abstract = {Environmental change in Lake Taihu and its catchment since
the early to middle part of the twentieth century has left a
clear geochemical record in the lake sediments. The human
activities in the lake and its catchment responsible for the
change include agriculture, fisher, urbanisay tion, sewage
and industrial waster disposal. Sediment cores were
collected from Meilian Bay of northern Lake Taihu to
investigate the record of anthropogenic impacts on the
lake's ecosystem and to assess its natural,
pre-eutrophication baseline state. Two marked stratigraphic
sediment units were identified on the basis of total
phosphorus concentration (TP), pigments, total organic
carbon (TOC)/total nitrogen (TN), delta C-13 and delta N-15
corresponding to stages in the lake history dominated by
phytoplankton, and by aquatic macrophytes. Results show that
as TP loading increased from the early 1950s the lake
produced sediments with increasing amounts of organic matter
derived from phytoplankton. In the early 1950s, the first
evidence for eutrophication at the Meilian Bay site is
recorded by an increase in C/N values and in sediment
accumulation rate, but there is little change in phosphorus
concentrations, pigments, delta C-13 and delta N-15 at this
time. After 1990 a more rapid increase in trophic status
took place indicated by increased levels of phosphorus,
pigments, delta N-15 and by decreased delta C-13 and TOC/TN
values in the lake sediments. The first increase in trophic
status of the early 1950s results mainly from agricultural
development in the catchment. In contrast, the acceleration
from ca. 1990 originates from the recent development of
fisheries and the urbanisation and industrialisation of the
catchment.},
