拉萨南北山树种选择与典型造林模式

Tree Selection and Typical Afforestation Model of South-North Mountains in Lhasa

本文旨在科学推进拉萨南北山绿化工程。通过调查拉萨南北山区域10个典型林地(林木)立地条件和林木生长状况,分析现有成功树种的生态习性,筛选出拉萨南北山适生树种。结果表明:20余个具有抗旱耐寒耐瘠薄特性的树种适宜拉萨南北山立地条件。为集约利用土地、实现拉萨南北山绿化生态与景观功能、推动拉萨南北山造林绿化工程高质量发展,编制典型造林模式6种。

The paper aimed to promote the greening project of South-North Mountains in Lhasa in a scientifically informed manner.This was achieved through an investigation of the site conditions and growth status of trees in ten representative forested areas within the South-North Mountains.The analysis focused on the ecological characteristics of tree species that had demonstrated successful adaptation to the region,ultimately leading to the selection of tree species suitable for afforestation in the South-North Mountains of Lhasa.The findings revealed that more than 20 tree species,characterized by their resilience to drought,cold,and poor soil conditions,were well-suited to the site conditions of the South-North Mountains in Lhasa.To efficiently utilize the available land,enhance the ecological and landscape functions of the South-North Mountains,and promote the high-quality development of the afforestation and greening project in this region,six typical afforestation models had been devised.These models serve as a foundational framework for the intensive use of land,ensuring the realization of ecological and landscape functions,and driving the sustainable development of the greening project within the South-North Mountains of Lhasa.
