【摘要】 以中亚热带南缘的福建省西部典型退化红壤地域一系列不同封育阶段的森林群落为研究对象,对退化生态系统植被过程中群落物种多样性进行了研究。运用几种多样性指数测定的结果一致地显示了植被恢复过程中物种增长的趋势,但指数值相对较小,变动幅度不大,与保存良好的福建省建溪流域甜槠林群落物种多样性的比较结果显示,该地域物种多样性总体上不高,增长速度较慢。通过对该退化地区森林物种动态的研究,揭示以封育为主要方式的植被恢复过程早期的森林群落发展规律,为采取适当的人工促进措施加速植被恢复提供了理论依据。更多还原

【Abstract】 The research on restoring the structure and function of degraded ecosystem is of great significance in theory and practice.In this paper,the species diversity of closed forest communities in the degraded regions in the southern mid-subtropics was analyzed through studying a series of communities with different ages.All results indicated that richness and diversity increased with the restoration time,but the index values were in a low level,with a relatively small fluctuating range,which reflected the low speed of increase.The studies on dynamics of species diversity of the closed forest communities in a typical degraded region affirmed the active effect in vegetation restoration brought by closing management,and offered some useful principles for creating a benign restoration mechanism.更多还原
