大连地区沿海小流域地下水库开发潜力分析

迟宝明,周彦章,易树平,李志军(,130026):大连地区受自然条件及多方面因素影响,水资源利用率较低,缺水问题严重为缓解区内缺水问题,本文试分析大连地区沿海小流域水资源特点及开发利用现状,通过对拟建地下水库可行性论证和开发潜力分析,说明修建地下水库通过地表-地下联合调蓄是解决大连沿海地区水资源紧缺问题的理想途径之一在区域水资源可持续开发的基础上,进一步为解决我国北方沿海小流域地区普遍的水资源紧张问题提供理论和实践依据:大连地区;沿海小流域;水资源;地下水库;开发潜力:P6418:AAbstract:Fortheeffectofnaturalconditionandmanyotherfactors,theutilizationofwaterresourcesisverylowandtheproblemoflackingwaterisseriousinDalianarea.Inordertoreleasetheproblemoflackingwater,thispaperanalyzesthecharacteristicsofwaterresourcesinDalianinshoresmallbasinarea,andthestatusoftheexploitationandutilizationatpresent.Bydemonstratingthepossibilityandanalyzingthepotentialofexploitationinbuildingthegroundwaterreservoir,itilluminatesthatthemethodsbuildinggroundwaterreservoirandsurfacewate-rgroundwaterjointregulationisoneoftheidealmethodstoreleasethewaterlackingprobleminDalianinshorearea.Basedontheregionalwaterresourcesustainabledevelopment,therearesometheoreticalandpracticalfoundationstoresolvetheproblemoflackingwaterinthenorthinshoresmallbasinareasofChina.Keywords:Dalianarea;inshoresmallbasin;waterresources;groundwaterreservoir;exploitivepotential:2005-10-13;:2006-01-18:.:(1957-),(),,,.,,,,,1/4,,201022108m3/a[1],,,,-,,,1,[2](),11大连沿海(滨海)小流域特点631,126104km2()200,km21000km2,,,,,,,----;--,,,,,,,,,100,232006年第5期工程勘察JournalofGeotechnicalInvestigation&Surveying,12水资源时空分布特征,,,28~38;6~9,75%,,8~15,6~981%~85%,,550mm/a950mm/a,150~500mm/a(1),1611108m3/a,744108m3/a,680108m3/a,408108m3/a1,,,;272108m3/a,231108m3/a,219108m3/a,154108m3/a13区域水资源利用现状2000,1435,261(613242)206248720,,,,35%,25%,,16%(1),34%,,,2440104m3/a,,61%(1),144%2002,4058km21(108m3)16116807444080393482(108m3)35223723006500038843(%)223531160825(108m3)272231154219008884(108m3)085040043133003304(%)31172861383424工程勘察JournalofGeotechnicalInvestigation&Surveying2006年第5期221地表水资源开发利用的相对局限性,,,,200(1),(97%50km)(13~141),,3,,,,,,,,,,22沿海小流域修建地下水库的可行性条件,,,,,[3],,,,-,,,3192108m3/a,(1481108m3/a),,[4],,,,,,,;,,,,,,,331沿海小流域修建地下水库的优势分析,,,,;,,,,50%,,90%[5],,,,,,,20%~50%,[6]32区域地下水库调蓄能力分析,,,[7](1)蓄水能力:V=MS,,:V,(m3);M(m2);252006年第5期工程勘察JournalofGeotechnicalInvestigation&Surveying(),022;S(m),1/2,22[8](2)2M(km2)(m)S(m)V(104m3)(104m3)61530~20057577797522251951~822547025253564515~10275390225302955902~1033894543288752~82548125469151203~83258580570662052~1542519167555331352~825192554864051~1027524502582652201~8225108952504251~7521251986875118351351~7259429022251~8225111375776717253~154517077557305453~827527225133901853~82281139639081484~839768595483953~1545391051392426091~1542295926510209610~8122754804870148508~571625303875231719408~1303451472465402111079863871114414776(2)调水能力,,,,,,,[7],,4,,,,,,,,,,[1].21[J].,2001,20(1):65~69.[2].[M].:,1991,1.[3],.[M].:,1995,80~82.[4],.[J].,2000,4:37~39.[5].[J].,2005,27(2):73~77.[6].-21[J].,2000,2:26~28.[7].[J].,2003,2:37~40.[8].[J].,2004,27(4):268~272.[9].[J].,2004,24:7~9.[10].[M].:,1987,48~49.(30)[2].[J].,1994,6(3):96~100.[3].[M].:,2003.9.[4],.[M].:,2001,9.[5]Taneja,D.S.,Khepar,S.D.Effectofartificialground-waterrechargeonaquiferparametersusingcavitywell[J].GroundWater,1996,34(2):335~340.[6]Abu-Taleb,MF.Useofinfiltrationfieldtestsforgroundwaterartificialrecharge[J].Environmental(Geology,1999,37(1-2):64-71.[7],,.[C]..:,2005,359-362.26工程勘察JournalofGeotechnicalInvestigation&Surveying2006年第5期
