Caco3 not only affects soil physical and chemical characteristics but also causes co2 change in the air , because caco3 is main components among the total pool of inorganic carbon of soil . this paper systematically summarized and analyzed general development characteristics of soil profile caco3 in loess hill gully area including source , content , forming - condition , distribution and illuviation - depth of caco3 , which will have the most important significance for the further studies on global soil and climate change 碳酸鈣在土壤剖面中淀積的深度和類型是黃土高原土壤發育的重要標志,鈣積層是黃土高原土壤發育環境的歷史信息庫,同時土壤碳酸鈣作為土壤無機碳庫重要組成,它通過溶蝕后再結晶與大氣co _ 2之間進行物質交流來影響全球氣候變化。

The distribution and change pattern of soil co2 concentration in soil profile data are analyzed as well as its effect factors . a model for soil caco3 eluviation - illuviation is developed based on mechanism of soil chemical thermodynamic principle and applying other modeling experience for reference 本文以磚窯溝流域為例研究和分析了土壤剖面co _ 2濃度的分布變化規律及其影響因子;對土壤碳酸鈣淋溶錠積進行了定性、定量研究。

Soil caco3 eluviation - illuviation is a relatively complicate process , soil co2 is one of the important effect factors , which influences soil caco3 through controlling soil ph value and caco3 solution capability 土壤碳酸鈣淋溶淀積是一個復雜的過程,土壤中的co _ 2通過控制土壤ph值和碳酸鈣的溶解性來影響土壤碳酸鈣的淀積,是重要的影響因子之一。
