Abstract

According to field investigation of 16 sampling plots and 256 sampling squares of Picea crassifolia community in the Qilian Mountains, Gansun Province, this paper analyzed the biodiversity of families and genera flora of Picea crassifolia community. The results show that 96 species of advanced plants belong to 25 families and 52 genera. Among them, 31 genera, 62.6% of the total, belong to temperate zone, which show that Picea crassifolia community has the temperate zone characteristic. However, the number of species, families genera of different forest types changes with altitude. The maximum families and genera richness appear in mixed forest of Populus davidiana and Picea crassifolia; while maximum species richness appears in mixed forest of Sabina przewalskii and Picea crassifolia.
