中文摘要	为了阐明干旱区土壤含水量和土壤碳酸钙含量之间的关系，选择腾格里沙漠油蒿群落为研究对象，对80m80m样地内400个4m4m样方的土壤水分和碳酸钙的分布状况及二者含量之间的关系、空间异质性进行了研究。结果表明：腾格里沙漠油蒿群落土壤含水量呈均匀分布，碳酸钙含量呈小斑块分布；土壤含水量与碳酸钙含量之间存在显著的线性正相关关系，表明碳酸钙含量随着土壤含水量的增加而增加；土壤碳酸钙含量和土壤含水量空间异质性之间呈显著单调递增的幂函数关系。可见，干旱区土壤含水量和碳酸钙含量之间具有密切的关系，土壤含水量越高，碳酸钙淋溶和淀积作用加强，土壤碳酸钙含量也就随之升高。因而，土壤含水量是影响土壤碳酸钙形成的一个重要因素。
英文摘要	To reveal the relationship between water contents and calcium carbonate contents in soil in arid area, this paper focused on their distribution pattern, relation of their contents, and the relationship between their spatial heterogeneity in the community of Artemisia ordosica that located on the Tengger Desert. Sampling plot area was 80m * 80m, which contained 400 quadrats of 4m * 4m. The results indicated that in this sampling plot, soil water contents took uniform distribution, and calcium carbonate contents in soil presented little patch distribution. There existed a significant positive linear correlation between the water contents and the calcium carbonate contents in soil, which showed the calcium carbonate contents increased as the water contents, and there existed a significant positive power correlation between spatial heterogeneity of the water contents and the calcium carbonate contents in soil. Therefore, there is close relationship between the water contents and the calcium carbonate contents in soil in the community of Artemisia ordosica. Here, the higher the water content in soil is, the stronger the eluviations and precipitation of calcium carbonate is, and so the greater the content of calcium carbonate is. So it is concluded that the water content in soil plays an important role in the formation of pedogenic calcium carbonate in arid area.
