毕业论文题目凤山生态县建设的效益评价2012年5月学院（系）：林学院专业：班级：学号：学生姓名：指导教师：摘要生态建设是一项长期的、多学科、综合的系统工程，它有利于资源的合理开发、利用和保护，改善生态环境，避免掠夺式经营和滥用、浪费资源的现象，提高劳动生产率和资源利用率，实现经济和生态两个良好循环，经济、社会、生态三个效益的统一。本文依据凤山县2006-2010年间社会、生态和经济的发展变化，对凤山县5a来生态县建设的综合效益进行了评价，从生态环境、经济发展、社会进步3方面选取了具体指标，利用层次分析法（APH）原理，建立了凤山生态县建设的效益评价指标体系及其权重，并运用综合指数法计算结果。就凤山县生态化程度而言，凤山县生态建设综合指数从2006年的0.5908增长到2010年的0.6624，凤山县2006年到2010年的生态建设综合指数值都介于0.55到0.75之间，且逐年增加，说明凤山生态县建设的程度较高，而且还会越来越高，凤山县的可持续发展能力逐年增强。总的来说，凤山生态县的建设近几年来取得了显著的效果，综合效益增长势头明显，经济效益发展变化最明显；生态效益总体上处于平稳发展期。为此，需要进一步改善凤山县的生态环境，提高生态效益，使系统整体功能得到增加。通过凤山县生态建设的效益评价，进一步明确了今后一段时间内生态建设的主要任务和工作，通过生态项目的实施，进一步协调经济发展和环境的关系，凤山县必将形成经济发展、环境优美、社会环境和谐的新局面。关键词：生态县建设效益评价凤山层次分析法综合指数法IPhoenixmountainShengTaiXianbenefitevaluationofconstructionAbstractEcologicalconstructionisalongterm,multidisciplinaryandcomprehensivesystemengineering,itishelpfulforresourcetorationaldevelopment,utilizationandprotection,theimprovementofecologicalenvironment,avoidLveDuoShimanagementandabuse,wastefulphenomenon,improvelaborproductivityandresourcesutilization,andtorealizetheeconomicandecologicaltwogoodcirculation,economic,social,ecologicalthreeefficiencyunification.Basedon2006-2010yearsFengShanXiansocial,ecologicalandeconomicchanges,toFengShanXianfiveyearsShengTaiXianconstructionontheevaluationofcomprehensivebenefits,fromecologicalenvironment,economicdevelopmentandsocialprogressonthethreeaspectsofthespecificindexes,theanalyticalhierarchyprocess(APH)principletobuildthephoenixmountainShengTaiXianconstructionbenefitevaluationindexsystemandweight.Andmethodofsyntheticalindexcalculatesresults.ItFengShanXianecologicallevel,FengShanXianecologicalconstructioncompositeindexfrom0.5908in2006to0.6624in2010growth,FengShanXian2006to2010yearsofecologicalconstructionarecomprehensiveexponentvaluebetween0.55to0.75between,andincreaseyearbyyear,showstheextentoftheconstructionShengTaiXianphoenixmountainishigher,butalsowillbemoreandmorehigh,thesustainabledevelopmentoftheFengShanXianabilityenhancementyearbyyear.generallyspeaking,theconstructionoftheShengTaiXianphoenixmountaininrecentyearshavemadetheremarkableeffect,comprehensivebenefitgrowthobvious,andtheeconomicbenefitisthemostobviouschanges;Ecologicalbenefitoverallinthesmoothdevelopment.Forthis,weneedtofurtherimprovetheecologicalenvironmentoftheFengShanXian,improvetheecologicalbenefit,makethesystemasawholebeincreased.ThroughtheFengShanXianecologicalbenefitevaluation,furtherclarifytheforatimeforecologicalconstructionofthemaintaskandwork,throughtheecologicalprojectimplementation,tofurthercoordinatetherelationshipbetweeneconomicIIdevelopmentandtheenvironment,FengShanXianwillformeconomicdevelopmentabeautifulenvironment,socialenvironmentharmoniousnewsituation.Keywords:ShengTaicountyconstructionbenefitevaluationpho...
