| Abstract: | Combine the methods of data consult,access and field survey,the resources of wild Symplocos paniculata were investigated and analyzed.The results showed that the wild S.paniculata were mainly distributed in the areas with mountain yellow-brown soft and alpine meadow soil at an altitude above 1 200 m,which depended on root breeding and birds for their reproduction.The illumination intensity,topsoil water retention and topsoil fertility were the major factors affecting the natural distribution.The yield per plant of S.paniculata in this region has significant difference,and the max seed yield of single plant is 20 kg and the variation coefficient of 59.14%.The crown,tree height are the main factors for the tree structure for the yield per plant of S.paniculata. |
