摘要我国人均水资源占有量很少，社会经济越发展，人民生活水平提升得越快，淡水资源和人均需求之间的矛盾也就越大，而且确保饮用水的水质安全面临着更大的挑战，要求更高。随着近几年饮用水源地事故的频繁发生，群众对水源地水质安全也愈加重视，苏州的饮用水取水口基本都在太湖，如果太湖水质一旦被污染，会直接影响到苏州人民的饮用水安全。所以，苏州工业园区开辟了阳澄湖水源地，形成“双水源”供水格局，保障园区人民的饮用水安全。本文主要通过近几年对阳澄湖的监测，分析苏州工业园区阳澄湖水源地的水质安全情况，得出通过政府近几年努力，苏州工业园区阳澄湖水源地水质类别总体保持稳定，富营养化指标总体又不显著下降，仍需持续关注。本论文还分析影响水源水质的各类因素，如降水和面源污染，大气中的氮氧化物沉降问题等。不仅如此，文章中比较了上游来水水质和水源地水质从而得出来水水质的影响因素。同时对于阳澄湖最近的特殊情况作出了分析。最后针对阳澄湖现状，提出了合适的预警体系，给予保障苏州工业园区阳澄湖水源地水质工作一定的参考。关键词：饮用水源地，水质安全，预警，保护措施PAGE\*MERGEFORMAT51AbstractChina’sfreshwaterresourcespercapitaisextremelyscarce.Withtherapiddevelopmentofsocialeconomy,people’slivingstandardsgraduallyimprove,thedemandforfreshwaterresourceisbecomingmoreandmorebig,especiallyputsforwardhigherrequirementsonthewaterqualitysecurityofdrinkingwater.Asthesourceofdrinkingwaterinrecentyears,accidentsoccurfrequently,thecrowdismoreandmoreattentiononwaterqualitysecurity,basicinTaihuLake,SuzhouwaterintakeifthepollutionofTaihulakewaterquality,thewholeSuzhoupeople'sdrinkingwaterwillbeaffected.So,Suzhouindustrialpark,openedtheYangchengLakewatersource,formapatternofdualwatersupply,thedrinkingwatersafetyofpeopleinthepark.ThispapermainlythroughthemonitoringofYangchengLakeinrecentyears,theanalysisofSuzhouindustrialpark,YangchengLakewatersourcewaterqualitysafetysituation,itisconcludedthatthroughthegovernmenteffortsinrecentyears,Suzhouindustrialpark,YangchengLakewaterqualitycategoriesgenerallystable,eutrophicationindexwithoutasignificantreductioninoverall,stillneedtocontinuetofocuson.Thispaperalsoanalyzedtheprecipitationandtheinfluenceofnon-pointsourcepollutiononwaterquality,atthesametimecombinedwithnitrogenfromtheatmosphere,analyzedtheatmosphericnitrogendepositionontheeffectofammonianitrogeninthewater.Andalsoforinfluenceofcomingwaterfromtheupperstreamcomingwaterandwaterqualityanalysis.AtthesametimemadeananalysisforthespecialcaseofYangchengLakerecently.Finally,inviewofthepresentsituationofYangchengLake,andputsforwardappropriateearlywarningsystem,protectionofSuzhouindustrialpark,yangchenglakewaterqualityreferencework.Keyword:drinkingwatersourcearea,watersecurity,safetywarning,protectionmeasuresPAGE\*MERGEFORMAT51目录摘要............................................................................................................................................IAbstract.....................................................................................................................................II目录..........................................................................................................................................III第一章绪论...............................................................................................................................11.1研究背景及意义..............................................................................................................11.2拟采取的研究方法和技术...
