13、定方方面面不不同同，环环境境科科学学从从广广义义上上来来讲讲，包包括括了了自自然然科科学学的的所所有有领领域域。当当然然，环环境境科科学学家家的的研研究重点历史以来一直是自然环境。究重点历史以来一直是自然环境。By this,we mean the atmosphere,the land,thewaterandtheirinhabitantsasdifferentiatedfromthebuiltenvironment.Modernenvironmentalsciencehasalsofoundapplicationstothebuiltenvironmentor,perhapsmore co

14、rrectly,to the effusions from the builtenvironment.在在此此，我我们们将将大大气气、土土壤壤、水水及及那那些些生生物物与与人人工工环环境境区区别别开开来来。现现代代环环境境科科学学已已经经在在那那些些人人工工环环境境中中获获得得了了应应用用，也也许许，更更准准确确的的说说，是是对对那那些来自于人工环境的流出物。些来自于人工环境的流出物。QuantitativeEnvironmentalScienceScience or,perhaps more correctly,thescientificmethod,dealswithdata,thatis

15、,withrecordedobservations.Thedataare，ofcourse,asampleoftheuniverseofpossibilities.Theymayberepresentativeortheymaybeskewed.科科学学,或或者者，也也许许更更正正确确，科科学学的的方方法法，是是对对那那些些观观察察记记录录到到的的数数据据进进行行处处理理。而而数数据据，当当然然，是是宇宇宙宙的的可可能能性性的的一一个个样样本本。他他们们可可以以是是代代表表性性的，它们也可以走样。的，它们也可以走样。QuantitativeEnvironmentalScienceEven if

16、 they are representative,they willcontain some random variation that cannot beexplained with current knowledge.Care andimpartialityingatheringandrecordingdata,aswell as independent verification,are thecornerstonesofscience.即即使使他他们们是是具具有有代代表表性性的的，他他们们也也可可能能包包含含一一些些个个我我们们当当前前知知识识无无法法解解释释的的一一些些随随机机变变量量

17、。在在收收集集和和记记录录数数据据过过程程中中细细致致认认真真和和客客观观中中立立，以以及独立核实，是科学的基石。及独立核实，是科学的基石。When the collection and organization of datarevealcertainregularities,itmaybepossibletoformulateageneralizationorhypothesis.Thisismerelyastatementthatundercertaincircumstancescertainphenomenacangenerallybeobserved.当当对对数数据据的的收收集集和和

18、整整理理表表明明了了一一定定的的规规律律的的时时候候，有有可可能能形形成成一一个个通通则则或或者者假假设设。这这只只是是一一个个陈陈述述，即即在在特特定定的的环环境境下下通通常常可可以以观观察察到到特特定定的的现象。现象。Many generalizations are statistical in thattheyapplyaccuratelytolargeassemblagesbutarenomorethanprobabilitieswhenappliedtosmaller sets or individuals.In a scientificapproach，the hypothesis

19、 is tested,revised,andtestedagainuntilitisprovenacceptable.很很多多通通则则是是统统计计出出来来的的，即即当当其其被被应应用用在在大大的的组组合合时时候候，他他们们是是正正确确的的，当当其其应应用用于于小小的的组组合合或或者者个个体体时时候候，他他们们就就仅仅仅仅是是一一个个可可能能性性而而已已。科科学学的的处处理理方方法法，就就是是对对假假设设进进行行测测试试，修修正正，再测试，直至其被证明可接受为止。再测试，直至其被证明可接受为止。Ifwecanusecertainassumptionsortietogetherasetofgene

21、s a tremendousconsolidationofknowledge.如如果果我我们们能能够够利利用用一一些些假假设设或或着着将将一一系系列列通通则则组组合合在在一一起起的的话话，我我们们就就组组成成了了一一个个理理论论。例例如如，当当一一个个理理论论获获得得了了长长时时间间的的认认可可后后，他他们们就就被被称称为为定定律律。如如，运运动动定定律律，描描述述了了运运动动物物体体的的行行为为，而而气气体体定定律律，描描述述了了气气体体的的状状态态。理理论论的的发发展展是是一一个个重重要要的的成成就就，因因为为它它会会产产生生巨大的知识的合并。巨大的知识的合并。Furthermore,at

