| 摘 要： | 本文采用标准方法，测定了白洋淀北岸部分农田土壤的粒度组成、ｐＨ和有机碳含量等指标，对该地区土壤的特性进行了表征分析。结果表明，土壤的平均粒度分布大于２０μｍ的占５２．７３％，主要属于砂壤土。与１０年前相比，ｐＨ值变化不大；而有机碳含量是１０年前的１．２６倍。ｐＨ随土壤的垂直深度而略有增加，而有机碳含量则随土壤的垂直深度而减少。

| Abstract: | The particle composition, pH and organic carbon content of agricultural soil of north basin of Baiyangdian Lake were determined with standard methods in the paper, and the character of soil was studied using comparison method. The results show that the pH of surface soil is 8.318.77 and has mean value of 8.49 which does not have distinct variation to compare with 10 years ago; the organic carbon content is 0.77%1.21% and has a mean value of 0.96% which is 1.26 time of 10 years ago; sandy soil is main composition of studied soils. The results of vertical sample determination show that pH increases with soil column vertical depth and the organic carbon content is decreases with vertical depth. |
