艾丁湖生态水位监测及湿地水域变化分析

Ecological Water Level Monitoring and Wetland Aquatic Area Change Analysis in Ayding Lake

为进一步认识艾丁湖流域吐鲁番盆地水生态环境现状及发展变化情况,本文以艾丁湖湿地植被生境区域为研究对象,采用地下水埋深定位监测井及湿地水域变化评估方法进行分析。结果表明,艾丁湖地下水埋深2021年为3.57~5.37m,2022年为4.48~6.36m,年内各月地下水埋深大小变化趋势基本相同;艾丁湖水域面积经历了减小—增加—再减小的过程,2016—2021年湿地生境趋好,水域面积增加,2022年流域遭遇罕见高温干旱,艾丁湖水域面积略有收缩。研究成果可为流域生态治理提供参考。

To further understand the current status and developmental changes of the water ecological environment in Turpan Basin of Ayding Lake Watershed,this paper focuses on the wetland vegetation habitat area of Ayding Lake.It employs methods involving the use of groundwater depth monitoring wells and wetland aquatic area change assessment.The results indicate that the groundwater depth in Ayding Lake ranged from 3.57 to 5.37 meters in 2021 and from 4.48 to 6.36 meters in 2022.The variations in groundwater depth for each month within the year were generally consistent.The water area of Ayding Lake experienced a process of reduction,expansion,and subsequent reduction.From 2016 to 2021,there was an overall improvement in the wetland habitat,with an increase in water area.However,in 2022,the watershed experienced an unusual period of high temperatures and drought,leading to a slight contraction in the water area of Ayding Lake.The research findings can serve as a reference for watershed ecological management.
