不同气候情景下二色补血草的潜在适生区预测
Prediction of Potential Suitable Areas of Limonium bicolor Under Different Climate Scenarios
摘要
Abstract
Objective:To predict the potential suitable areas of Limonium bicolor under different climatic conditions and analyze the main environmental factors affecting the distribution of Limonium bicolor.Methods:The distribution sites of 102 wild Limonium bicolor and 56 environmental factors were collected and screened.MaxEnt model and ArcGIS analysis were used to simulate the current and fu-ture climatic conditions at different time periods,and the potential suitable distribution areas were calculated and classified.Results:The MaxEnt model was repeated for 10 times,and the average AUC value reached 0.933,indicating high prediction reliability.Under the current climate conditions,the total area of the suitable area was about 267.09×104 km2,and the suitable area was mainly distributed in the north of China,with the central part of Inner Mongolia as the core.Under future climate conditions,the habitat suitability of Limoni-um bicolor will be reduced.Conclusion:This study has certain guiding significance for the establishment of the protected area,the loca-tion of planting base and the cultivation management of Limonium bicolor.关键词
