| Abstract: | [中文摘要]：提高土壤抗蚀性是防治土壤侵蚀、促进生态恢复的有效途径之一。以退耕1 a撂荒地作为对照,该研究通过对恢复30 a的刺槐、柠条、油松与刺槐-紫穗槐、油松-紫穗槐5种不同植被恢复模式进行土壤抗蚀性的探索研究，结果表明，与对照相比，不同植被恢复模式的土壤抗蚀性均明显增强，土壤有机质含量、土壤黏粒含量以及土壤颗粒间团聚程度显著提高。采用土壤有机质含量、水稳性团聚体含量、水稳性团粒平均质量直径、团聚度和分散系数等指标计算该区土壤抗蚀性，进行抗蚀性等量评价。不同植被恢复模式土壤抗蚀性大小顺序为：油松（PC16）、刺槐（RP）、柠条（AK18）、油松-紫穗槐（PA17）和刺槐-紫穗槐（RA20），纯林土壤抗蚀性强于混交林。该区采用油松、刺槐和柠条纯林恢复模式效果要优于油松-紫穗槐和刺槐-紫穗槐混交模式。
[英文摘要]：Improving soil anti-erodibility is the effective approach to prevent soil erosion and restore vegetation. One year abandoned land was taken as control, the soil-erodibility of five vegetation restoration models such as Robinia pseudoacacia L. (RP21), Caragana korshinkii Kom. (AK18), Pinus tabulaeformis Carr. (PC16), R.pseudoacacia-A.fruticosa (RA20), P. tabulaeformis-Amorpha fruticosa L. (PA17) were studied. The results showed that the soil anti-erodibility was improved obviously compared to fallow land. The contents of soil organic matter, clay particles and aggregate degrees between soil particles were increased obviously. Soil organic matter content, water-stable aggregates content, mean weight diameter of water stable aggregate, aggregate degree and dispersion coefficient were used to evaluate the anti-erodibility quantitatively. The order of anti-erodibility with different vegetation restoration models was: Pinus tabulaeformis Carr., Robinia pseudoacacia L., Caragana korshinkii Kom., P.tabulaeformis-A.furticosa and R.pseudoacacia-A.furticosa. In a word, the soil anti-erodibility of pure forest is higher than that of mix-forest in loess hilly area. |
