【摘要】 为研究温带山地森林生态系统植物群落对不同程度干扰的响应,本研究以北京市松山国家级自然保护区蒙古栎群落为研究对象,探讨不同干扰程度下的植物种类多样性和土壤有机质含量的变化规律。结果表明:草本多样性对群落的干扰最为敏感,一定程度的干扰下,蒙古栎林内灌木和草本多样性随干扰程度先减小后增加;同时,轻度退化土壤有机质含量随深度的加深,呈递减的趋势;中度退化土壤有机质含量,随深度的加深,也呈递减趋势,但在20~40 cm处出现增长;重度退化土壤有机质含量,随深度的加深,呈先减少再增长的趋势。更多还原

【Abstract】 To study the response of forest ecosystems in temperate mountain plant communities to different degrees of interference, the study of Beijing Songshan National Nature Reserve Quercus mongolica community for the study, to explore variation of plant species diversity and soil nutrients under different levels of interference. The results show that: the interference of herbaceous communities most sensitive to diversity, under a certain degree of interference, the degree of interference with diversity Quercus mongolica community shrub grass decreased first increase; Meanwhile, lightly degraded soil organic matter content with depth deeper, showing law of diminishing; moderately degraded soil organic matter content, with depth deepens, showed a decreasing trend, but have increased in the 20~40 cm; heavily degraded soil organic matter content, with depth deepens, was the first to reduce re-growth trend.更多还原
