摘　　要：The growth of Nyssa yunnanensis saplings in Guanping area was monitored in 2011, 2013 and 2015. The results showed that the average basal diameter growth rate during 2013-2015 was higher than that during 2011-2013, and that during 2009-2011 was lowest; the average height growth rates in the durations of 2011-2013 and 2013-2015 were basically the same, and that during 2009-2011 was relatively slow; the growth of diameter at breast height（DBH） in the duration of 2013-2015 was significantly higher than that in the duration of 2011-2013. Comprehensive and better nature-returning work, as well as long-term and stable funding, is required for the protection of Nyssa yunnanensis.通过2011年、2013年和2015年对种植在关坪区域的云南蓝果树幼树生长情况的监测,认为2013~2015年时段内的平均基径增长速度高于2011~2013年时段,2009~2011年时段内的增长速度最慢;平均高度增长在2011~2013和2013~2015年2个时段内基本相同,2009~2011年时段内增长相对较慢;胸径变化速度2013~2015年明显高于2011~2013年。建议要全面做好云南蓝果树的野外回归,需要有长期、稳定的经费投入。
