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。

关键词: 沟壑密度, 理论极值, 数学模式

Abstract: 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.

Key words: gully density, theoretical maximum, mathematical model
