INFORMATION ABOUT BIOTOPE
关于生物群落的信息

Description of the area surrounding the biotope: The Glukharka River flows on the northwestern outskirts of St. Petersburg from Planernaya Street to the Lakhtinsky Spill. Previously, it flowed out of the swamps west of Lake Dolgoye. When the intensive development of the surrounding area began, the upper reaches of the river were drained and turned into elongated ponds. In the lower reaches, the river flows through the Yuntolovskaya forest park and flows into the northeastern part of the Lakhtinsky Razliv. The name of the river was given in the XVIII century. The area along which the river flowed at that time was swampy. The river has a mixed feed with a predominance of snow. In addition to meltwater, there are rainwater and groundwater. In the annual course of the water level, spring flood, summer low water, autumn high water and winter low water stand out. The modern river bed is straight 50–60 m wide and up to 2.5 m deep in the central part and 4.7 m in the estuary. The upper part of the bay is overgrown with aquatic vegetation, and in the middle and lower parts only along the water edge. Amplitude of water level fluctuation is up to 1.5 m. The bottom is sandy, sometimes rocky. The thickness of mud deposits is 10-15 cm.
生物群落周边区域描述：格卢哈尔卡河发源于圣彼得堡西北郊的普拉涅尔纳亚街，流经拉赫金斯基溢洪道。此前，该河源自多尔戈耶湖以西的沼泽地带。随着周边地区大规模开发的启动，河流上游被排干并改造为狭长的池塘。下游段则穿越云托洛夫森林公园，最终注入拉赫金斯基 разли夫 的东北部。这条河的名称始于十八世纪，当时河流流经的区域多为沼泽。该河补给类型属混合式，以雪水为主，此外还包括雨水和地下水。在年水位变化过程中，春季洪水、夏季枯水、秋季高水位和冬季枯水特征显著。现代河道笔直，宽度为 50–60 米，中央部分水深可达 2.5 米，河口处水深达 4.7 米。海湾上部生长着茂密的水生植被，而中下部仅沿水边分布。水位波动幅度可达 1.5 米。河底多为沙质，局部可见岩石。淤泥沉积层的厚度为 10-15 厘米。

Description of the underwater landscape of the biotope: The substrate consists of fine brown sand, larger rocks are grayish. There are many snags and leaves in the water, as the trees hang down along the shore above the river.
生物群落水下景观描述：底质由细棕沙组成，较大的岩石呈灰白色。水中遍布沉木和落叶，因为树木沿河岸垂悬于河面之上。

Description of the parameters of the habitat: The water is clear, has a tan color. Water parameters: 7.6 pH, carbonate hardness 4, total hardness 3. Water temperature on average about 10 ° C, depends on the time of year. The wind influences the flow in the river, in its absence the flow practically stops.
栖息地参数描述：水质清澈，呈茶色。水质参数：pH 值 7.6，碳酸盐硬度 4，总硬度 3。平均水温约 10°C，随季节变化而波动。风力影响河流流速；无风时，水流几乎停滞。

List of fishes and invertebrates occurring in the nature biotope: Carassius gibelio, Gobio gobio, Rutilus rutilus, Perca fluviatilis, Abramis brama, Perccottus glenii.
自然生物群落中出现的鱼类和无脊椎动物名录：银鲫（Carassius gibelio）、戈比奥鮈（Gobio gobio）、欧鲌（Rutilus rutilus）、河鲈（Perca fluviatilis）、欧鳊（Abramis brama）、葛氏鲈塘鳢（Perccottus glenii）。

List of plants found in the nature biotope: Carex stricta, Plantago media, Euphorbia palustris, Senecio paludosus.
自然生境中发现的植物名录：Carex stricta、Plantago media、Euphorbia palustris、Senecio paludosus。

Threats to the ecology: Due to intensive economic development, one of the most important unsolved environmental problems is the elimination of unauthorized garbage piles.
生态面临的威胁：由于密集的经济开发，消除非法垃圾堆成为最重要且尚未解决的环境问题之一。
