摘要:
 计划烧除是预防森林火灾的重要措施，为了正确评价计划烧除后生态环境的响应，以滇中云南松天然次生林为研究对象，通过野外调查取样和室内测试分析相结合的方法，探讨了一年一度的周期性连续低强度计划烧除对云南松林土壤理化性质及土壤可蚀性的影响。结果表明：1）计划烧除对土壤化学性质的影响表现在土壤表层，随着土层的加深影响减弱。有机C、全N、全P在0～20 cm土层计划烧除样地显著低于未烧除样地；全K、速效P、速效K在0～10 cm土层，硝态N、pH值在0～60 cm土层显著高于未烧除样地。2）计划烧除对土壤物理性质影响也主要表现在土壤表层。土壤含水量在0～60 cm土层、容重在0～20 cm土层计划烧除样地高于未烧除样地，毛管持水量在0～10 cm土层低于未烧除样地。3）计划烧除改变了土壤表层团粒结构，减弱了土壤抗蚀能力。计划烧除使土壤粉粒、黏粒、有机碳含量在0～10 cm土层下降，沙粒在0～10 cm土层升高，土壤可蚀性因子K在0～40 cm土层增加，土壤可蚀性增强。计划烧除对云南松林土壤理化性质及可蚀性影响主要在于土壤表层，随着土层加深受到计划烧除影响越来越弱。
