摘要:
以川中丘陵区坡耕地生物埂为研究对象，采用野外调查与室内分析相结合的方法对坡耕地生物埂SS（桑树埂）、HJ（花椒埂）、ZH（紫花苜蓿埂）和CK（杂草埂）模式下的土壤抗蚀特征及其影响因素进行了分析。结果表明：（1）生物埂措施能有效增加土壤含水率和土壤有机质含量，提高土壤孔隙度，改良土壤结构；（2）通过主成分分析得到不同生物埂模式下土壤抗蚀性综合指数大小依次为HJ > SS > ZH > CK，因此抗蚀性大小依次为HJ > SS > ZH > CK；（3）利用相关性分析，得到影响土壤抗蚀性与土壤含水率、有机质、容重、孔隙度及机械组成呈显著或极显著关系。研究结果可为紫色土坡耕地生物埂防控水土流失提供依据。
Abstract:
In order to probe into the soil anti-erodibility characteristics and influences of 4 bio-banks on sloping farmland in purple soil area, this paper presents a comprehensive analysis of soil anti-erodibility in the models of soil bunds with mulberry, Chinese prickly ash, alfalfa and natural grass on sloping farmland in purple soil area through both field survey and indoor analysis. The result shows that:(1) the bio-bank approach increases the moisture of soil and content of soil organic matter effectively, improves the soil structure; (2) through principal component analysis, the comprehensive index of soil anti-erodibility in 4 sloping farmland bio-bank models decreases in the order:HJ > SS > ZH > CK. And their anti-erodibility decreases in the order:HJ > SS > ZH > CK; (3) correlation analysis indicates that soil anti-erodibility has obvious correlations with soil moisture, organic matter, bulk density, porosity and mechanic composition. The results may provide basis for controlling soil and water loss in purple soil area.
