GIS是一種對(duì)地理環(huán)境等方面數(shù)據(jù)進(jìn)行儲(chǔ)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(guān)數(shù)據(jù)與氣候、環(huán)境和社會(huì)等數(shù)據(jù)進(jìn)行整合和分析，通過(guò)統(tǒng)計(jì)學(xué)或數(shù)學(xué)模型，找到影響流感發(fā)生和傳播的風(fēng)險(xiǎn)因素，對(duì)流感的發(fā)生趨勢(shì)進(jìn)行預(yù)測(cè)和可視化預(yù)警。國(guó)內(nèi)外學(xué)者利用GIS在禽流感風(fēng)險(xiǎn)因素分析和預(yù)測(cè)等方面做了大量研究，包括對(duì)人感染H7N9流感、高致病性H5亞型禽流感、野禽流感風(fēng)險(xiǎn)因素和預(yù)測(cè)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(yīng)用研究等。這些研究對(duì)指導(dǎo)獸醫(yī)流行病學(xué)研究人員將GIS更好地應(yīng)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.
