林业工程中抗旱造林技术分析

Analysis of Drought-resistant Afforestation Techniques in Forestry Projects

随着全球气候变化的影响日益加剧,干旱问题在林业生产中变得尤为突出,严重影响了森林生态系统的稳定性和可持续发展。抗旱造林技术是应对这一问题的关键手段,通过改善树木的抗旱特性和引入多种抗旱技术,能够有效提高树木在干旱环境中的生存率和生长能力。该文从树木的抗旱性入手,通过分析叶片持水力、气孔调节、渗透调节、抗氧化酶系统等特征,探讨了节水灌溉、生长调节剂、保水剂等抗旱造林技术,通过对现有抗旱造林技术的系统性分析,为未来干旱地区的造林项目提供理论依据和技术指导,旨在推动林业的可持续发展并增强生态系统的抗旱能力。

With the increasing impact of global climate change,the problem of drought has become particularly prominent in forestry production,seriously affecting the stability and sustainable development of forest ecosystems.Drought-resistant silviculture technology is a key means to cope with this problem.By improving the drought-resistant characteristics of trees and introducing a variety of drought-resistant technologies,it can effectively improve the survival rate and growth capacity of trees in drought environments.In this study,starting from the drought resistance of trees,we explored drought-resistant silvicultural techniques such as water-saving irrigation,growth regulators,water retaining agents and so on by analysing the characteristics of leaf water-holding capacity,stomatal regulation,osmotic regulation and antioxidant enzyme system.By systematically analysing the existing drought-resistant silvicultural techniques,provides theoretical bases and technological guides to the future arid-area silvicultural projects with the aim of promoting the sustainable development of forestry and enhancing the drought-resistance of the This study provides theoretical basis and technical guidance for future afforestation projects in arid areas,aiming to promote the sustainable development of forestry and enhance the ecosystem’s drought resistance.
