The composition of seed plants in the plot of Guiyang forest farm was investigated by typical sampling method, the diversity and floristic composition characteristics were analyzed. The results showed that there were 346 species of seed plants in Guiyang Forest Farm, belonging to 104 families and 202 genera. From the perspective of family level, single-species families were the most, with a total of 45 families, accounting for 43.27% of the total families, followed by oligospecies families, accounting for 36.54% of the total families, and large families were the least, only 7 families, accounting for 6.73% of the total families. At the genus level, there are 135 genera of single species, accounting for 66.83% of the total genera. There are 46 tropical geographical elements, accounting for 44.2% of the total number of families, and 20 temperate elements, accounting for 19.2% of the total number of families, indicating that the geographical elements of the family have strong tropical properties. The distribution type of genera, tropical distribution type 77 genera, accounting for 38.1% of the total number of genera, temperate distribution type 93 genera, accounting for 46.0% of the total number of genera, indicating that there is a temperate zone. And subtropical properties. There are 4 genera endemic to China in this survey, and no families endemic to China were found. At the same time, seven kinds of resource plants in the forest farm were introduced, and suggestions for the protection and development and utilization of plant resources were put forward. %K 种子植物， %K 植物区系， %K 应用价值， %K 桂洋林场
