Utilization of wild plant resource in the Miao nationality resident regions of Zongdi Village in Mashan area,Guizhou Province

The utilization of wild plants in the Miao nationality resident regions of Zongdi Village of Guizhou Province was investigated through ethnobotanical research methods.It was found that 83 species belonging to 42 families were commonly used by local people.Compositae(12 species),Liliaceae(12 species),Gramineae(5 species) and Rosaceae(5 species) were the four important families which accounted for 14.46%,7.23%,6.02% and 6.02% of total species respectively.The main use parts of wild plants included root(7 species),stem(33 species),phloem(3 species),leaf(26 species),flower(2 species),fruit(19 species),bud(5 species) and whole plant(16 species),accounting for 8.43%,39.76%,3.61%,31.33%,2.41%,22.89%,6.02% and 19.28% of total species respectively.These wild plants were classified as food plant(26 species),medicinal plant(37 species),building material plant(12 species),forage plant(9 species),craft plant(6 species),fiber plant(5 species),dry plant(3 species),oil plant(2 species),spirit plant(1 species) and entertainment plant(1 species),accounting for 31.33%,44.58%,14.46%,10.84%,7.23%,6.02%,3.61%,2.41%,1.20% and 1.20% of total species respectively.There were 6 species(7.23%) with three uses and 12 species(14.46%) with two uses.The research suggests that there are close relationships between the utilization of these wild plants and their biological characteristics,karst environment and Miao nationality culture,which also need further research.
