片流坡面徑流 的英文怎麼說
中文拼音 [piānliúpōmiànjìngliú]
片流坡面徑流
英文
sheet flow-
The gullies are formed by the processes of infiltration - interflow - collapses. ( 2 ) in the slope with sand - loess, the major factors of water erosion are the rainfall intensity and rainfall amount of annual first rainfall. ( 3 ) in the region, the evolution processes of slope gully system results from alternative actions of sand deposition and water erosion
（ 1 ）有片沙覆蓋的斜坡小區，徑流量少，但徑流含沙率大，坡溝的形成過程是：垂直滲流坡地潛流崩塌； （ 2 ）在沙黃土斜坡小區，每年春末夏初降雨的強度及降雨量是決定坡面產沙量的關鍵因素； （ 3 ）該區坡溝系統的形成發育是風沙沉積、風蝕與水蝕交替作用的結果。When the rainfall intensity is steady, the time longer of rainfall is, the thinner of slope soil is, the more water in slope soil before rain is, the easier the water flows on the ground. 2
因此，在太行山片麻巖區，在一定的降雨強度下，降雨時間越長，坡面土壤層越薄，坡面土壤雨前的含水量越高，越容易形成地表徑流。The equation is y = a ebx, the interrelated coefficients are all larger than 0. 95 ; when the rainfalls are close, the volume of the surface runoff increases with the intensity of rainfall and the volume of the surface runoff is remarkable related with the maximum rain intensities of 30 minutes ; with the effect on rain harvesting acreage, the cover rate of the plants, the gradient, and the average soil thickness, the cover rate of the plants and the average soil thickness are the important factors which can affect the volume of rain harvesting. and the average soil thickness is the dominant factor. in order to get good result, we must choice the slope which the cover rate of the plants is low and the average soil thickness is thin, meanwhile increase the rain - harvesting acreage
太行山片麻巖區坡面集雨規律及集雨技術：集雨量與降雨量呈顯著正相關，並且在降雨量大於17 . 6mm時，集雨量隨降雨量的增加呈指數形式增加，擬合方程為y = ae ~ （ bx ） ，相關系數均大於0 . 95 ；降雨量相近的條件下，徑流量隨降雨強度的增大而增大，且在片麻巖山地， 30min最大雨強是影響產流的關鍵因子；在集雨面積、植被覆蓋度、坡度以及平均土層厚度等因素的共同影響下，植被覆蓋度和平均土層厚度是影響集雨量多少的主要因素，其中平均土層厚度是主導因素；而要想取得良好的集雨效果，必須在選擇植被覆蓋度低、坡面土層厚度薄的坡面的同時，加大集雨面積。
