χlf)高于自然剖面,在灰燼層和文化層出現(xiàn)峰值,頻率磁化率(χfd)略低于自然剖面;紅度(a*)、黃度(b*)、亮度(L*)低于自然剖面,在灰燼層均出現(xiàn)最小值;各礦質(zhì)元素變異系數(shù)大于自然剖面,但含量幾乎相近,脫硅富鋁化程度較弱于自然剖面,在灰燼層中CaO、MnO含量達到最大值,在文化層中除SiO_2幾乎無變化外,其余氧化物或出現(xiàn)最大值或波峰;容重平均值小于自然剖面,并且在文化層出現(xiàn)最小值;全磷含量高于自然剖面,在灰燼層和文化層出現(xiàn)峰值和最大值。
[Abstract]:In the Yangshao Village Cultural site in Henan Province, one soil profile (referred to as the cultural section) which was interfered with by paleo-human activities and a soil section (called "natural section") that were not interfered with by paleo-human activities were selected, respectively, and the particle size of the soil was analyzed. Magnetic susceptibility, chromaticity, total mineral content, total phosphorus content and bulk density were compared between the two profiles, and the effects of paleo-human activities on soil physical and chemical properties were obtained. The results showed that the coefficient of variation of soil physical and chemical properties in cultural profile was higher than that in natural section. In the cultural section, the content of sand grains in the ash layer reaches the maximum, but the clay content reaches the peak in the cultural layer, the average particle size and the separation coefficient change obviously, and the peak value and maximum value appear in both the ash layer and the cultural layer. The low frequency susceptibility (蠂 _ (lf) is higher than the natural section, the peak value appears in the ash layer and the culture layer, the frequency magnetic susceptibility (蠂 _ (fd) is slightly lower than the natural section, the red (a *), the yellow (b *), the brightness (L *) is lower than the natural section, and the minimum value appears in the ash layer. The coefficient of variation of each mineral element is larger than that of natural section, but its content is almost the same. The degree of desilication and aluminization is weaker than that of natural section. The content of CaOO _ (MnO) in ash layer reaches the maximum value, and in the cultural layer, except SiO2, there is almost no change. The average bulk density is smaller than the natural section and the minimum value appears in the cultural layer. The total phosphorus content is higher than that in the natural section, and the peak and maximum value appear in the ash layer and the cultural layer.
