Abstract
Global climate change and human activities have led to the loss and fragmentation of habitats for wild orchids in recent years. Liparis campylostalix is widely distributed in northeast China and is an important component of orchids resources in the region. In this study, the MaxEnt model, ENMTools and ArcGIS were utilized to predict the potential habitat of L. campylostalix in China based on its geographical distribution and 19 environmental factors, which will be of great significance for the utilization and biodiversity conservation of this species. The results showed that under the current climate scenario, L. campylostalix was mainly distributed in Liaoning, Jilin and Anhui provinces of China, with a total suitable growth area of approximately 3.608 million square kilometers and a distribution center located in Sichuan province. The four key environmental variables affecting the distribution of L. campylostalix were Precipitation of Warmest Quarter (Bio18), Temperature Seasonality (Bio4), Mean Temperature of Coldest Quarter (Bio11), and Mean Temperature of Driest Quarter (Bio9), accounting for 94.4% of the total contribution. Under global warming conditions in the future, the potential suitable area for L. campylostalix would show an expanding trend. It would radiate from the edge of the current suitable area to the northwest region, while the distribution center still located in Sichuan province and not changed. The results of this study could provide theoretical reference for the conservation of orchids biodiversity.
