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。 -
( 4 ) wavy distribution of soil water along hillslope resulted from the fluctuation of runoff, upslope runoff infiltration, lateral downslope flow, and the difference of infiltration rate and evapotranspiration
（ 4 ）土壤水分沿坡面呈「波浪形」分佈是坡面徑流的波動性、上方來水（徑流）的沿程入滲、側向沿坡向下流以及坡面各處入滲性能和蒸發蒸騰作用的差異等綜合作用的結果。 -
Analyzing the different vegetation cover rate of impact on runoff energy, we draw the cutting rate for runoff energy would increase with the vegetation cover rate increased
（ 5 ）對不同植被蓋度對徑流能量的影響分析得出，植被蓋度越大，對徑流能量的削減率越大。 -
