未来气候背景下的我国野生薤白潜在适生区预测
Prediction of Potential Suitable Areas of Wild Allium macrostemon in China under Future Climate
摘要
Abstract
Objective:To understand the main climatic and ecological factors affecting the growth of Allium macrostemon,and to predict its potential suitable areas,so as to provide reference for expanding the introduction and cultivation of Allium macrostemon and protecting wild resources effectively.Methods:The MaxEnt model and ArcGIS technology were used to analyze 326 loci on the geograph-ic distribution of Allium macrostemon in China,and the main environmental factors affecting the geographic distribution were selected.Based on the current distribution situation,the potential spatial distribution pattern of Allium macrostemon under different climatic condi-tions in 2041 to 2060 and 2061 to 2080 was predicted.Results:Under the current climate,the suitable growth area of Allium macroste-mon was 416.57×104 km2,and the high growth area was mainly distributed in Shaanxi,Hunan,Anhui and other provinces.Annual precipitation,average annual temperature,precipitation of the wettest month and average temperature of the driest season were the main environmental factors limiting its distribution.In different climatic periods in the future,the overall suitable areas of Allium macrostemon will migrate northward.With the increasing of global climate temperature,the potential optimum habitat of Allium macrostemon will be decreasing gradually.Conclusion:This study shows that climate change has an important impact on the habitat of Allium macrostemon,and it is recommended to strengthen the attention and protection of wild resource species of Allium macrostemon.关键词
