| Zusammenfassung |
| Environmental/ecological models are widely used for lake management as they
provide a means to understand physical, chemical, and biological processes
in highly complex ecosystems. Most research has focused on the development
of environmental (water quality) and ecological models, separately. Limited
studies were developed to couple the two models, and in these limited
coupled models, a lake was regarded as a whole for analysis (i.e. considering
the lake to be one well-mixed box), which is appropriate for
small-scale lakes but is not sufficient to capture spatial variations within
middle-scale or large-scale lakes. In response to this problem, this paper
seeks to establish a zoning-based environmental–ecological coupled model for
a lake. Hierarchical cluster analysis was adopted to determine the number of
zones in a given lake based on hydrological, water quality, and ecological
data analysis. The MIKE 21 model was used to construct 2-D
hydrodynamics and water quality simulations. STELLA software was used to
create a lake ecological model that can simulate the spatial variations of
ecological condition based on flow field distribution results generated by
MIKE 21. Baiyangdian Lake, the largest freshwater lake in northern China, was
adopted as the study case. The results showed that the new model is
promising for predicting spatial variations of ecological conditions in
response to changes in lake water quantity and quality, and could be useful
for lake management. |
