Major results were summarized as follows:(1) A total of 58 tree species from 53 genera in 36 families among which 8 species were Rosaceae, 5 species were Liliaceae, 5 species were Eriaceae, 3 species were Ranunculaceae, 3 species were Compositae, 2 species were Cupressaceae, 2 species were Caprifoliaceae, 2 species were Umblliferae, and other 28 tree species were only one receptively. These were recorded in the 8 plots of the A. georgei var. smithii forest;(2) Number of families, genera, species and Margalef index correlated negatively with altitude (P.05), with a peak at 3600 m.(3) Shannon-Wiener index correlated negatively with altitude (P.01), and maintained stable at the altitudes between 3700~4100 m, evenness with altitudes, however, this trend was insignificant.(4) Jaccard index increased sharply with increasing altitude at the altitudes between 3600~4100 m, and was lower between different vegetation types at the altitudes between 4100~4200. Cody index β(subscript c decreased with an increasing altitude, but there were 2 troughs between 4000~4100 m and 4200~4300 m.(5) Maximum tree height H(subscript max and HH(subscript max=37 mcorrelated negatively with altitude (P.05); but basal area and BA BA(subscript max=5.3m^2 correlated with altitudes, however, this trend was insignificant.

One hundred and thirty four families, 578 genera and 1197 species are recorded in this area. According to the information of historical geology and natural conditions, the composition of seed plant flora and the areal-types of genera were analyzed. The results showed that its origin was rather ancient and its geographical compositions were complicated. There were many species of rare and endangered plants, e.g. Taxus chinensis var. mairei, Bretschneidera sinensis, Emmenopterys henryi, Fokienia hodginsii, Torreya grandis, Phoebe bournei, Ormosia henryi, and so on. Most of these plants had high value in economics and scientific research. According to statistics and analysis of genera in the present flora, 578 genera were divided into 14 areal-types. The ratio of tropical and temperate genera was respectively 48.6% and 49.2%, so its flora was characterized by transitional floristic elements, and in wide connection with the world.
