摘要:
流域地貌的水道结构是地表侵蚀地形的主要表现形式，是区域土壤侵蚀研究中的重要因子之一。利用野外实测与地形图量测相结合的方法，通过对贵州省不同空间尺度下的水道发育参数统计分析，研究表明贵州省地面组成物质对地表侵蚀形态的影响极为显著，不同类型地面组成物质发育的水道在水道频度与水道密度方面均表现出差异。同时，碳酸盐岩组所占的面积比例对地表水道发育有明显的影响并存在一定相关性。结论对该类地区区域土壤侵蚀的研究具有重要意义。
Abstract:
The water-way’s structure of watershed landform is a kind of expression for eroded landform,which is an important factor for regional soil erosion study.By using the method of combining fields investigation and map measurement,the paper has analyzed the water-way’s parameters under different spatial dimensions.The results show that the ground substances have significant impact on eroded landform and water-way’s frequency and density are different under different ground substances.Meanwhile,the area ratio of carbonatite group has obviously impact on water-way’s development and has a certain relationship.The results have important significance for regional soil erosion study under the same kind of area.
