Abstract

Jhanpa Baor, Aquatic macrophytes, Limnology, Physico-chemical parameters. Jhanpa Baor is a famous fresh water oxbow lake situated in Jessore district, Bangladesh. The physico-chemical parameters were analyzed from March 2021 to August 2021. Quadrates were ordered randomly and lengthening from boundary towards the lake center. The aquatic macrophytes found in each study site were listed species wise and the information was documented. A total number of 12 aquatic macrophytes were recorded from this area. The macrophytes were categorized into five morphological clusters as floating, submerged, free floating, floating creeper and emergent. The coverage of macrophytes near the periphery was higher than the central region of the lake. A number of physico-chemical analyses were conducted on the collected water samples, viz. pH (7.096 ± 0.06), electric conductivity (0.32 ± 0.01 mS/cm), temperature (32.14 ± 0.28 oC), dissolved oxygen (0.692 ± 0.12 mg/L), salinity (156 ± 8.94 ppm), water depth (10.91 ± 2.58 m), transparency (31.64 ± 3.52 cm) and phosphate (171.6 ± 4.56 μg/L).

孟加拉国杰索尔地区Jhanpa Baor水生大型植物多样性和水质评价

Jhanpa Baor，水生植物，湖沼学，理化参数。Jhanpa Baor是一个著名的淡水牛牛湖，位于孟加拉国杰索尔地区。分析了2021年3月至2021年8月的理化参数。四边形随机排列，从边界向湖中心延伸。在每个研究地点发现的水生植物按物种分类，并记录了相关信息。本地区共记录到水生植物12种。将其分为漂浮型、沉水型、自由漂浮型、漂浮攀缘型和涌现型5个形态类群。湖泊外围地区的植被覆盖度高于中部地区。对采集的水样进行了理化分析，包括pH值(7.096±0.06)、电导率(0.32±0.01 mS/cm)、温度(32.14±0.28 oC)、溶解氧(0.692±0.12 mg/L)、盐度(156±8.94 ppm)、水深(10.91±2.58 m)、透明度(31.64±3.52 cm)和磷酸盐(171.6±4.56 μg/L)。
