Abstract To find out the variant rule of soil water resources in different forests and then provide scientific basis for vegetation rehabilitation in rocky mountainous area of north China, soil physical structure and characteristics of soil water of five artificial forests are studied in Shengquan temple forestry center in the southern mountainous area of Jinan city. Results indicate that in these forest, some indexes expressing soil pedonydrological physical character, such as soil density, porosity and infiltration rate, are much better than those in bare land, and these characteristics show this order: mixed forest>pure forest, Kalopanax septemlobus >Koelreuteria paniculata and Pistacia chinensis. In dry and rainy season, with the increasing of soil depth, soil water content decreased in most of forests, and their variant range is less than that in bare land. With the increasing of soil depth, soil saturated water content decreased in all kinds of forests. Soil retention capacity of surface layer is the best in the mixed forest, while differences are little in other forests. Conclusions show that judging from water conservation and validity, mixed forest is better than pure forest, and in pure forest Kalopanax septemlobus is batter and Koelreuteria paniculata in worse. Therefore, it is proposed that in the future mixed forest should be afforested and managed firstly, the species being made up of Kalopanax septemlobus and Pistacia chinensis. In the pure forest, Kalopanax septemlobus should be selected.
