兴安杜鹃在我国东北地区适生区预测
Prediction of potential suitable areas of Rhododendron dauricum in Northeast China based on MaxEnt model
[目的]研究兴安杜鹃在我国东北地区的适生区,为兴安杜鹃保育提供依据。[方法]基于兴安杜鹃 54 个自然地理分布信息和气候、地形、土壤三类 28 个环境变量,利用MaxEnt生态位模型和地理信息系统,对兴安杜鹃在我国黑龙江、吉林、辽宁三省的适生区进行预测,通过ROC曲线检验模型精度,采用刀切法筛选主导环境变量及其适宜值。[结果]基于主导环境变量,MaxEnt模型构建的受训者工作曲线的AUC值为 0.963,表明预测结果与兴安杜鹃实际分布地拟合度很高…查看全部>>
