  1. 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濃度的分佈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。
  2. The study on soil co2 concentration redounds to understanding and illustrating the inner mechanism of caco3 deposition process and provides experiment data for caco3 deposition model development. based on the two years located research and out - door investigation in zhuanyaogou watershed, hequ county, the north west of shanxi province

    研究土壤co _ 2濃度在剖面上的分佈和變化規律，有助於認識和解釋黃土高原鈣積過程的內在機制，以土壤co _ 2濃度變化的實測數據，建立能更準確描述鈣積過程的模型。
  3. The results indicated that even if there was different at initial soil condition, such as initial moisture content and initial salt content, salt content in soil profile and sar at top soil increased greatly after the high salinity water infiltrated

    結果表明盡管土壤初始條件存在差異，但灌高礦化度水后，土壤含鹽量和溶液濃度總體增加，且土壤剖面特別是表層的sar明顯增大。
  4. 2. according to the weighted average, soil co2 concentration is 0. 58 - 13. 29 times of that in atmosphere and is relatively lower than similar research, meanwhile, soil co2 concentration in profile varied irregularly, which possibly is due to the chemical and physical characteristic of loess soils, season change and arid climate etc. the variation of soil co2 concentration in profile is mainly controlled by soil temperature and soil moisture, in contrast with soil temperature, the control role of soil moisture is minor. in conclusion, in order to have a good command of the distribution and change rule of soil profile co2 concentration as well as its effect factors, multi - point and successive location experiment should be made, meanwhile establish indoor soil - pillar monitoring experiment

    土壤co _ 2的濃度約為大氣co _ 2濃度的0 . 58 ? 13 . 29倍與同類研究相比要低，這是與黃土的土質特性，觀測期又逢特別乾旱年制約了土壤微生物的活動，再加上土壤中有機質虧損，養分不足造成的；土壤co _ 2含量的變化是隨溫度的升高而升高，在夏季達最高值，冬季最低；在土壤co _ 2濃度變化的影響因子溫度和水分中，溫度的影響作用高於水分；土壤剖面co _ 2濃度隨著深度增加，總的變化趨勢是遞增的，但也有反復，甚至有的順剖面而下幾乎保持一恆值，這與季節變化和黃土自身結構的通透性以及在觀測期內的乾旱氣候等條件有關。
