基于Maxent模型的越冬白头鹤适宜生境预测
Prediction of suitable habitat for overwintering hooded cranes (Grus monacha) based on Maxent modeling
摘要
Abstract
In this study,the Maxent model was used to predict the suitable habitat distribution for the hooded crane in Anhui province and the major environmental factors affecting such a distribution based on the occurrence data of the species and environmental factors.A gap analysis was conducted on the existing nature reserves.The occurrence data were collected from the winter filed survey in 2013-2014,China Bird Report and relevant literatures published in 2011-2015.The environmental factors include climate,terrain,river system,landuse type and human disturbance.The results showed that the model evaluation results was ideal,and the major evironmental factors influencing the distribution of the hooded crane included the distance from main water source,the average minimum temperature in January,the average minimum temperature in December and the distance from main roads,with a contribution of 45.3％,21.4％,19.3％ and 7.6％,respectively.The suitable habitat for the hooded crane was mainly distributed in the upper Lake of Shengjin Lake and Caizi Lake and a small amount of the habitat was distributed along Longgan Lake,in the east bank of Wuchang Lake,and along the mainstream of Yarngtze River in its east.The total area of core suitable habitat was 45 980 hm2.The Gap analysis showed that 60.1％ of the core suitable habitat of the hooded crane was protected by natural reserves.There are 18 346 hm2 core suitable habitat uncovered by these reserves;therefore more attention shall be paid to suitable habitats outside the reserves.关键词
