In this article,Canna,Cyperus and Penisetum were grown in artificial solution contained heavy metals such as lead and chromium to investigate their endurance to the two kinds of heavy metal.The experiment results showed that lead and chromium could decrease the height and biomass of plants even at low concentration of 2.0mg/L.

随着工业的迅速发展，各种工业废水和固体废弃物的渗出液直接排入水体，致使水体中重金属铅(Pb2+)和铬(Cr6+)等含量越来越高[1]，重金属不能像其他有机化合物那样可自然降解或生物降解，往往存在水体或沉积到水域底部或被水生植物浮游植物。

Thus, it is helpful to understand mutual reactions among pollutants in heavy metal polluted soil and eutrophic water, to clarify their biological and environmental effect through studying phototactic behavior of Daphnia influenced by nitrogen, phosphate and heavy metals.

因此，戮们筛选培育的隆线搔纯生物株是一种非常理想的生物监测器，优于国外培育使用的大型搔，可以根据隆线搔的趋光行为的变化来监测样品中的有害物质。②在水搔趋光指数测定过程中，测定装置的工作条件和参数显著影响结果。

The result showed that Imperata cylindrical, Digitaria sanguinalis, Erigeron acer Xanthium sibiricum and Hedyotis auricularia are the species with high tolerance to heavy metal pollutions adapted to the adverse conditions of wastelands. These species can be used as pioneer plants for recovety of the vegetation in the manganese-mined wastelands. The individual event pollution index of the heavy mentals, compared to their background values are higher than 2, with Pb as an exception, indicating that the soil in these areas has been contaminated and that Mn and Cd are the elements creating most serious pollution problems.

结果表明，白茅、马唐、飞蓬、苍耳、耳草对重金属有较强的耐性，而且能适应废弃地的不良环境，可作为锰矿废弃地生态恢复的先锋植物；用3种不同的背景值对废弃地土壤重金属污染程度的评价结果是一致的，除Pb外，5种重金属元素单项污染指数均大于2，表示被污染，其中以Mn、Zn、Cd污染最为严重。

In this subject we maked Hypnum hamulosum and Thuidium cymbifolium as objects to monitor the air pollution of heavy metal and SO2 of Nanjing city using moss bags,combined simulated test and monitoring of natural pollution to discuss the mechanism of mosses to be used as monitor of air pollution of heavy metals.

本课题以弯叶灰藓和大羽藓为研究对象，采用苔袋法对南京地区的大气重金属和SO2污染进行了监测，通过室内模拟培养与室外自然污染监测相结合的方法，对树木附生藓类监测大气重金属污染机理作了初步的探讨。

POD and SOD activities in Juncus Effuses increased first and then decreased afterwards, while CAT activity decreased linearly. In gerneral, the enzyme activities were gradually activated when the concentration of heavy metals was within the lower concentration range of the soil environmental quality which indicated their synergic resistance to heavy metal stress to a certain degree.

在接近土壤环境质量标准低浓度设计范围内，灯心草3种保护酶有逐渐被激活的趋势，表现出一定的协调性共同抵制重金属的毒害。

This paper analyses the different concentrations of Pb, Zn ion hybrid seedlings on the soil culture camphor several physiological indicators of the impact of the results show that the experimental results show that, POD, SOD, CAT, such as the biological oxidation resistance of the show is basically change the trend promoting high-low suppression trend, proline, MDA membranaceous permeability, as well as the content, with the concentration of heavy metals increases, reflecting the biofilm was heavy metal ions damage situation.

本文分析了不同浓度的Pb、Zn混合离子对土培香樟幼苗的几种生理指标的影响，结果表明，实验的结果表明，POD，SOD，CAT等抗氧化性的生物酶的改变趋势基本上呈现低促高抑的趋势，而脯氨酸，丙二醛以及膜质透性的含量是随着重金属浓度的增大而增大，体现出了生物膜被重金属离子的破坏的情况。
