土地覆被变化的统计模型

 

(1)    土地类型为的地块的净收益()可用下式表示:

式中,是指由土地提供的商品和服务的价格与位置特性所决定的收益;是指仅由土地的结构和位置特征所决定的成本。

(2)    土地覆被变化概率的罗杰特多项式模型:

式中,是指一个栅格单元的土地覆被从最初的类型变为类型的概率;是指土地覆被的类型数,对每个初始土地覆被类型,有土地覆被变化等式:是指该栅格沿道路到最近的、为其产品提供市场或其服务可被接受的城市;包括中途截留的(产品或服务)以及除距离之外的所有反映该点的结构和位置的变量;是系数。

(3)    沿城郊结合带的人口密度(PD)变化:

并且该模型可用对数形式的普通最小二乘法来检验:

式中,是研究区内的农村地区的最大的人口密度;是指总的距离(沿道路到富兰克林的距离加上两倍至道路的最近距离);是指该地的坡度;是系数。

(4)    非森林指数():

式中,是一个二进制变量,当栅格未被森林覆盖时,它等于1,否则即为0是指从栅格单元到多个栅格组成的溪流的距离;是括号中总的最大可能值;是指栅格数。
