确定区域水资源分配权重的最小相对熵方法金菊良1,程吉林2,魏一鸣3,李如忠4(11合肥工业大学土木建筑工程学院,合肥230009;21扬州大学水利科学与工程学院,江苏扬州225009;31中国科学院科技政策与管理科学研究所,北京100080;41合肥工业大学资源与环境工程学院,合肥230009)摘要:区域水资源合理配置是实现区域可持续发展与水资源可持续利用的重要调控措施,其关键问题之一就是如何合理、简便地确定各子区域的水资源分配权重。为此,提出用信息论中的最小相对熵原理挖掘区域水资源配置过程中各子区域客观信息与各专家的经验信息,进而确定区域水资源分配权重的一套新方法(MRIEM)。结果表明:用MRIEM确定各子区域水资源分配权重,数学物理概念明确,方法简明、通用,计算结果客观、合理;MRIEM是一种从定性到定量综合集成的组合赋权方法,在系统工程理论与实践中具有一定的推广应用价值。关键词:水资源合理配置;权重分配;最小相对熵原理:层次分析法;遗传算法;综合集成方法论中图分类号:TV21214文献标识码:AMinimumrelativeinformationentropymethodfordeterminingweightsofregionwaterresourcesallocationJINJuliang1,CHENGJilin2,WEIYiming3,LIRuzhong4(11CollegeofCivilEngineering,HefeiUniversityofTechnology,Hefei230009;21CollegeofConservancyandHydraulicEngineering,YangzhouUniversity,Yangzhou,JiangsuProvince225009;31InstituteofPolicyManagement,ChineseAcademyofSciences,Beijing100080;41CollegeofNaturalResourcesandEnvironmentalEngineering,HefeiUniversityofTechnology,Hefei230009)Abstract:Reasonablewaterresourcesallocationisanimportantcontrolmeasureforregionsustainabledevelopmentandwaterresourcesutilization,whichkeyproblemishowtohandilydetermineweightsofregionwaterresourcesallocation.Forthispurpose,anewschemefordeterminingweightsofregionwaterresourcesallocation,namedMRIEMforshort,wasproposedtomineobjectiveinformationofsub2regionsandexperienceofexpertsduringthewaterresourcesallocationprocessbasedontheprincipleofminimumrelativeinformationentropy.Theresearchresultsshowthatasameta2synthesismethodfordeterminingweightsofregionwaterresourcesallocationwithdistinctconceptofmathematicsandphysics,MRIEMishandyanduniversal,itscomputationresultisobjectiveandreasonable,soitcanwidelybeappliedtotheoryandpracticeofdifferentsystemsengineering.Keywords:reasonablewaterresourcesallocation;weightdistribution;principleofminimumrelativeinformationentropy;analytichierarchyprocess;geneticalgorithm;meta2synthesismethodology0引言区域水资源合理配置是根据有效性、公平性和可持续性等原则以及市场经济规律与资源配置准则,通过合理抑制需求、保障有效供给、维护和改善生态环境质量等各种工程与非工程措施,对多种可利用水源在区域间进行收稿日期:2005206208基金项目:国家自然科学基金项目505
