野生和家养草食动物空间行为模型

(1)  栖息地偏好指数(,对于有蹄类动物k

植被类型i):

                     

 

式中,是研究去被植被类型i覆盖的百分率; 是在

植被类型i中被记录的有蹄类动物k的所有观测值的百分率。

指数随着偏好程度的增大,从0(完全避免)经过1.0(没有

偏好)向更高值变化。

2)完全程度的选择性( 有蹄类动物k):

             

 

式中,当所有栖息地与它们覆盖的面积成比例的被使用时,

这个指数理论上从0变化到200,这时即使在一个非常小

的地块上也能观测到。

(2)  在两种有蹄类动物jk之间的栖息地重叠率

()为:

             

 

式中,指数描述了一个重叠的百分比,它从0(没有重叠)

变化到 1(完全重叠)。
