Among them, a phenomenon in which drought has a significant impact on the ecosystem can be defined as an ecological drought. In this study, the Ecological Drought Condition Index-Vegetation (EDCI-veg) was newly proposed to quantitatively evaluate and monitor the effects of meteorological drought on vegetation. A copula-based bivariate joint probability distribution between vegetation information and drought information was constructed, and EDCI-veg was derived from the joint probability model. Through the proposed EDCI-veg, it was possible to quantitatively estimate how much the vegetation condition was affected by the drought, and to identify the timing of the occurrence of the vegetation drought and the severity of the vegetation drought. In addition, as a result of examining the applicability of the proposed EDCI-veg by comparing past meteorological drought events with the corresponding vegetation conditions, it was found that EDCI-veg can reasonably monitor vegetation drought. It has been shown that the newly proposed EDCI-veg in this study can provide useful information on the ecological drought condition that changes with time. On the other hand, the ecological drought analysis based on the type of land cover showed that the response of vegetation to meteorological drought was different depending on the land cover. In particular, it was revealed that the vegetation inhabiting the forest has a relatively high resistance to meteorological drought.<\/jats:p>","DOI":"10.3390\/rs15020337","type":"journal-article","created":{"date-parts":[[2023,1,6]],"date-time":"2023-01-06T02:20:30Z","timestamp":1672971630000},"page":"337","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Ecological Drought Condition Index to Monitor Vegetation Response to Meteorological Drought in Korean Peninsula"],"prefix":"10.3390","volume":"15","author":[{"given":"Jeongeun","family":"Won","sequence":"first","affiliation":[{"name":"Division of Earth Environmental System Science (Major in Environmental Engineering), Pukyong National University, Busan 48513, Republic of Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6244-6612","authenticated-orcid":false,"given":"Sangdan","family":"Kim","sequence":"additional","affiliation":[{"name":"Division of Earth Environmental System Science (Major in Environmental Engineering), Pukyong National University, Busan 48513, Republic of Korea"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,6]]},"reference":[{"key":"ref_1","first-page":"561","article-title":"Application of SAD curves in assessing climate-change impacts on spatio-temporal characteristics of extreme drought events","volume":"30","author":"Kim","year":"2010","journal-title":"KSCE J.
