松材线虫病疫木清理风险防控对策——基于柳城县凉水山林场分析

Risk Control Measures for Clearing Pine Wood Nematode Infected Woods--A Case Study of Liangshuishan Forest Farm in Liucheng County

文章主要介绍柳城县凉水山林场松材线虫病的发生概况和疫木清理风险防控对策的研究及应用。分析柳城县凉水山林场松材线虫病疫木清理的可行性、效益性,提出松材线虫病疫木在清理过程中存在疫木流失风险、火灾隐患和疫情传播风险,并从疫木采伐、运输、加工、火灾隐患、人为失误、管理等六方面提出风险防控措施,介绍采伐—运输—加工—树种改培的疫木清理全过程监管方式。认为在做好风险防控的前提下可以降低松材线虫病疫木清理风险,通过树种改培可以减少疫木防治成本,增加林地单位面积产出,以此说明柳城县凉水山林场松材线虫病疫木清理具备可行性和效益性。为其他地区治理松材线虫病提供参考。

This article mainly introduces the occurrence situation of Pine wood nematode in Liangshuishan Forest Farm in Liucheng county,as well as the research and application of the risk control measures for clearing infected woods.Analyzes the feasibility and efficiency of measures for clearing infected woods.Points out the loss risk,fire risk and spread risk in disposal of infected woods,and puts forward risk control measures from six aspects:logging,transportation,processing,fire hazard,human error and management.Presents the supervision method in the whole clearing process:logging-transportion-processin-tree species improvement.The risk of clearing infected woods would be lowered under the good control measures.The control cost would be reduced and the output per unit area of forest land would be increased by tree species improvement.So it is feasible and profitable to clear the Pine wood nematode infected woods in Liangshuishan Forest Farm in Liucheng county.The results can provide reference for the control of Pine wood nematode in other areas.
