细沟

This patio is crossed by a small rill connecting a stone basin with a square reflecting pool adjacent to the living room.

In the paper, we mostly studied the change of soil erosion process by a new REE tracer method, based on the theories of hydraulic mechanical subject and radionuclear tracer method, and simulated rainfall was applied to study the sheet erosion changing to rill erosion and the rill erosion process on slope land. The new REE tracer method should be useful to future studying of erosion processes on slope lands.1. Offering and testifying a new REE displacing method to study on the soil erosion of the loess slope.

本文以黄土坡面土壤侵蚀形态演变规律为研究重点，以新的核素示踪技术为手段，采用水动力学与核素示踪技术相结合、室内人工模拟降雨与稳定性REE元素示踪相结合的方法，利用先进的INAA技术，定量研究了不同雨强次降雨条件下细沟间侵蚀向细沟侵蚀的转变过程、细沟发生发育过程，为深入了解坡面侵蚀过程，建立黄土高原土壤侵蚀预报模型提供了研究基础。

The results indicate that the main erosion type is sheet ero-sion at the beginning of the rainfalls, and serious erosion happens after rill erosion appears. Accumulated sheet and rill erosion amount increases with the rainfalls time. The percentage of sheet erosion amount decreases and rill erosion percent-age increases with time. At the end of the rainfalls, the total rill erosion amounts are 4.3 and 5 times more than sheet ero-sion.

研究结果表明，降雨初期坡面以面蚀为主，细沟出现后，坡面侵蚀将加快加剧；随着降雨时间的延续，累积面蚀量和细沟累积侵蚀量都将逐渐增加，后者的增加速率大于前者，面蚀所占总侵蚀量的百分比随降雨时间呈曲线形式逐渐递减，细沟侵蚀则逐渐增加；试验结束时细沟侵蚀量分别为面蚀量的4—5倍。

Quantitatively studying on the change of accumulated sheet and rill erosion amounts.Sheet erosion rate firstly gradually increased, then rapidly increased and finally remained stable with the rainfalls time, but the rill erosion rate increased more quickly than sheet erosion rate and the value of rill erosion rate was higher than of sheet erosionrate.

定量分析了次降雨条件下累积面蚀量、细沟累积侵蚀量及面蚀率、细沟侵蚀率随时间的变化在试验条件下，随着降雨的进行，坡面面蚀率先缓慢增加趋势后基本保持稳定，而细沟侵蚀率具有随降雨时间急剧增加现象。

The soil erosion process on the slope was clearly divided into sheet erosion stage, rill erosion developing stage and rill erosion stable stage. Before lOminutes of rainfalls, the percentage of sheet erosion amount to total erosion amount was more than 90%, and it indicated that sheet erosion happened on the slope. This percentage sharply decreased before SOminutes of rainfall time, on the other hand, the percentage of rill erosion amount to total erosion amount increased in curve form with rainfall time.

在降雨前10min左右，面蚀贡献率约占坡面侵蚀总量的90%以上，为面蚀阶段；随着降雨时间的延续，面蚀贡献率先急剧递减最后在第30min左右基本达到稳定，细沟侵蚀贡献率则出现相反趋势，此为细沟发育阶段；降雨后期，面蚀和细沟侵蚀贡献率的变化趋势逐渐变缓且基本达到稳定。

Besides, when the experimental soil was clay soil of Yangling, the appearance and developing process of rill erosion happened respectively 12-15min and 4-8min earlier than of silt soil of Shaanbei.Accumulated sheet and rill erosion amounts increased with the rainfalls time, and the latter increased quickly than the earlier. The total accumulated rill erosion amounts were 2.5 and 5.5 times more than accumulated sheet erosion amounts.

黄绵土坡面发生细沟侵蚀的时间早于粘黄土坡面12-15min；坡面细沟侵蚀达到稳定的时间粘黄土坡面也比黄绵土坡面滞后约4-8min；累积面蚀量和细沟累积侵蚀量均随降雨时间的延续而增加，且后者增加幅度明显大于前者；降雨结束时，坡面细沟累积侵蚀量约为累积面蚀量的2.5～5.5倍，约占坡面总侵蚀量的80％以上。

Based on the result of field artificial rainfall experiments on 60m length slopes,sedi-ment delivery is consisted of raindrop impact,slope runoff and rill flow delivery.Accord-ing to their functions,rill was ranked firstly then slope run off,and last raindrop impact.

通过野外60m坡面人工降雨实验及过程结果分析可知：输移由雨滴击溅、坡面径流和细沟输移三部分组成，按作用大小来排，细沟流占第一位，坡面径流占第二位，雨滴击溅最小。

From the viewpoint of self-organization, rainfall and micro-landform are corresponding to the disarranged input and the rills are corresponding to the regular output.

其中，降雨及微地貌对应于自组织系统中的无序输入，而纹沟、细沟和沟网等对应于自组织系统的有序输出。
