The evaluation of landscape water eutrophication in Zhengzhou City could provide a scientific basis for the prevention of eutrophication.By taking landscape lakes in People Park and Zijing Mountain Park as the research objects,and selecting seven sampling spots,GPS had been conducted every week from March to April of 2010.By making use of TLI and TSIM,the landscape water eutrophication of the two parks had been evaluated.The research results showed that the average value of TLI of sampling waters in the two parks was 66.80 and 64.74;those of TSIM was 58.61 and 59.94,respectively.It could be known that landscape water eutrophication of the two parks was moderate and should be controlled and treated in time.Finally,the paper had pointed out that it should purify waters,reduce endogenous nutritions,and control exogenous nutritions by cultivating plants.
