摘要: 根据对生物分布地预测模型和软件发展现状的分析和总结,本研究在PSDS1.0的基础上提出并实现一个基于GIS且具有多个代表性模型的生物分布地预测系统(PSDS2.0)。PSDS2.0系统继承了1.0的环境包络和聚类包络模型,进一步引入了限制因子包络、马氏距离、支持向量机等新模型,并针对本领域中模型比较与选择的难点增加了迭代交叉验证的多模型选择功能。系统还实现了灵活定制和评估伪负样本的功能,通过用只需要正样本的I类模型预测的结果对随机产生的伪负样本进行评估,减小其落入适宜地区的概率,进一步提高需要正负样本的II类模型的准确率。GIS功能在PSDS2.0中也得到加强,被应用于数据准备及结果分析等重要环节。文章最后以白冠长尾雉(Syrmaticus reevesii)为例,运用PSDS2.0系统预测其在中国范围内的潜在分布地,并对各种模型的预测结果进行评估和比较。
