查干湖湿地富营养化变化趋势分析及其防治措施探讨

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。

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

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.
