摘　　要：为给甘肃南部亚高山油松林中华松针蚧(Matsucoccus sinensis)防控提供理论指导,采取踏查和样地相结合的调查方法,以迭部地区白龙江沿岸9个代表性林场为对象,依据国际植物检疫措施标准(ISPM)规定的林业有害生物风险性分析程序,从油松在国内及甘肃南部的分布状况(P),中华松针蚧定殖、扩散和传入可能性(P),潜在造成危害特性(P),受害对象油松在甘肃南部的重要性(P),中华松针蚧防治管理难度(P)等5个方面,评估分析了中华松针蚧在甘肃南部对油松林的危害风险。结果为,中华松针蚧主要分布在甘肃南部迭部地区,调查的9个林场中,有1个林场(Ⅴ林场)油松林受中华松针蚧危害严重;甘南亚高山油松受危害综合风险R值为1.82,危害分险等级为中度;中华松针蚧对甘南迭部亚高山油松林造成严重危害,并且形成以Ⅴ林场为中心,分别向东部舟曲县和西部四川省若尔盖二个方向蔓延的趋势,应引起管理机构足够重视,采取合理有效的防治措施控制其扩展蔓延。To study the damage degree of Matsucoccus sinensis on Pinus tabulaeformis in the south of Gansu province and its potential diffusion risk. The damage degree of M.sinensis in southern Gansu province was evaluated by regional risk analysis of forest pest according to the risk analysis procedure of forest pest stipulated in the international standard of plant quarantine measures. The risk of M. sinensis to P. tabulaeformis in southern Gansu province was analyzed in terms of distribution in China and southern Gansu(P), possibility of introduction, colonization and spread(P), potential harmfulness(P),the importance of the victims(P) and the difficulty of risk management(P). The result showed that the integrated risk value(R) of M. sinensis in southern Gansu was 1.82, and the risk to P. tabulaeformis was moderate. According to the risk analysis princples, the risk of M. sinensis in subalpine P. tabulaeformis forest in southern Gansu province is moderate, but close to high. Due to the difficulty of controlling this pest, we should pay more attention to it and conduct measures to control its spread.
