The content and distribution of organic and inorganic carbon in soils of Rostov agglomeration were studied. The results obtained by the direct method of combustion catalytic oxidation on a TOC-L CPN Shimadzu carbon analyzer and by the indirect method of wet combustion of organic compounds were compared. The difference in the carbon contents obtained by these methods was the greatest in the root-saturated sod horizons, where it varied from 0.02 to 0.67%; in the humus-accumulative horizons, it did not exceed 0.12%. Generally higher values were obtained by the method of catalytic combustion.

In the light-humus A b horizon of the soils buried under the urbic stratum, a statistically reliable decrease in the organic carbon content in comparison with that in the A horizon of the natural surface soils was observed. Middle-profile carbonate-accumulative horizons of the buried and surface soils (B b and B) were characterized by approximately similar contents of both organic and inorganic carbon attesting to the low anthropogenic influence on these horizons. The lower (C) horizons of the buried and surface soils reliably differed in the contents of inorganic carbon, which was higher in the natural surface soils.

Data on the diagnostic urbic horizons were conditionally divided into two clusters of sandy and clay horizons. However, this attempt to arrange the results of the organic carbon measurements did not show any definite regularity in the distribution of organic carbon in the urbic horizons because of the high variability of this indicator.

研究了罗斯托夫聚结土壤中有机碳和无机碳的含量和分布。比较了在TOC-L CPN Shimadzu碳分析仪上通过直接燃烧催化氧化的方法和通过有机化合物湿燃烧的间接方法获得的结果。通过这些方法获得的碳含量差异在根部饱和草皮层中最大，在0.02％至0.67％之间变化。在腐殖质积累的视野中，不超过0.12％。通常，通过催化燃烧的方法获得更高的值。

在浅层腐殖质埋没在地表下的土壤中，与天然表层土壤的A层相比，有机碳含量在统计上可靠地下降。埋藏土壤和表层土壤（B b和B）的中等剖面碳酸盐岩累积层的特征是有机碳和无机碳的含量大致相似，证明了对这些层系的低人为影响。掩埋土壤和表层土壤的较低（C）层可靠地不同了，无机碳的含量不同，而天然表层土壤中的较高。

有条件地将有关诊断性尿层地层的数据分为两类沙质和粘土地层。然而，由于该指标的高度可变性，这种试图安排有机碳测量结果的尝试并未显示出在城市范围内有机碳分布的任何明确规律性。
