By the means of the sample plot survey and route survey, the wild woody ornamental plantresources in Yinjiang Yangxi Natural Reserve were counted, and specimens were collected and comparedwith literature. The results showed that there are 361 species of wild woody plants which belong to 79 fami-lies, 204 genera in Yinjiang Yangxi Nature Reserve, including 183 evergreen, 178 deciduous, 151 arbor and210 shrub. Woody ornamental plants are rich, and among them, there were more evergreen, less decidu-ous, fewer arbor and more shrubs, and 10 rare ornamental species of 10 genera and 8 families. According tothe ornamental characteristics, these plants could be divided into 6 types as follows： 79 tree type species of51 genus 31 families, 69 flower--tree species of 43genus 22 families, 66 leaf--tree type species of 42 genus24 families, 51 fruit--wood species of 29 genus 22families, 50 shadow--wood type species of 35 genus 21families in and 46 vine type of species 33 genus 19 families. Finally, some suggestions were put forward toprotect and to develop the wild ornamental woody plants resources in the reserve.
