植被恢复的主要目的是控制和恢复崩塌沟壑，这是一种普遍而严重的灾害。华南的侵蚀区然而，其有效性很少被评估，特别是在陡峭的。崩落沉积和盛行的高强度降水事件期间。小茴香的作用。研究了林冠、生物结皮和根系对坡面侵蚀的影响。本研究通过降雨模拟实验。有效地减少了小孢子虫和紫芽孢杆菌。陡崩积层土壤产沙率（SR）分别提高了98.1%和86.6%。总体而言，冠层较低、密度较大、细根体积较大，表明马齿苋的生长性能较好。两种植物的冠层对降低SR和SR的作用和贡献率最大。而生物结壳的作用和贡献率略高于生物结壳。根的平均值。这些结果强调了低冠层、细根和保护的重要性。减少降雨侵蚀的生物结壳。研究结果为土壤保持和土壤质量的优化提供了理论依据。陡塌积矿床的管理方法。
Vegetation restoration typically aims to control and restore collapsing gullies, which are prevalently and seriously.eroded areas in South China. However, its effectiveness has rarely been evaluated, especially on steep.colluvial deposits and during the prevalent high-intensity precipitation events. The effects of Melinis minutifora.and Chrysopogon zizanioides on slope erosion, and the contributions of canopy, biocrusts, and roots were investigated.in this study via rainfall simulation experiments. M. minutifora and C. zizanioides effectively reduced.soil sediment yield rate (SR) on steep colluvial deposits by 98.1% and 86.6%, respectively. Overall, lower and.denser canopies and greater fine root volumes indicated better performance of M. minutifora compared to C..zizanioides. Canopies of both plants exerted the strongest effects and contribution rates for reducing the SR and.apparent interrill erodibility, while the effects and contribution rates of biocrusts were slightly higher than those.of roots on average. These results highlight the importance of low plant canopies, fine roots, and the protection.of biocrusts toward the reduction of rainfall erosion. The results add to the optimization of soil conservation and.management practices for steep colluvial deposits.
