| 摘 要： | 以辽东山区天然次生林中3种(大、中、小)林窗为对象,通过对林窗内土壤养分质量分数的监测,探讨了林窗形成早期对土壤养分状况的影响.结果表明:与非林窗(对照林分)相比,3种林窗对土壤有机碳、全氮和全磷的质量分数无显著影响;而土壤铵态氮、硝态氮、速效磷和微生物生物量磷的质量分数则显著增加(P

| Abstract: | Effects of gap sizes on soil nutrients in the early stage of gap formation were studied by observing soil nutrients within the gaps with three different sizes(large,medium and small) in secondary forests in eastern Liaoning Mountainous Region,China.Results showed that,compared with the forest stands(the control),there were no significant differences in soil organic carbon,total nitrogen and total phosphorus among the three gaps of different sizes.Ammonium nitrogen,nitrate nitrogen,available P and microbial ... |
