摘要

本文介绍了湖泊最高温度随时间变化的结果。分析是在位于波兰北部的9个湖泊的基础上进行的。该分析基于1971年至2015年期间的每日水温和气温。曼-肯德尔和森的试验被用于确定最高空气和水温的变化方向和速率。湖泊最高水温平均上升0.39°C(12月1日)，最高气温平均上升0.48°C(12月1日)。采用聚类分析(CA)对最高水温变化特征相似的湖泊进行分组。第一组包括5个湖泊，其中最高温度趋势值为0.41°C dec-1。第二聚类的最大水温上升幅度平均值小于第一聚类(0.36°C / 1)。聚类分析结果与形态计量学数据的比较表明，第一类湖泊的平均深度、最大深度和水体透明度均大于第二类湖泊。

The increasing of maximum lake water temperature in lowland lakes of central Europe: case study of the Polish Lakeland

The paper presents the results of time-related changes in maximum temperatures in lakes. The analysis was carried out on the basis of 9 lakes located in the northern part of Poland. The analysis was based on daily water and air temperatures in the period 1971–2015. Mann–Kendall's and Sen's tests were applied to determine the directions and rates of change of maximum air and water temperatures. The average increase of maximum water temperature in analysed lakes was found to be 0.39 °C dec–1, while the warming trend of the maximum air temperature was 0.48 °C dec–1. Cluster analysis (CA) was used to group lakes characterised by similar changes of maximum water temperature. The first group included five lakes in which the values of the maximum temperature trends were 0.41 °C dec–1. In the second cluster the average value of maximum water temperature increase was smaller than in the first cluster (0.36 °C dec–1). Comparing the results of cluster analysis with morphometric data show that in the first cluster lakes are having a greater average depth, maximum depth and water transparency in comparison to the lakes of the second cluster.

期刊介绍： Annales de Limnologie - International Journal of Limnology publishes papers on the ecology of freshwater systems, ranging from studies of aquatic organisms, physical and chemical works which relate to the biological environment, to ecological applications and frameworks for water management directives. Main topics: Ecology of freshwater systems ; biodiversity, taxonomy, distribution patterns in space and time, biology of animals and plants ; experimental and conceptual studies which integrate laboratory and/or field work on physiology, population dynamics, biogeochemistry and nutrient dynamics, management, mathematical modelling ; techniques for sampling and chemical analyses, ecological applications, procedures which provide frameworks for environmental legislation.
