洱海总磷总氮污染现状分析

:2006-01-17洱海总磷总氮污染现状分析(,671000):根据2004年洱海水质的实测数据,对洱海总磷总氮污染现状进行了分析评价:洱海全湖多数测点和断面的总磷总氮平均浓度都不超出类水质标准,但其水体中氮磷浓度已处于较高水平,洱海实际上正步入由中营养向富营养化转化的关键期;对洱海氮磷的来源作了简要分析,并针对实际情况提出污染防治措施:污染现状;总磷;总氮;防治措施;洱海:X820:A:1006-947X(2006)增刊-0113-0320041,4,3,121,05m05m,288,1,41212341-1232-4563-7894-101112(1)-30032mg/L0027mg/L0036mg/L,0032mg/L36,3333%,6111%,2,310,0139mg/L(2)-30028mg/L0025mg/L0027mg/L,0026mg/L36,5000%,4722%,1,46,0073mg/L(3)-30033mg/L0028mg/L0030mg/L,113云南环境科学2006,25(增刊):113-115CN53-1093/XISSN1006-947X0030mg/L36,2500%,7222%,1,73,0068mg/L(4)30032mg/L0039mg/L0031mg/L,0034mg/L36,2222%,6944%,3,119,0068mg/L,2;106(0066mg/L)(5)2004,005mg/L,0031mg/L,,11,,2,2,,412,11,,2,,-,2:5-123(1)30597mg/L0572mg/L0597mg/L,0589mg/L36,4167%,5556%,2,310,1464mg/L(2)-30566mg/L0515mg/L055lmg/L,0544mg/L36,4167%,5833%,65,0980mg/L6-4567-7898-101112(3)-3058lmg/L0554mg/L0549mg/L,056lmg/L36,3056%,6667%,1,95,1044mg/L(4)-30608mg/L0660mg/L0534mg/L,060lmg/L36,2778%,6944%,1,119,1098mg/L(5)2004,05~10mg/L,0574mg/L,,1114云南环境科学第25卷增刊2006年6月4~11,,,,2,,,3,,,,V,V18~V,V,18,,,200411939~14164,t108085~18023t2004500136,,,30,,4(1),,,,,,,,18,,18,,,;,,,,,;,,(2),,,,,,(3),,(4),,,,,(5),,,,,,,51996,,(),,,();,,,,,GB3838-2002III,(112)115洱海总磷总氮污染现状分析杨晓雪,,,,,,,(2),2003,,(3),,,(4),,,,(5),,:[1][A][C]:,1984[2][A][C]:,1989[3][M]:,1987StudyonTrendLawsofMicrobiologyinErhaiLakeYANGJie-chang(DaliStationofEnvironmentalMonitoring,DaliYunnan671000,China)Abstract:Basedontheroutinemonitoringdatafrom2004to2004ofmicrobiologyinErhailake,thechangelawsofmicrobiologyisstudied.Combiningwaterqualityassessmentindicatorsofmicrobiology,waterqualityandeutrophicationsituationofErhailakeareassessed.Keywords:waterqualityassessmen;tmicrobiology;trendlaw;Erhailake(115),(02mg/L,002mg/L),,,,,AnalysisonTotalPhosphorusandTotalNitrogenPollutioninErhaiLakeYANGXiao-xue(DaliStationofEnvironmentalMonitoring,DaliYunnan671000,China)Abstract:Thispaperpresentsacomprehensiveanalysisonthetotalphosphorus(TP)andtotalnitrogen(TN)conditioninErhailakebasedonrecentmonitoringdata.Asindicatedbythedatacollectedin2004,althoughtheaverageTPandTNconcentrationsatmostmonitoringstationsandcross-sectionsinthelakearelowerthanthetargetconcentrationsofGradewaterqualitystandard,therelativelyhighnutrientconcentrationsinthelakedoesevidencethatthelakeisexperiencingatransitionfromthemesotrophictoeutrophiccondition.ThepaperthenprovidesfurtheranalysisofthesourcesofTPandTN,andproposespollutioncontrolcountermeasuresbasedonthewaterqualityandsourceanalysis.Keywords:pollutionsituation;totalphosphorus;totalnitrogen;countermeasure;Erhailake112云南环境科学第25卷增刊2006年6月
