广西国家储备林工程珍稀树种资源调查与分析

加强国家储备林工程珍稀树种资源调查与分析,对我国林业资源增长由数量型向质量型转变具有重要意义。文中在了解广西人工培育珍稀树种用材林资源现状的基础上,按照统一标准、统一方法、统一评价原则,调查广西国家储备林(一期)工程珍稀树种培育实际情况,分析珍稀树种资源种类、分布、面积、生长状况等情况。结果表明:珍稀树种培育总体保存率较高,保存面积3 318.83 hm2,占总调查面积的88.66%,其中幼树生长质量整体较好;同时,广西国家储备林工程珍稀树种资源培育存在培育技术不够成熟、珍稀树种培育面积较小、部分作业编制不合理等问题。结合实际情况,提出积极探索珍稀树种栽培技术、加强林区基础设施建设、保证多渠道资金投入、重视作业设计科学性的建议,为科学制定珍稀树种资源发展规划、规范经营和管理珍稀树种资源、有效提升国家储备林建设质量提供参考。

Investigation and Analysis of Rare Tree Species Resources in National Reserve Forest Project in Guangxi Zhuang Autonomous Region

Strengthening the investigation and analysis of rare tree species resources in the national reserve forest project is of great significance for the transformation of my country's forestry resources growth from quantitative to qualitative. Based on the investigation of the current situation of timber forest resources of artificially cultivated rare tree species in Guangxi, according to the unified standard, unified method and unified evaluation principle, this paper investigates the actual situation of rare tree species cultivation of Guangxi National Reserve Forest (phase I) project and comprehensively analyzes the species, distribution, area and growth status of rare tree species resources. The results showed that the overall preservation rate of rare tree species cultivation was relatively high, with a preserved area of 3 318.83 hm2, accounting for 88.66% of the total surveyed area. The growth quality of young trees in the overall preserved area was generally good. At the same time, there are some problems in the cultivation of rare tree species resources in Guangxi national reserve forest project, such as immature cultivation technology, small cultivation area of rare tree species, unreasonable preparation of some operations and so on. Combined with the actual situation, this paper puts forward some suggestions on actively exploring rare tree species cultivation techniques, strengthening forest infrastructure construction, ensuring multi-channel capital investment, and attaching importance to the scientific nature of operation design so as to lay a foundation for scientifically formulating the development plan of rare tree species resources, standardizing the management of rare tree species resources and effectively improving the construction quality of national reserve forest.
