Abstract

Maintaining the standard of water quality in an aquatic habitat necessitates continual assessment of its physicochemical properties. The purpose of this study was to evaluate physicochemical properties and to discuss the causes of spatiotemporal variability in key physicochemical parameters at five different locations of Dal Lake. Water samples were collected in four seasons for 3 years (i.e., January 2019-December 2021) to evaluate various physicochemical properties using standard methods. The analysis shows that the macrophytic development has increased due to organic and inorganic load, leading to the Lake's deterioration. The analysis indicates positive and negative correlations among various parameters across five sampling sites. Principal component analysis shows that two components (PC1 and PC2) explain 47.35, 47.54, and 48.11% of the variability in the years 2019, 2020, and 2021, respectively. From 2019 to 2021, the continuous decrease in dissolved oxygen and increased levels of magnesium, conductivity, alkalinity, total hardness, calcium hardness, total phosphorus, and nitrate-nitrogen suggest a trend toward eutrophication in the lake.

了解达尔湖水动态:生理参数和季节变化的综合分析。
要保持水生栖息地的水质标准,就必须对其理化特性进行持续评估。本研究旨在评估达尔湖五个不同地点的理化特性,并讨论主要理化参数时空变化的原因。研究人员在 3 年内(即 2019 年 1 月至 2021 年 12 月)的 4 个季节采集水样,采用标准方法评估各种理化特性。分析结果表明,由于有机和无机负荷的影响,大型藻类增多,导致湖水恶化。分析表明,五个取样点的各种参数之间存在正相关和负相关关系。主成分分析表明,2019 年、2020 年和 2021 年,两个成分(PC1 和 PC2)分别解释了 47.35%、47.54% 和 48.11%的变异性。从 2019 年到 2021 年,溶解氧持续下降,镁、电导率、碱度、总硬度、钙硬度、总磷和硝酸盐氮水平上升,表明湖泊有富营养化的趋势。
