摘要

Water chemistry and plankton has been monitored in three Lakes in Tyresta National park SE of Stockholm since 1977. Liming operations started in Lake Langsjon and Lake Trehirningen in 1978 and were repeated every 3-5 years, while Lake Arsjon is an unlimed Reference Lade. During 1991-1999, the annual pH median in Lake Langjon and Lake Arsjon Ranged between 6.6-7.1 and 5.2-5.8, respectively, and the composition of phyto-and zooplankton In these lakes did not change markedly.
