We investigated to analyze the ecological changes of plants in the Wolyoung wetland conservation area from August 2014 to September 2015. The vascular plants investigated in the 2011 literature are 153 taxa(50 families, 110 genera, 136 species, 16 varieties, 1 form). Field survey in 2015 was 208 taxa(66 families, 145 genera, 182 species, 1 subspecies, 23 varieties, 2forms). In the 2015 survey, most vascular plants were composed of dicotyledons. Also, naturalized plants of vascular plants were investigated as 8 taxa(3.85%). Gramineae was the most abundant in 21 taxa, Rosaceae and Compositae were found in 15 taxa. In 2015, the number of vascular plant increased in 55 taxa, and the naturalization plant was increased in 5 taxa than 2011. The reason why number of vascular and naturalization plant increased is disturbance for increase of visitors, wetland succession, landization, etc. The Wolyoung wetland consists of four small wetlands. The vascular plants of Wolyoung wetland were investigated as follows: 1 wetland 152 taxa, 2 wetland 102 taxa, 3 wetland 89 taxa, and 4 wetland 99 taxa. Among the life forms of vascular plants, the Dormancy form showed a high distribution of G(Geophyte) in 2011 and a high distribution of H(Hemicryptophytes) in 2015. Among the Propagation form, Radicoid form showed the type of R5(taxa without lateral spreading) > R3(taxa with the smallest lateral spread rhizome) > R2,3 in both 2011 and 2015. Among the Propagation forms of vascular plants, the Disseminule form was investigated in order of D4(plants disseminated by gravity) > D1(plants disseminated by wind and water) > D2(plants disseminated by animals and human) in both 2011 and 2015. Growth form of vascular plants was surveyed in order of e(erect form) > t(crowding form) > ps(rosette-erect form) in both 2011 and 2015. Especially, the increase of crowding form(t) and branching form(b) reflects the characteristics of Gramineae and Cyperaceae that are major dominant Family of wetland vegetation, and gradually shows the typicality of wetland vegetation.
