- 摘要:
- 选取了文山县新开田村的典型切沟作为对象，通过测定土壤性质、侵蚀钉及全站仪测量的方法进行研究。结果表明，该地区土壤水保功能较差；在雨季期间，切沟侵蚀程度较大，特别是沟头的溯源侵蚀，在一个雨季内估计能推进1 m左右；全站仪测量生成的三维图能有效地表征侵蚀沟的变化。
- Abstract:
- Typical gullies in Xinkaitian village of Wenshan county were chosen as objects to study their erosion variations through determinations of soil characteristics and erosion nail,and three dimension graph generated by total station.Following results were found out.Firstly,the local soil was in a state with weaken erosion-proof function;secondly,there was a more severe soil erosion in monsoon,especially for the headcut erosion at the inlet of the gullies with a capacity to expend by approximate one meter in a monsoon;furthermore,the three dimension graphs generated by Total station can effectively indicate the erosion variation of these gullies.
