DOI:10.16616/j.cnki.10-1326/TV.2023.08.02基于长系列水文数据的巢湖生态水位研究黄军(安徽省水利水电勘测设计研究总院有限公司,安徽合肥230088)【摘要】本文基于巢湖湖区1962—2017年长系列逐日水位资料,分析计算了巢湖历年特征水位及高低水位发生时间与历时;在此基础上分析确定了巢湖的生态水位,并对其生态水位保障程度进行了分析。主要结论有:ⓐ巢湖忠庙站最低生态水位为6.80m;ⓑ巢湖生态水位日、月、年保障程度均较高;ⓒ20世纪90年代中期以来,受湖区周边水资源开发利用影响,巢湖最低控制水位逐渐升高,虽有助于经济社会发展,但对湖区生态系统的可持续发展不利。建议积极开展巢湖生态水位调度研究,以保障巢湖生态系统健康。【关键词】巢湖;生态水位;时间与历时;保障程度中图分类号:P331文献标志码:B文章编号:2096-0131(2023)08-008-06ResearchonEcologicalWaterLevelofChaohuLakeBasedonLong-TermHydrologicalDataHUANGJun(AnhuiSurveyandDesignInstituteofWaterResourcesandHydropowerCo.,Ltd.,Hefei230088,China)收稿日期:2023-02-20网络首发地址:http://kns.cnki.net/kcms/detail/10.1326.tv.20230803.1127.004.html.基金项目:安徽省自然科学基金项目(2208085US14)作者简介:黄军(1989—),男,高级工程师,硕士,主要从事水文水资源、水资源规划等工作。Abstract:Basedonthedailywaterleveldatafrom1962to2017intheChaohuLakearea,thispaperanalyzesandcalculatestheannualcharacteristicwaterlevelsandtheoccurrencetiminganddurationofhighandlowwaterlevelsintheChaohuLake.Onthisbasis,theecologicalwaterleveloftheChaohuLakeisdetermined,andthedegreeofecologicalwaterlevelassuranceisanalyzed.Themainconclusionsareasfollows:(1)TheminimumecologicalwaterlevelattheZhongmiaoStationintheChaohuLakeis6.80m;(2)Thedaily,monthly,andyearlyassurancelevelsoftheecologicalwaterlevelintheChaohuLakearerelativelyhigh;(3)Sincethemid-1990s,duetothedemandsofwaterresourcesdevelopmentandutilizationinthesurroundingareasofthelake,theminimumcontrolwaterleveloftheChaohuLakehasgraduallyincreased.Althoughthishascontributedtoeconomicandsocialdevelopment,itisunfavorableforthesustainabledevelopmentofthelake’secosystem.ItisrecommendedtoactivelyconductresearchonecologicalwaterlevelregulationintheChaohuLa...
