Studies on biodiversities in eutrophication process of landscaping water body in Northern China
景观水体富营养化模拟过程中藻类演替及多样性指数研究

Tank microcosm has been used to simulate the eutrophication process of static water body in Northern China in landscaping function. The phytoplankton changes with the development of various dominant species. It was found that the dominant species were Xanthophyta in the last stage. Nine biodiversity indices calculated on the basis of phytoplankton data were studied for their usefulness for eutrophication studies in landscaping water body. As follows: Margalef's ,PIE ,Menhinick's ,Shannon-Wiener, Simpson's, McNaughton's dominance index, Species, OD ,Monk , as a tool for eutrophication assessment in Landscape water body environment , Monk index and Menhinick's index were the best suitable for token the contamination development, others not.
