关于坡耕地土壤“翻滚侵蚀”的研究
- Title:
- Research of “Rolling Erosion” on Sloping Farmland
- Keywords:
- sloping farmland; soil; rolling erosion
- 分类号:
- S157
- 摘要:
- 所谓“翻滚侵蚀”，就是指坡耕地土壤在受到人为外力的作用下，而产生向下翻动、滚动和下切的侵蚀现象，其主要发生在坡耕地的耕作上，当在坡耕地上耕作时，每趟一遍地，其土壤就向下翻滚一点和下切一点，当坡度越大其翻滚的程度就越大，也就是说产生的翻滚侵蚀就越大。这种“翻滚侵蚀”现象在山区、丘陵区、漫川漫岗区的坡耕地耕作中是十分突出和十分严重的，不能不引起我们对它的高度重视。
- Abstract:
- The so-called rolling erosion,be pointed to the soil subjected to the outside,to produce rolling and down-cutting erosion phenomenon,its main occurrence is on sloping farmland,when farming,its soil get down a little bit and roll a little,the big the sloping is the big rolling degree is.This kind of "rolling erosion" phenomenon is outstanding and very serious on the sloping fields in mountain and hilly area,worthing our’s attention.
