补充资料：圈层结构理论
所谓%26ldquo;圈%26rdquo;，实际上意味着%26ldquo;向心性%26rdquo;，%26ldquo;层%26rdquo;则体现了%26ldquo;层次分异%26rdquo;的客观特征。圈层结构反映着城市的社会经济景观由核心向外围呈规则性的向心空间层次分化。圈层结构中，城市是圈层构造的主体。多年以前，德国的农业经济学家冯早在杜能在其《孤立国》一书中就已经指出，城市郊区的农业经济活动，农业的布局会呈圈层式分布，将会以城市为中心，围绕城市呈向心环状分布。从中心向外，分别为自由农作区、林业区、轮作农业区、谷草农作区、三圃农作区和畜牧业区。这种圈层空间结构模式被誉为%26ldquo;杜能环%26rdquo;。
