简介:啮齿类动物是散布了瘟疫,和Spermophilusdauricus的主要主人动物(S。dauricus)是在诺思中国的最普通的啮齿类动物。在这研究,啮齿类动物密度调查从4月在瓷器吉林省被执行到2005年8月。我和semivariogram弄弯的Morans被用来调查采样数据的空间分发特征。我们发现空间自相关索引低、失败产生一条有意义的semivariogram曲线。在这种情况中,通常使用内插器,例如kriging,不对在学习区域上印射密度合适。然而,三明治模型,基于空间成层的异质,能被用于我们的数据。我们的结果证明土壤和土地使用的类型显著地影响了啮齿类动物密度的分发,并且这些变量的交互效果独自比每个变量的强壮得多。估计三明治的啮齿类动物密度地图证明那啮齿类动物密度在吉林省从东南增加了到西北。最后,用三明治模型的啮齿类动物密度调查的一个框架被介绍。
