摘　　要：通过实地调查与试验分析,研究了汤旺河流域4种经营类型红松林对土壤性质的影响情况。结果表明:在研究地区无论土壤pH、土壤有机质,还是土壤养分和土壤物理性质,白桦与红松天然更新形成的混交林和白桦与红松人工造林形成的混交林都较红松人工纯林优越,维护林分土壤地力及涵养水分的功能强。而红松人工纯林较原始红松林和两种白桦红松混交林维护地力及涵养水分功能弱。研究结果为汤旺河流域森林恢复与重建提供了科学合理的途径。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.
