And we have got the following result : 1. the technique of storing water in soil in gneiss area of tai - hang mountain : the more water in soil before rain is, the less water capability of soil is, the time shorter of water flowing from soil is, the easier the water flows on the ground ; the soil capability of reserving water of different soil thickness is terrace > acacia land > pine land > grass land, so the soil is more thick, the soil capacity which contains water is more large ; the accumulated water that flows on the ground is remarkable related with the logarithms of rain time
太行山片麻巖區土壤蓄水規律：雨前土壤含水量越高，土壤可蓄水量越小，出流所需時間越短，容易形成地表徑流；不同土層厚度的土壤蓄水量為：梯田刺槐林地油松林地草地；累積地表徑流量與降雨時間的對數呈顯著正相關，擬合方程為w = a + blnt ，相關系數均大於0 . 92 ，即在降雨強度一定的前提下，降雨時間越長，累計地表徑流量越多。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。
