摘要
对张丽萍等建立的流域沟壑密度理论极值圆形数学模式进行了更正。鉴于更正的模式又与实际相矛盾，又推导出更符合实际的正六边形数学模式。
Zhang Liping's circular mathematical model of theoretical maximum of gully desity is corrected, and there is a larger difference between the corrected model and reality. Therefore, a regular hexagon mathematical model of theoretical maximum (D) of gully density is reckoned. The new model conforms more to the reality.
