0統計軟體進行數據處理，結果顯示： 1 ）皺邊石杉中石杉堿甲含量與年平均溫度呈負相關、與土壤中速效k的含量呈正相關。 -
The metals transported in the various forms by the above processes can be co - consolidated with carbonate precipitation in the top soil, can easily be extracted by ho ac. the structure, weight and mineral constituents of loess change with varies on concentration of ho ac : the boundary between the grain become unclear after different gradually, but when hoac > 3 %, the weight change become smaller. also with increasing of ho ac concentration, the carbonates in loess decreases gradually, while hoac > 3 %, the change become smaller
不同濃度醋酸提取，黃土的結構、重量和礦物組成發生不同變化：黃土團粒界限變得模糊並出現孔洞，可能說明次生碳酸鹽在黃土中主要成膠結物存在；隨醋酸濃度增高，黃土重量逐漸降低，但當醋酸濃度大於3后，重量變化明顯變小；黃土中碳酸鹽礦物含量逐漸降低，當醋酸濃度3后，變化范圍明顯變小。 -
The n ( subscript org ) contents of samples dried at 105 was highest among the samples of field - fresh, being fumigated with chcl3, drying at temperature of room, 40 and 105 which came from not only a part of the microbial biomass nitrogen, but also from the decays of large organic molecules of soil nitrogen constituents
