联合 GIS 措施和统计方法，这份报纸选择地文学的因素和气候的因素在 lRGR 在人口密度上学习影响力量和它所有因素的功能的形式。另外，这份报纸与影响人口密度分发的因素在 lRGR 模仿人口密度分发的地位。调查结果显示下列情形：(1 ) 所有自然因素在 lRGR，而是影响程度和形式在人口密度的空间模式上有影响是相当不同的。地文学的因素和交通网络密度在人口密度上有大影响，当象温度和降水的如此的因素几乎没在人口分发上有小影响时。在人口密度和交通网络密度之间的关系假定否定、积极的线性关联趋势，当水系统密度和斜坡的影响看起来独立是指数的函数和对数函数时。(2 ) 人口在整个 lRGR 被散布并且当因为自然条件的影响的不可分的散布和本地集中，呈现如此的特征。因此，一条高人口密度带在 lRGR 的中间被形成了，并且一个高人口密度补丁在 lRGR 的南方形成。(3 ) 在 lRGR 在人口密度和人的活动索引(HAI ) 之间有一种好线性回归关系，它反映在场的那个人口密度罐头在 lRGR 的自然生态系统上的人工的骚乱。(4 ) 人口密度的增加导致 NDVI 索引的减少。
