查干湖湿地富营养化变化趋势分析及其防治措施探讨

Discussion on the analysis of Chagan Lake wetland eutrophication trend and prevention measures

湿地被称为地球之"肾",在生态系统中具有重要不可替代的作用。总氮及总磷含量过高是导致水库、湖泊发生富营养化的主要因素,因此预防氮磷含量增高是减少湖泊富营养化发生的有效途径。作者通过对查干湖湿地近十年水质监测资料统计分析,找出氮磷含量的变化趋势以及湖泊富营养化变化趋势,针对氮磷含量过高原因,提出切实可行治理措施和建议,为有关政府决策部门提供了科学可靠依据。

High content of total nitrogen and total phosphorus is major factors that lead to eutrophication of reservoirs and lakes;Therefore the prevention against increasing nitrogen and phosphorus content is an effective way to reduce lake eutrophication.This article introduces a analysis of the statistic through nearly a decade of water quality monitoring data on Chagan Lake wetlands,and identifies the trend of the nitrogen and phosphorus content and lake eutrophication;It provides the practicable control measures and recommendations for the relevant government decision-making departments.
