造林整地是水土保持林业措施的基本措施,其拦蓄泥沙,促进树木生长,效果显著。然而用其不当,影响治理标准。本文就鱼鳞坑工程设计,提出综合方案,将造林密度、拦蓄量,地面坡度及鱼鳞坑规格融为一体,推出计算公式,建立图解图,可供设计、施工时采用。一、造林整地的作用及意义造林整地是水土保持治坡工程中林业措施的重要组成部分,是造林的基础。造林整地就是在造林之前,按着造林密度的要求,在荒山坡上作穴状、鱼鳞坑、竹节壕、水平沟等整地形式,给树木创造优越的生长条件,提高造林成活率;尤其是在幼树没有郁闭成林之前,可代替树木控制水土流失,拦泥蓄 Afforestation is the basic measure of forestry measures for water and soil conservation, which blocks sediment and promotes the growth of trees with remarkable results. However, with its improper, affecting the governance standards. In this paper, a comprehensive plan is proposed for the design of fish-scale pit engineering. The plan of planting density, storage capacity, slope of the ground and the scale of fish-scale pit are integrated. The calculation formula is introduced and the diagram is provided for design and construction. First, the role and significance of afforestation and land preparation Afforestation and land preparation is an important part of forestry measures in water and soil conservation projects, is the foundation of afforestation. Before afforestation, afforestation and site preparation will create favorable conditions for tree growth and improve the survival rate of afforestation, especially according to the requirements of afforestation density, making acreage, scaly pit, bamboo trenches and horizontal ditches on the barren hillsides; Before the young trees can not stand in the forest, they can replace the trees to control soil erosion and stop mud storage
