GIS是一種對地理環(huán)境等方面數(shù)據(jù)進行儲存、分析,、加工和呈現(xiàn)的綜合工具,。利用GIS可以把流感病例的相關數(shù)據(jù)與氣候、環(huán)境和社會等數(shù)據(jù)進行整合和分析,，通過統(tǒng)計學或數(shù)學模型,，找到影響流感發(fā)生和傳播的風險因素，對流感的發(fā)生趨勢進行預測和可視化預警,。國內(nèi)外學者利用GIS在禽流感風險因素分析和預測等方面做了大量研究,，包括對人感染H7N9流感、高致病性H5亞型禽流感,、野禽流感風險因素和預測的研究,，不同基因型病毒分布特征的研究，獸醫(yī)決策輔助應用研究等,。這些研究對指導獸醫(yī)流行病學研究人員將GIS更好地應用于禽流感防控具有幫助意義,。

ResearchProgress of Forecasting and Early Warning of AvianInfluenza Based on GIS

Geographicinformation system（GIS）is a comprehensive tool for storing，analyzing,，processing and presenting data relatedto geographic environment,，which couldintegrate and analyze the data regarding influenza cases，climate,，society andothers,，and identify all risk factors foroccurrence and spreading of influenza by use of statistics or mathematicalmodels to forecast and visually warn any trends of influenza. In recent years，a large number of studies on risk factorsanalyzing and forecasting of avian influenza（AI）had been carried out by scholars inboth home and abroad by means of GIS,，including,，studies on the risk factors andforecasting of human infection with H7N9 influenza，H5 highly pathogenic avian influenza（HPAI）and wild AI,，studies on the distributioncharacteristics of different genotypes of viruses,，as well as theapplication researches on the supporting of veterinary decision-making. Thesestudies would provide some references for veterinary epidemiologists toeffectively control AI by GIS.
