生物治理措施是土壤侵蚀防治三大措施之一，而土壤抗蚀性是评定土壤抵抗侵蚀能力的重要参数，该文以第四纪红壤为对象，对水保林、林草结合、果林清耕、撂荒裸地四种治理模式下土壤抗蚀性进行了研究，结果表明：（1）不同生物治理模式下土壤抗蚀性差异明显，土壤抗蚀指数表现为水保林>林草结合>果林清耕>撂荒裸地，且同一治理措施上层土壤抗蚀性优于下层土壤。（2）土壤抗蚀指数随浸水时间的增加而减小，两者呈三次函数关系。（3）运用主成分分析方法，从13个土壤抗蚀性影响因子中提取出3个主成分，建立土壤抗蚀性综合评价模型，在不同生物治理措施下适用良好。
Abstract
Abstract: Biological measure is one of the three major measures for soil and water conservation and soil anti-erodibility is one of the important parameters for evaluating the ability of soil resistance to soil erosion. This paper studied anti-erodibility of four different biological measures of red soil including soil and water conservation, combing forest with grass, pure fruit forest and bare abandoned land. The results showed that: (1) There is significant difference in anti-erodibility of different biological measures. The order of soil anti-erodibility index followed that soil and water conservation > combing forest with grass > pure fruit forest > bare abandoned land, and the anti-erodibility of upper layer was better than lower layer for the same measure. (2) The soil anti-erodibility index decreased with the increase of the immersion time going, it had cubic polynomial function relation with immersion time. (3) Three principal component of soil anti-erodibility could be determined from thirteen anti-erodibility indices by the method of principal component analysis. Then the comprehensive evaluation model of anti-erodibility was found, which was applied well under different biological measures.
