초록

To elucidate occurrence patterns of naturalized plants in agroecosystems, we surveyed flora in uplands, orchards and rice paddy fields in middle regions (Gyeonggi-do and Chungcheong-do) of Korea in summer and fall from 2013 to 2015. Our results showed that there are 77 species of naturalize plants in 54 genera and 20 families of vascular plants among total 420 species occurred in the agricultural areas composing 18.3% of naturalized index. Community compositions of both native and naturalized plants were different among agricultural types.We suggested that Cerastium glomeratum Thuill., Bidens frondosa L. and Erigeron philadelphicus L. are capable of dispersal to other regions based on our results with getting to broaden distribution of naturalized plants. The mean naturalized index was the highest in the upland (25.1%) followed by in the orchard (23.0%) and the paddy field (16.1%), while the mean number of naturalized species was the highest in the orchard (21.8 species) followed by in the upland (16.6 species) and paddy field (10.3 species). The numbers of naturalized plants in the orchard were increased along with increasing size of the agricultural land and decreasing ecological area rate. In addition, the number of native species was significantly correlated with the number of naturalized species in the upland. Our results would provide useful information to manage dispersion of naturalized plants in agricultural ecosystems.
