1城镇化进程中的生态环境问题及对策——以怀化市为例（湖南城市学院谢凯华）摘要：城镇化是人类社会发展的自然历史过程，是现代化的重要标志。党的十八大以来，突出“新型城镇化”，强调以人为本、集约高效和绿色智能，把城镇化与环境保护和生态文明建设结合起来。怀化市以省域次中心城市作为现阶段发展目标，在城镇化建设飞速发展的同时，生态环境的保护日益受到关注。本文以怀化市城镇化进程中引发岩石圈、大气圈和水圈的生态环境问题为出发点，具体分析怀化市城镇化进程中，造成耕地面积减少、水土流失、大气污染、温室效应、水源污染等生态环境问题的原因，并针对造成环境污染的原因，提出相关对策，为落实怀化市委四届十次全委（扩大）会议提出的奋力实施“一极两带”和“一个中心、四个怀化”发展战略，提供相关依据。关键词：城镇化生态环境问题怀化市原因对策2AbstractUrbanizationisanaturalhistoricalprocessofthedevelopmentofhumansociety.Itisanimportantsymbolofmodernization.Sincetheeighteenparty,highlightingthenewurbanization,emphasizingpeople-oriented,intensiveandefficientandgreensmart,theurbanizationandenvironmentalprotectionandecologicalcivilizationconstructioncombined.HuaihuaCity,theprovincialcentercityasthecurrentstageofdevelopmentgoals,therapiddevelopmentofurbanizationatthesametime,theprotectionoftheecologicalenvironmenthasbeenincreasinglyconcerned.ThispaperinHuaihuacityurbanizationcausedtheecologicalandenvironmentalproblemsinthelithosphere,atmosphereandhydrosphereasastartingpoint,specificanalysisofHuaihuaCity,theprocessofurbanization,resultingincultivatedlandareareduce,soilerosion,airpollution,greenhouseeffect,waterpollutionetc.ecologicalandenvironmentalproblems,andforthecauseofenvironmentalpollution,andputsforwardrelevantcountermeasures,inordertoimplementtheHuaihuaMunicipalPartycommitteeoftheTenthPlenary(enlarged)meetingofthestrugglingtoimplementthe"twobelts"anddevelopmentstrategyof"onecenterandfourHuaihuaprovideaccordingtotherelevant.KeyWords:Urbanization;Ecologicalenvironmentproblem;Huaihua;Reason;Countermeasure3目录1引言...............................................................................................................................................42城镇化进程中存在的生态环境问题............................................................................................42.1对岩石圈层面的影响........................................................................................................42.1.1耕地面积减少........................................................................................................52.1.2水土流失................................................................................................................52.2对大气圈的影响................................................................................................................62.2.1大气污染................................................................................................................62.2.2温室效应................................................................................................................72.3对水圈的影响....................................................................................................................72.3.1水源污染................................................................................................................72.3.2酸雨........................................................................................................................83城镇化进程...
