对林区营林整地与造林技术措施分析

森林资源是决定林业生存和发展的基础,林业生态建设是森林资源可持续发展的重点,普及林区的整地、造林方法是大力发展生态林业的基本措施之一。造林场地整理是造林前改善环境条件的一道主要工序。通过整地可以改善造林的立地条件、清除灌木、杂草和采伐剩余物。在造林前后的一段时间里,增加直接投射到地面的透光度;还可以改变小地形,使透光度增加或减少。整地清除了地表植被,增加透光度,因而,在白天地表层的温度要比有植被覆盖时上升得快,整地后改变了土壤物理性,使土壤温度状况发生变化。因而,能提高造林成活率及使幼林的生长情况明显改善。整地还能保持水土、减免土壤侵蚀,同时,也有利于造林施工,提高造林质量。

Analysis of Silvicultural Site Preparation of Forest and Afforestation Technology Measures

Forest resources is to determine the basis of forest survival and development,forestry ecological construction is the focus of the sustainable development of forest resources,the popularity of the forest site preparation,reforestation methods is one of the basic measures to develop ecological forestry.Afforestation site preparation is a main process of afforestation improved environmental conditions.Reforestation site conditions can be improved by site preparation,clearing shrubs,weeds,and harvesting residues.Period of time before and after the afforestation,increase the transmittance of direct projection to the ground;can change the terrain,the transmittance increase or decrease.Site preparation to clear the vegetation to increase light transmission,thus rising fast in the daytime land surface temperature than the vegetation cover,soil preparation changed soil physical,soil temperature conditions change.Thus,to increase survival rate and make the young forest growth is significantly improved.Site preparation but also soil and water conservation,reduction of soil erosion,but also conducive to afforestation construction,improve the quality of afforestation.
