【摘要】 [目的]探究成都市温江区道路绿地和校园绿地土壤抗蚀、抗冲特征及其影响因素，为城市绿地水土保持和生态可持续发展提供理论支持。[方法]采用野外取样与室内试验相结合的方法，对道路和校园绿地中乔木+草地、乔木+灌木、灌木、灌木+草地、草地开展土壤抗蚀抗冲性特征研究。[结果]>5 mm土壤水稳性团聚体含量在道路(79.72%)和校园绿地(39.23%)均表现为最大。土壤总孔隙度、土壤含水量和土壤粉粒含量均表现为：校园绿地>道路绿地(p<0.05)。土壤平均重量直径(MWD),土壤几何平均直径(GMD)、土壤抗蚀性指数、水稳性指数和抗冲指数均表现为：道路绿地>校园绿地(p<0.05),其中乔木+灌木和灌木+草地结构土壤抗蚀抗冲性优于其他植被结构，土壤抗冲系数均随坡度增大而减小。土壤抗蚀、抗冲性指数与>5 mm土壤水稳性团聚体、有机质含量和土壤黏粒均呈极显著正相关；与土壤团聚体破坏率(PAD),不稳定团粒指数(ELT)、<0.25 mm, 0.25～2 mm水稳性团聚体呈极显著负相关(p<0.01)。[结论]道路绿地乔木+灌木和灌木+草地结构土壤抗蚀抗冲性最好，校园绿地可以通过调整植被结构增强抗逆性和观赏性，降低土壤侵蚀风险。更多还原

【Abstract】 [Objective] The anti-erosion and anti-scouring characteristics and factors influencing road and campus green spaces in Wenjiang District, Chengdu City were analysed in order o provide functional guidance for urban green space soil and water conservation and promote ecologically sustainable development. [Methods] The soil anti-erosion and anti-scouring properties of arbour + grass, arbour + bush, bush, bush + grass and grass in road and campus green spaces were characterised through field sampling and laboratory tests. [Results] The >5 mm soil water-stable aggregate content was highest in both roads(79.72%) and campus green spaces(39.23%). Total soil porosity, soil water content, and silt content were greater in campus green spaces than road green spaces(p<0.05). Mean weight diameter(MWD), geometric mean diameter(GMD), soil anti-erosion, water stability aggregate index, and anti-scouring were all higher in the road green space than in the campus green space(p<0.05). Specifically, the anti-erosion and anti-scouring of arbour + bush and bush + grass structures were better than that of the other vegetation structures, and the soil anti-scouring coefficient decreased with increasing landscape slope. Soil anti-erosion and-scouring were positively correlated with >5 mm soil water-stable aggregates, organic matter content, and soil clay particles, and negatively correlated with the percentage of aggregate destruction(PAD), unstable aggregate index(ELT) and <0.25 mm and 0.25～2 mm water-stable aggregates(p<0.01). [Conclusion] Arbour + bush and bush + grass had the best soil anti anti-erosion and-scouring effects on road green areas. Campus green space can reduce the risk of soil erosion by adjusting the vegetation structure, thereby enhancing the stress resistance and ornamental property.更多还原
