基于水生植物组合的富营养化水体变化趋势的统计分析

Statistical Analysis of Change Trend of Eutrophication Water Basing on Combination of Aquatic Plants

本文通过四种组合的水生植物吸收富营养化水体氮磷浓度的变化值,用SPSS软件进行了统计分析,分析并发现了四个组合中的苦草+浮萍组合与菖蒲+浮萍组合对溶解氧的显著差异性,结合溶解氧浓度变化趋势图,得出了苦草+浮萍组合是富营养化水体中吸收氮磷成分的最佳组合结论。

This paper introduces that, the significant difference in dissolved oxygen in the combinations of vallisneria ＋ duckweed,duckweed ＋ iris was gained, by using SPSS software to analyze variances of PH indictors of nitrogen and phosphorus in eutrophicated water of the four combinations of aquatic plant＇s absorption, and the conclusion that the combinations of vallisneria ＋ duckweed is the best was also obtained according to the variance trend of dissolved oxygen.
