Results show that the greenbelt is a man-made phytocommunity, with pinu massoniana and eucalyptus being the dominant species and the coverage rate over 85%.
The community has an outstanding dominant species and the arborous layer possesses a comparatively high diversity index.The similarity is rather striking among different quadrats species.
Halosere A plant community in a succession that starts on land periodically inundated by the sea. Haloseres include salt-and flooding-tolerant pioneer communities on mudflats and saltmarshes.
Hippophae rhamnoides L.subsp.sinensis is a heliophyte tree,so that some scholars consider it as a pioneer population,but others regard that the tree regenerate well in natural conditions.
The community species mainly consisted of Coleopteran and Lepidoptera secondly.The above-mentioned 2 species made up the main body of this community in which initial pests dominated in number.
The change trend was influenced by several reasons such as the aquatic habitat, the ecological characteristics of fish, the community structure of digenetic trematodes and import of live fish.
The ecological features of phytoplankton community were preliminarily studied in the Taihu Lake.The trophic level and saprobic degree of the lake were evaluated in whole and in sub areas respectively.
