乡村地域系统拥有城市地域无法替代的经济、社会、生态等功能。乡村的发展对国家的经济腾飞和稳定发展有着基础性的作用,有效的保障了国家的粮食安全和食品卫生安全,保持了区域的生态平衡,同时还具有多样化的居住、社会、文化价值。我国在现代化建设中有“城市优先”的倾向,致使乡村地域系统职能的失调和空间发展的失序。主要表现在:乡村经济职能和居住职能的失调;城乡产业空间布局的失序;乡村发展空间的被剥夺。城乡协调发展要求将城市与乡村看作同等重要的地域实体,只有最大程度的发挥城乡的优势才能实现共同发展。明晰乡村地域系统的职能有利于更理性地思考城乡产业布局、乡村整治的方向、乡村职能的外部性以及乡村补贴等现实的政策问题。
