| 摘 要： | 采用外加热法将土壤腐殖质(HM)及其组分富里酸(FA)和胡敏酸(HA)分别氧化后，采用光度法分析固沙工程的植被恢复(51, 43, 32, 20和0年)对腾格里沙地腐殖质及组分含量的影响;同时，采用红外光谱探讨其结构变化。结果表明，采用可见光谱学方法测定腐殖质及组分含量是可行的，结果重现性较好(变异系数最大为7.26%)，比传统容量法准确、快速、简便，具有能批量测定的优点。随恢复年限增加，腐殖质及其组分含量呈现增加趋势，胡富比也呈现增加趋势，说明植被固定改善了土壤质量，土壤腐殖化程度增加。傅里叶变换光谱结果表明植被恢复不同年限的沙土同一组分的红外光谱形状基本相似，但特征峰强度有明显区别。恢复年限增加，小分子糖类物质减少，芳族类物质增加，土壤水溶性有机物芳构化程度增加。 |

| Abstract: | After the potassium bichromate-strong sulfuric acid hot process,the ultraviolet spectrophotometer was used on the contrast with the traditional titrimetric method to analyze soil(51 years,43 year,32 year,20 year vegetations restores in the Tenggeli sand) humus and the humus components content At the same time,the infrared spectrum was used to discuss their structure change during restoring process.The result indicated that using the visible spectroscopy method for the determination of the humus and the humu... |
