李子口径流小区不同植被条件下降雨对土壤侵蚀的影响研究

A Study of Rainfall Influence on Soil Erosion under Different Vegetations in Lizikou Runoff Plots

  • 摘要: 采用径流小区实验的方法,在李子口小流域设立了6个不同植被类型的径流小区,研究径流小区不同植被条件下降雨对土壤侵蚀的影响,结果如下:(1)不同植被条件下,降雨对土壤侵蚀的影响可表现为撂荒地小区 > 农耕地小区 > 林地小区,降雨对林地的土壤侵蚀弱,林地对当地水土的保持能力强,最适合作为当地水土保持的植物措施。(2)总体上,6个径流小区的降雨量、降雨侵蚀力与地表径流量、径流深、土壤流失量之间的相关性均表现为显著正相关的关系,表明降雨对当地土壤侵蚀作用强,需重点防护。研究揭示了研究区降雨与土壤侵蚀的相关性,比较了不同植被条件下降雨对土壤侵蚀的影响,为水土保持的相关研究提供参考与借鉴。

     

    Abstract: Six runoff plots with different vegetation types were established to study the effects of rainfall on soil invasion under different vegetation conditions in the Lizikou small watershed. The results were as follows:(1) Under different vegetation conditions, rainfall impacts on soil erosion could be listed as the wasteland plots, the farming land, the forest land, in descending order. The soil erosion of forest land was weak, and the forest land strongly maintained local soil and water, which was most suitable as a plant measure for local soil and water conservation. (2) In general, it showed a significant positive correlation among rainfall, rainfall erosion and surface runoff, runoff depth and soil loss in the six runoff plots, indicating that rainfall had a strong local erosion effect, and needing people to focus on protection. The correlation was revealed between rainfall and soil erosion in the study area, the effects of rainfall were compared on soil erosion under different vegetation conditions, providing reference for related research on soil and water conservation.
