Abstract An experiment was established on two economic forests of dry fruits sites in Matiyu small watershed.It aimed to find out the soil hydrology characteristics of economic forest of dry fruits in hilly area of central south of Shandong Province,and to provide scientific basis for economic forest benefits evaluation and itfs construction in earthy-rocky mountain area of north China.Results showed that the soil physical characteristics of economic dry fruits forest are obviously better than that of wasteland.The soil particle of economic dry fruits forest is much more than that of wasteland in 1～0.05 mm.Soil density of economic dry fruits forest is lower by 10.40% than that of wasteland,soil porosity and non-capillary porosity increases by 15.04% and 17.46%.The available water storage and maximal water storage of soil is higher by 4.07 mm and 18.36 mm in forest land than that in wasteland.The initial infiltration rate and final infiltration rate of forest land are 1.56 times and 1.52 times more than that of wasteland.Water absorption rate of litter is 168.52% in Castanea mollissima forest and 200.47% in Juglans regia forest.The litter layer of economic forest has high water-holding capacity,so the surface runoff can be decreased.Economic dry fruits forests can improve soil structure and form good soil hydrology characteristics in hilly area of central south of Shandong Province.
