| Abstract: | Picea aurantiaca var. retroflexa is one of the constructive species and dominant species of needle leaf forests in Jiuzhaigou Valley Nature Reserve. The quantitative and qualitative methods are used to analyze population of Picea aurantiaca var. retroflexa in Jiuzhaigou Valley Nature Reserve. The results are shown that Picea aurantiaca var. refroflexa is spindle structure and the population is a increasing type, while increasing rate is lower. The population has the characteristics of constant changing. |
