Analysis of the Correlation Between Ecological Status and Location Environment by Cultivated Land Restoration Type of Geumgang Riverine Ecobelt

“…In other words, naturality was high in Jik-dong or Sangjang-ri located in lands adjacent to a forest. This is consistent with the result that the ratio of native species in areas near forests is higher than that of cultivated lands or lands adjacent to urbanized areas (Kang, 2020) or that the mountain type increases autogenous property and promotes habitat functionality (Son et al, 2014).…”

“…Moreover, forest area showed a positive correlation with the number of amphibian and reptile species (r = 0.853), number of butterfly species (r = 0.898), number of mammalian individuals (r = 0.924), and diversity of dragonfly species (r = 0.861), thereby showing that forest location around restored sites had a positive effect on inhabitation of wild animals. In other words, the results were similar to the studies bySon et al (2014) andKang (2020) who assessed that mountain location type most effectively contributed to habitat function in terms of biodiversity of rural areas or waterfront areas. Therefore, when purchasing land to promote and maintain biodiversity of riverine ecobelts, it is necessary to first restore abandoned paddy fields or lands near forests in order to have a positive effect.Items with significance with the cultivated land area around the sites (p < .05) were the ratio of native species (r = -0.912), number of wild animal species (r = -0.840), and diversity of wild bird species (r = -0.856) showing a negative correlation.There was a positive correlation (r = 0.912) with naturalization index, showing similar results withYou et al (2014) that, when there is a restored site located near the cultivated land, it may serve as the source of naturalized plants due to disturbance and interference by agriculture.…”
