In order to select the excellent provenance of Parakmeria latungensis, the young forests of 14 provenances were investigated and evaluated comprehensively using analytic hierarchy process (AHP). The results showed that there were significant differences in six traits, including tree height, diameter at breast height, crown density, leaf area, leaf color and afforestation preservation rate among different geographic provenances, showing a huge potential for improvement. The broad heritability of these six traits were 0.835, 0.811, 0.857, 0.823, 0.950, and 0.708, respectively, suggesting these traits were mainly controlled by genetic factors instead of environmental factors. The result of AHP showed that 4 provenances of P. latungensis, which derived from Shunchang of Fujian Province, Xinning of Hunan Province, Longquan of Zhejiang Province and Jiangle of Fujian Province, had the higher promotion and application value in the north of Zhejiang, while 3 provenances of P. latungensis, which derived from Longnan of Jiangxi Province, Ledong of Hainan Province and Jianfengling of Hainan Province, performed poorly in terms of growth, adaptation and ornamental characteristics.
