Through field investigation and experiment analysis, the effects of four management types of Pinus koraiensis forest on soil properties around Tangwang river were studied. It is show that the soil properties of Betula platyphylla - Pinus koraiensis mixed forest are better than that of artificial Pinus koraiensis pure forest. These properties include pH, soil organic matter,soil nutrient and soil physical charactors. Betula platyphylla-Pinus koraeinsis mixed forest can maintain higher soil fertility and water capacity than that of artificial Pinus koreaiensis pure forest. And ability of artificial Pinus koraiensis pure forest for maintaining fertility and holding water is weaker than that of virgin Pinus koraiensis forest and Betula platyphylla-pinus koraiensis mixed forest. Study results provide a scientific way for recovery and rebuilding forest ecosystem around Tangwang river.
