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.展开更多
