Abstract

Plankton communities are very important for the functioning of aquatic ecosystems [1, 2]. Phytoplankton is the dominant primary producer in the aquatic environment, from which most food webs begin, and which produces oxygen necessary for aquatic organisms [3]. Indicators of phytoplankton development are used to assess the ecological state of water bodies [4]. By quickly responding to changes in the aquatic environment, phytoplankton can serve as an indicator of the state of the entire ecosystem. Objective—A comparative analysis of the state of phytoplankton in two lakes experiencing anthropogenic pressure and located on the island territory of the Solovetsky archipelago and on the mainland of the Arkhangelsk oblast in the Northern Dvina River basin. Lake Bannoe (Gagarye) is located on the territory of Solovetsky village. Previously, a leather processing plant and a bathing facility of the monastery were located on its shore. Now there are buildings of the Solovetsky branch of the Arkhangelsk experimental algae plant. Lake Kholmovskoye is located in the Primorsky district of the Arkhangelsk oblast, 18 km from the city of Arkhangelsk. On the western shore of the lake is the village of Kholm and summer cottages. From the side of Lake Kholmovskoye, the village of Kholm is surrounded by an artificially dug ditch, into which all household drains flow. On the northern shore are former household premises. An operating cage trout farm is located in the water area of the lake, which is a source of additional organic matter entering the lake waters.

根据夏季发育指标，俄罗斯欧洲部分北部岛屿和物质湖泊中的浮游植物

摘要

浮游生物群落对于水生生态系统的功能非常重要[1, 2]。浮游植物是水生环境中主要的初级生产者，大多数食物网都是从浮游植物开始的，并产生水生生物所需的氧气[3]。浮游植物发育指标用于评估水体的生态状况[4]。通过快速响应水生环境的变化，浮游植物可以作为整个生态系统状态的指标。目的——比较分析北德维纳河流域索洛维茨基群岛岛境内和阿尔汉格尔斯克州大陆两个遭受人为压力的湖泊中浮游植物的状况。班诺湖（Gagarye）位于索洛维茨基村境内。此前，修道院的岸边设有皮革加工厂和沐浴设施。现在有阿尔汉格尔斯克实验藻类工厂索洛维茨基分厂的建筑物。霍尔莫夫斯科耶湖位于阿尔汉格尔斯克州滨海边疆区，距离阿尔汉格尔斯克市18公里。湖的西岸是 Kholm 村和避暑别墅。霍尔姆村位于霍尔莫夫斯科耶湖畔，周围环绕着一条人工挖的沟渠，所有家庭排水沟均流入该沟渠。北岸是以前的住宅。湖水域内有一个正在运营的网箱鳟鱼养殖场，这是进入湖水的额外有机物的来源。
