slope-distance rule

The main results were as follows: 1. The mixed and fir plantations' DBH, tree height, individual volume, the timber volume are both present the same rule in the different slope: down slope middle slope upper slope.

主要研究结果如下：1.杉木-闽粤栲混交林与杉木纯林胸径、树高、出材量和蓄积量随坡位的不同均表现为下坡中坡上坡的变化规律。

It is considered that the rule to determine the dimension is as follow: The slope of upstream face would be 1: 0. 2-1: 0. 4, and that of the downstream face 1:0. 75-1: 0. 9;

初步认为确定坝体轮廓尺寸的规则如下：坝体上游边坡宜为：1∶0.2－1∶0.4，下游边坡宜为1∶0.75－1∶0.9；
