目的 评估2016年唐山市世界园艺博览会（世园会）期间病媒生物危害及媒介生物传染病的发生风险，以及时采取有效措施进行控制。方法 通过风险矩阵法和Borda序值法评估病媒生物危害及媒介生物传染病发生风险的严重程度。结果 2016年唐山市世园会期间病媒生物骚扰、叮咬和污染食物，引起食物中毒为高风险；病媒生物（主要为鼠）咬坏电缆，破坏电力和通讯设施为中等风险。媒介生物传染病中流行性乙型脑炎（乙脑）、疟疾、鼠疫和肾综合征出血热（HFRS）为高风险，登革热、黄热病、丝虫病、寨卡病毒病、钩端螺旋体病（钩体病）、鼠型斑疹伤寒和恙虫病为中等风险。利用Borda序值法评估病媒生物危害程度，其中病媒生物引起食物中毒为第1位，病媒生物骚扰、叮咬和破坏电力、通讯设施并列第2位；乙脑、疟疾和HFRS并列第1位，登革热、黄热病、丝虫病、寨卡病毒病、钩体病、鼠型斑疹伤寒和恙虫病并列第4位，鼠疫列第11位。结论 综合应用风险矩阵法与Borda序值法是评价病媒生物危害及媒介生物传染病发生风险水平的有效方法，具有推广应用价值。

Objective To assess and prevent the risks caused by vectors and the vector-borne disease during 2016 International Horticultural Exposition. Methods Judging the hazard caused by vectors and the risk classification of vector-borne diseases by risk assessment index matrix method and Borda sequence value method. Results It was high risk for the vector biting and infestation and food poisoning caused by vectors, it was middle risk for the cable damage and communication and power facility disruption. The prevalence of Japanese encephalitis (JE), malaria, plague, and hemorrhagic fever with renal syndrome (HFRS) were at high risk. The prevalence of dengue fever, yellow fever, filariasis, Zika virus disease, leptospirosis, murine typhus, and tsutsugamushi disease were at middle risk. Food poisoning caused by vectors ranked the first in vector harm by Borda sequence value method, vector biting and infestation and communication and power facility disruption by vectors ranked the second. JE, malaria, and HFRS ranked the first in vector-borne diseases. Dengue fever, yellow fever, filariasis, Zika virus disease, leptospirosis, murine typhus, and tsutsugamushi disease ranked the forth. Plague ranked the eleventh. Conclusion The integrated application of risk matrix and Borda count is effective in assessing the risk levels of the hazards caused by vectors and the vector-borne disease, and therefore is worthy of wide promotion.
