        The survey was carried out from March 2020 to December 2021. A total of 30 surveys on the distribution of plants disturbing the ecosystem were conducted by dividing the 14 towns and villages in Shinan-gun. As a result, Paspalum distichum var. indutum Shinners was the most widely distributed at 111,624m2, Solidago altissima L. was 12,478m2, and Hypochaeris radicata L. 1,803m2, which was high. Solanum carolinense L., Aster pilosus Willd. and Ambrosia trifida L. were relatively low, but it is expected that the amount of Paspalum distichum var. indutum Shinners and Solidago altissima L. will gradually expand throughout shinan-gun. As a result of comparing the distribution characteristics of plants disturbing the ecosystem in shinan-gun, Paspalum distichum var. indutum Shinners was the highest at 87.2% of the total distribution area, followed by Solidago altissima L., Paspalum distichum L., Rumex acetosella L., Ambrosia artemisiifolia and Lactuca scariola L. The main distribution habitats of Paspalum distichum var. indutum Shinners and Paspalum distichum L. are agricultural waterways and reservoirs (Dumbeom) in paddy fields. Solidago altissima L., Hypochaeris radicata L., Lactuca scariola L., Ambrosia artemisiifolia L., Aster pilosus Willd. and Solanum carolinense L. were ainly found on road borders, fields (battches), and baby swimming on pasture meadows. Major ecosystem disturbances are physical, chemical and biological depending on the plant. It is considered that the biological method to induce restoration of natural ecosystem by transplanting the native species suitable for the habitat would be effective when the distribution area is small. However, comprehensive and long-term countermeasures will be needed as long-term ecosystem restoration plans related to ecosystem disturbance removal are established.
