%X Nutrient concentrations and contents in leaves of broadleaved Elaeocarpus sylvestris, Castanopsis hystrix, Ormosia pinnata, Michelia macclurei, Camellia semiserata, Liquidambar formosana, Castanopsis fissa, Mytilaria laosensis and Cinnamomum camphora seedlings were studied. Leaf N, P and K concentrations in Ormosia pinnata, Castanopsis fissa and Cinnamomum camphora were higher than those of other tree species, and leaf N, P and K contents in Camellia semiserata, Castanopsis fissa and Cinnamomum camphora were higher than those of other tree species. Mean leaf nutrient concentration in upper crown and lower crown of 9 tree species was N 16.67 and 17.09 g.kg-1, P 1.29 and 0.84 g.kg-1, K 11.77 and 6.65 g.kg-1, respectively. Mean leaf nutrient content in upper crown and lower crown of 9 tree species was N 0.871 and 1.069 g.m-2, P 0.065 and 0.052 g.m-2, K 0.608 and 0.426 g.m-2, respectively. Leaf P and K concentrations and contents in the upper crown were generally higher than those of the lower crown. From the view of nutrient contents, mixing Camellia semiserata with other tree species, mixing Castanopsis hystrix or Mytilaria laosensis with Elaeocarpus sylvestris, Liquidambar formosana, Ormosia pinnata, Castanopsis fissa, and Cinnamomum camphora, and mixing Michelia macclurei with Castanopsis fissa and Cinnamomum camphora were suitable.
