白蚁危害程度评价探讨

Discussion on the evaluation of termite damage degree

我国白蚁种类繁多,分布广泛,危害严重。对白蚁危害的程度进行科学评价是白蚁防治工作的重要内容之一。本文立足于我国目前白蚁危害评价体系现状,结合国家标准《白蚁危害评定标准》编制工作,对房屋建筑、园林植被、水利工程中白蚁危害种类、危害方式、蚁害检查方法、危害程度划分依据等方面进行分析研究,提出在白蚁危害评定工作中,应综合考虑白蚁种类、巢群密度、白蚁危害对象、危害范围、潜在风险等因素,建议将房屋建筑、园林植被和水利工程白蚁危害程度划分为3个等级。

The termites distribute widely in China,and cause serious hazards. The scientific evaluation of termite damage degree is one of the important contents of termite control. Based on the current condition of termite damage evaluation system in China,and in combination with the compilation of the national standard ＂Standard for termite damage evaluation ＂,this article analyzes the termite species found in buildings,landscape plants and water conservancy projects,their ways of damage,the inspection methods of termite damage,the demarcation criterion for the termite damage degree and so on. This article proposes that when the degree of termite damage is evaluated,the species of termite,the population density,the damaged objects,the range of hazards,the potential risk and other factors should be taken into consideration,and the degree of termite damage to buildings,landscape plants and water conservancy projects are suggested to be ranked by three grades.
