Based on research into control area of forest firebreak belt,the paper gave results as follows:①A suitable control area would be favorable to prevent and control fire and gave full play to usual eco—economic function of the forest stand.
通过对森林防火林带控制面积的探讨得出如下结论:①合适的森林防火林带控制面积有利于预防和控制森林火灾,充分发挥目的林分正常的生态经济功能;②森林可燃物类型及火险等级是确定控制面积的主要因素;③林带控制面积要考虑森林火灾的扑救能力,扑救能力越强,控制面积越大;④目的林分的生态经济价值对林带控制面积起约束作用,林分的生态经济价值必须远大于林带的建设成本;⑤法定的森林火灾程度等级是控制面积参考的基数,林带应尽量使林火控制在不成灾的水平。
This paper shows that if,instead of control points,control lines and control planes are used,more effective tools for the design of free-form shapes will be obtained.
用控制线和控制面来代替控制顶点来确定曲线曲面的形状,从而得到更有效灵活的方法来设计自由曲线曲面的形状。
