| 摘 要： | 评价郑州市景观河流的富营养化现状可为科学防治景观水体富营养化提供科学依据。选取人民公园和紫荆山公园的景观湖为研究对象,供选定7个采样点,于2010年3～4月每周进行GPS定位采样。选取综合营养状态指数和修正的卡尔森营养状态指数法评价郑州市2座公园景观水体营养化情况。研究结果表明,人民公园和紫荆山公园取样点的水体TLI均值分别为66.80、64.74,TSIM为58.615,9.94。由此可知,2座公园景观水体富营养化程度均为中度富营养化,应及时控制与治理。对此,笔者提出利用植物净化水体,减少内源营养,控制外源营养的水体富营养化防治方法。

| Abstract: | 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,landscape water eutrophication of the two parks had been evaluated.The research results showed that the average values of TLI of sampling waters in the two parks were 66.80 and 64.74;those of TSIM were 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 nutrition,and control exogenous nutrition by using plants. |
