Abstract:In order to understand the plant resources and flora characteristics of the Bijie karst rocky desertification area, we surveyed the wild plant resources in the study area by sampling lines and sampling methods in 2018 and 2019, and the research was conducted through methods such as specimen collection and literature review. The plant resources and flora of the district were analyzed for providing theoretical basis for karst rocky desertification control and ecological protection. The results showed that: (1) there were 721 species of 438 genera and 133 families in the study area, including 10 families, 13 genera, 16 species of pteridophytes, 7 families, 9 genera and 11 species of gymnosperms, 116 families, 417 genera and 695 species of angiosperms. Among angiosperms, there are 15 families, 75 genera, 121 species of monocotyledonous plants, and 101 families, 342 genera, 574 species of dicotyledons. There are 35 species of rare and endangered species, belonging to 14 families and 24 genera. (2) Among the classification of resource plants, there are 516 species of medicinal plants in 121 families, 339 genera and 333 species of nectar plants in 74 families, 180 genera, 75 species of edible plants in 37 families, 60 genera, 209 species of ornamental plants in 75 families, 146 genera, 89 species of fibers in 42 families, 82 genera, 59 species of starches and sugars in 21 families, 37 genera, and 132 species of aromatic oils in 25 families, 88 genera. There are 144 species of grease in 63 families, 117 genera, 22 species of resins and gums in 17 families, 17 genera, 87 species of tanning in 63 genera and 38 families and 155 species of other plant resources total in 68 families, 128 genera. (3) On the flora, the families and genera of pteridophytes are slightly differentiated. The flora of the seed plant family is divided into 9 distribution types and 9 subtypes, mainly tropical components; 15 distribution types and 20 subtypes at the genus level, temperate elements dominate at the genus level. Studies have shown that the study area is rich in plant resources, and the flora has the dual nature and transitional characteristics of temperate and tropical zones.
