Adonis amurensis is an early spring plant in northeastern China that has great ornamental value. Understanding its potential habitat and critical environmental factors for its distribution is crucial for its application. Climate change scenarios were used to predict the suitable habitat of A. amurensis, which mainly distributed along the Changbai Mountains.
Adonis amurensis Regel et Radde is an early spring plant in northeastern China that has great ornamental value because it blooms before other plants have sprouted. It has not been used to its full potential due to environmental restrictions on its growth. It will be extremely important for its application to comprehend the possible habitat of A. amurensis and the critical environmental factors controlling its distribution under current and future climatic scenarios. In this work, two climate change scenarios of 2041-2060 and 2081-2100 were utilized to predict the suitable habitat of A. amurensis. The results showed that the suitable habitat was mainly distributed along the Changbai Mountains, with a total area of 303,090 km(2), and the potential and high-potential habitat area were 141,218 and 161,872 km(2), respectively. In the future climate scenarios, the suitable habitat of A. amurensis was still distributed along the Changbai Mountains, but the area was reduced. In ssp126 and ssp585 scenarios of 2041-2060 and 2081-2100, the area was reduced by 7.13% and 22.34% and 18.66% and 8.09%, respectively. The reduced suitable habitat was mainly located in central Heilongjiang (southeastern Xiao Xing'an Ling), central Jilin, and northeastern Liaoning. The suitable habitat was significantly influenced by precipitation, mainly affected by annual precipitation, followed by precipitation seasonality, soil surface pH, and slope. The results of this study can serve as empirical support for the artificial cultivation, ecological restoration, and long-term use of A. amurensis.