23、that makes science anorganizedbodyofknowledge.而而且且，理理论论可可以以给给我我们们一一个个强强有有力力用用于于获获得得知知识识的的新新的的工工具具，因因为为它它给给我我们们指指出出到到哪哪里里去去发发现现新新的的通通则则。因因此此，数数据据的的积积累累更更多多的的是是来来自自于于系系统统性性的的对对所所需需情情报报的的猎猎取取，而而不不是是对对事事实实真真相相的的胡胡乱乱收收集集。理理论论包包括括分分类类和和概概括括，理理论论使使得得科科学学成成为知识的有机体。为知识的有机体。Logicisapartofalltheories.Thetwotyp

25、。有有2种种类类型型的的逻逻辑辑：定定性性和和定定量量逻逻辑辑。定定性性逻逻辑辑是是可可描描述述的的。例例如如，我我们们可可以以定定性性的的说说：当当进进入入到到一一个个特特定定河河流流的的废废水水量量过过高高时时候候，鱼鱼会会死死掉掉。用用定定性性逻逻辑辑我我们们不不能能鉴鉴别别什什么么是是“过过高高”，这这就就意意味味着着我我们们需需要要定定量量逻辑来做这部分工作。逻辑来做这部分工作。When the data and generalizations arequantitative,weneedmathematicstoprovideatheorythatshowsthequantitat

26、iverelationships.Forexample,aquantitativestatementabouttherivermightstatethat“whenthemassoforganicmatter entering a certain river equals xkilogramsperday,theamountofoxygeninthestreamisy.”当当数数据据和和通通则则是是可可定定量量时时，我我们们需需要要数数学学来来给给出出一一个个能能够够描描述述这这个个定定量量关关系系的的理理论论。例例如如，关关于于一一个个河河流流的的定定量量描描述述是是：当当进进入入到到一一个

27、个特特定定河河流流的的有有机机物物的的量量等等于于x公公斤斤/天天，河河流流中中的的氧氧气气的的总量是总量是y.Perhaps moreimportantly,quantitative logicenablesustoexplore“Whatif?”questionsaboutrelationships.For example,“if we reduce the amount of organicmatterenteringthestream,howmuchwilltheamountof oxygen in the stream increase?”Furthermore,theories,a

28、ndinparticular,mathematicaltheories,oftenenable us to bridge the gap between experimentallycontrolledobservationsandobservationsmadeinthefield.也也许许，更更重重要要的的是是，定定量量逻逻辑辑能能够够使使我我们们探探究究这这些些关关系系见见“如如果果.会会怎怎么么样样”的的问问题题。例例如如，如如果果我我们们减减少少进进入入到到水水体体的的有有机机物物的的总总量量，水水中中的的氧氧气气的的量量会会增增加加多多少少？。而而且且，理理论论，特特别别是是数数学

29、学理理论论，通通常常能能够够在在实实验验可可控控过过程程中中观观察察的的结结果果与与现现场场实实际际观观察察的的结结果果间间搭搭建建连连接桥梁。接桥梁。（课本注释错误）（课本注释错误）For example,if we control the amount ofoxygeninafishtankinthelaboratory,wecandeterminetheminimumamountrequiredforthefishtobehealthy.Wecanthenusethisnumberto determine the acceptable mass of organicmatterplace

30、dinthestream。例例如如，如如果果我我们们在在实实验验室室控控制制鱼鱼缸缸里里的的氧氧量量，我我们们就就能能确确定定保保持持鱼鱼健健康康所所需需要要的的最最低低氧氧量量。这这样样我我们们就就可可以以用用这这个个值值来来确确定定可可接接受受的的排排入入河河流流中中的有机物的量。的有机物的量。Given that environmental science is anorganizedbodyofknowledgeaboutenvironmental relationships,then quantitativeenvironmentalscienceisanorganizedcolle
