INFORMATION ABOUT BIOTOPE
关于生物栖息地的信息

Description of the area surrounding the biotope: The river in Lublin Voivodeship, which is the left tributary of the Bystrzyca river. It flows between the villages Zagórze and Krężnica. Then take a turn and heads east to the city of Bełżyce, in the village of Babin begins to meander strongly and help to create picturesque landscapes. The river is over 20km long and ends its course near Lublin, affecting the marshy area to the Bystrzyca river. Presented flooded area are the result of the beavers’ activities, they are surrounded by meadows, reed beds and fallen trees.
生物群落周边区域描述：这是卢布林省的河流，是比斯特里察河的左岸支流。它流经扎戈热和克雷什尼察两个村庄之间。然后转向东流，到达贝尔热茨市。在巴宾村开始变得蜿蜒曲折，帮助形成风景如画的景观。河流全长超过 20 公里，在卢布林附近结束其流程，影响比斯特里察河的沼泽地区。所展示的洪水区域是河狸活动的结果，它们被草地、芦苇丛和倒下的树木所环绕。

Description of the underwater landscape of the biotope: The bottom is covered with mud, and a small amount of plants and dead wood, creating excellent great environment for breeding fish. The only species I’ve seen is Gasterosteus aculeatus and Pseudorasbora parva, it is an invasive species and comes from Asia. For several years, permanently settled in Polish waters. The depth is small, about 20-50 cm, and the water temperature in the summer reaches even 28°C.
生物群落水下景观描述：河床覆盖着泥沙，有一些植物和枯木，为鱼类繁殖创造了极佳的环境。我只看到了两种物种：刺鱼（Gasterosteus aculeatus）和鲦鱼（Pseudorasbora parva），这是一种外来物种，来自亚洲。多年来，它已永久定居在波兰水域。水深较浅，约 20-50 厘米，夏季水温甚至可达 28°C。

Description of the parameters of the habitat: Turbid water, hardness about 20dH, pH is 7.5. Temperature in summer is 23-28°C, in winter the place completely freezes.

自然生物群落中发现的植物清单：箭叶蔓绿绒、沉水蓼、加拿大水盾草、直立柳、沼生聚细胞藻。

Threats to the ecology: The river was severely polluted in the 1980s and 1990s, leading to the complete extinction of Astacus astacus and Pseudanodonta complanata. Unfortunately, all the time Krezniczanka is exposed to the negative impact caused by humans, littering or flushed fertilizers from nearby fields negatively affect this small ecosystem.
生态威胁：河流在 20 世纪 80 年代和 90 年代严重污染，导致河虾和扇贝完全灭绝。不幸的是，长期以来克雷尼奇卡河一直受到人类活动造成的负面影响，乱扔垃圾或附近农田冲刷的肥料对这一小型生态系统产生负面影响。
