| 摘 要： | 用田间试验法和径流小区法研究通南高沙土区土壤侵蚀特征 ,研究表明该区农田田面土壤输出量远小于田间沟道淤积量 ,淤积量为输出量的 4 7.3～ 5 6 .6倍 ,用径流小区测得的土壤侵蚀量不能完全反映高沙土区土壤侵蚀的特点。降水量、径流量、覆盖率和含沙量之间存在着密切的相关关系。 |

| Abstract: | The erosion characteristics of soil with high content sands were studied by means of the measures of farmland test and runoff plot respectively. The results were as follows: The quantity of soil erosion from the surface of farmland was much less silting quantity in the ditches, the later was 47.3~56.6 times larger than the former. The quantity of soil erosion from runoff plot can not reflect the erosion characteristics of high content sand areas. There were close relationship of precipitation, runoff, plant coverage and soil silting quantity. |
| Keywords: | soil with high content sands soil erosion runoff test |
