本文针对砒沙岩地区沟道人工植物柔性坝这一治水治沙的新设想，依据质量守恒及力学定律，导出了水在树木丛中流动的基本微分方程；其后对它们进行了数值处理，得到了通用形式及离散关系；最后对基本方程的结构形式进行了有益的探讨
In this paper, aiming at the new concept of channel artificial plant flexible dam in Shaheyan area, based on the principle of conservation of mass and laws of mechanics, the basic differential equations of water flowing in the trees are deduced. Afterwards, Get the general form and the discrete relation; At last, it makes a useful discussion on the structure of the basic equations
