摘要:
【目的】通过2015至2017年对四川省凉山彝族自治州盐源县平川镇小高山林业有害生物普查,发现林业有害昆虫红脂大小蠹近年来对该地区的云南松林造成一定的危害,本文通过建立有害昆虫风险评估量化体系,针对盐源小高山林业有害昆虫红脂大小蠹进行风险性评估。【方法】本文采用多指标综合评价法,借鉴《四川省林业有害生物普查技术方案》中系统分析方法的风险分析方法,通过对影响有害昆虫分布、传入定殖扩散、潜在危害、受害寄主经济重要性、危险性管理难度这五个因素进行分析,提出有害昆虫风险评估量化指标体系,使用各种数据统计方法得出最终的评价值。【结果】盐源县小高山红脂大小蠹的风险性分值为2.05分,为高度危险发生害虫。【结论】本文通过查阅大量参考文献,使用所构建的评估系统在“有害昆虫”的地理分布方面充分考虑,分别考虑到该有害昆虫在“国外、国内和盐源小高山”的分布对综合评价值R的影响,针对于林业有害昆虫的风险评估具有较强的科学依据;本文通过对盐源小高山林业有害昆虫红脂大小蠹运用所构建的“盐源小高山林业有害昆虫红脂大小蠹评估系统”进行评估,评估结果与刘海军等2005年在《北京地区红脂大小蠹、美国白蛾和锈色粒肩天牛风险评价》中得出的结论“红脂大小蠹的量化评估值为2.46,为一种高度风险森林有害昆虫”(刘海军等,2005)进行对比,评估结果没有太大差异,进一步说明,本文所构建的“盐源小高山林业有害昆虫红脂大小蠹评估系统”具有较强的实践意义。

Risk assessment of forestry harmful insect Dendroctonus valens in Xiaogaoshan,Yanyuan County

Abstract:
【Aim】Based on the general survey of forest pests in Xiaogaoshan, Pingchuan Town,Yanyuan County, Liangshan Yi Autonomous Prefecture, Sichuan Province from 2015 to 2017, it was found that the harmful insect Dendroctonus valens caused certain harm to the pinus yunnanensis forest in recent years.In this paper,a quantitative risk assessment system for harmful insects was established to conduct a risk assessment of D. valens in Xiaogaoshan,Yanyuan County.【Method】This paper uses a multi-index comprehensive evaluation method and draws lessons from the risk analysis method of the systematic analysis method in the Technical Plan for the Survey of Forestry Pests in Sichuan Province. Based on the analysis of the five factors that affect the distribution of harmful insects, afferent colonization and diffusion, the potential harm, the economic importance of the victim host and the difficulty of risk management, a quantitative index system for risk assessment of harmful insects is proposed, and the final evaluation value is obtained by using various data statistical methods.【Result】The risk score of D. valens in Xiaogaoshan, Yanyuan County was 2.05, which was a high risk pest.【Conclusion】Based on a large number of references, this paper fully considered the geographical distribution of "harmful insects" by using the evaluation system, and considered the impact of the distribution of harmful insects in "foreign, domestic and Xiaogaoshan, Yanyuan County" on the comprehensive evaluation value R, which has a strong scientific basis for the risk assessment of forestry harmful insects. In this paper, the “Xiaogaoshan forestry harmful insect Dendroctonus valens evaluation system” was used to evaluate forestry harmful insect D. valens in Xiaogaoshan, Yanyuan County. Evaluation result is not much different from the research results of Liu Haijun et al in 2005, which found that D. valens is a high risk forest pest, quantitative evaluation value 2.46. Further explanation, the “Xiaogaoshan forestry harmful insect Dendroctonus valens evaluation system” constructed in this paper has strong practical significance.
