坡沟系统是黄土高原重要的流域组成单元,是小流域侵蚀产沙的主要源地,又是控制水土流失、恢复与重建生态环境的基本治理单元,对其侵蚀现象与规律的探究,可为黄土高原地区土壤侵蚀治理措施的优化配置提供重要科学依据。对黄土高原坡沟系统的侵蚀方式、侵蚀形态的垂直分带性、坡沟系统侵蚀泥沙的来源、上方来水来沙对坡沟系统土壤侵蚀的影响、草被覆盖及其空间分布对坡沟系统侵蚀影响、淤地坝在坡沟系统土壤侵蚀研究中的应用等进行综述,指出在今后的研究中需要进一步开展侵蚀垂直分带结果和上方来水来沙对坡沟系统土壤侵蚀影响的定量分析,加强坡沟系统侵蚀泥沙来源、淤地坝对坡沟系统土壤侵蚀影响以及野外原状坡沟系统草被覆盖和空间分布对坡沟系统侵蚀影响的研究。
The slope ditch system is an important drainage basin unit in the Loess Plateau, which is the main source of soil erosion and sediment yield in small watershed. It is also the basic governing unit for controlling soil and water loss, restoring and rebuilding the ecological environment. The erosional phenomenon and law can be studied The Loess Plateau area soil erosion control measures to optimize the allocation of important scientific basis. Erosion patterns, vertical zonation of erosion patterns, source of erosion sediment in slope gully system, influence of incoming water and sediment on soil erosion in slope gully system, coverage of grass cover and its spatial distribution on slope The impact of ditch system erosion and the application of silt dam in the study of soil erosion in slope gully system are summarized. It is pointed out that in the future study, the vertical zonation of erosion and the effect of incoming water and sediment on soil erosion in slope gully should be further developed Quantitative analysis, to strengthen the erosion and sediment source of slope and gully system, silt dam on the impact of soil erosion on the slope gully system and the wild grassland slope gully system coverage and spatial distribution of slope gully system erosion.
