Based on the evaluation system, the plants whose relative remediation age was between 0~10 years were named as"Hyperaccumulator"and those between 10 ~ 50 years were named as"Accumulator".7 In the experiments six kinds of substrates were mixed with different solid wastes and the absorption and enrichment of plants on heavy metal Cd was studied. The results showed that relative remediation age was an ideal index to evaluate the capability of the phytoremediation on heavy metals, because it took into account more factors which affected the absorption evaluation effects than others, such as the heavy metal content and the biomass of the over-ground part of plants, the heavy metal content and the whole gross in substrates, harvesting frequency of plants and the environment standard of heavy metal. This made relative remediation age be suitable to the sorption capability evaluation of not only different plants on one heavy metal but also one plant on different heavy metals.8 It can be drawn from the relative remediation age of heavy metal Cd that the absorption capability of different plants was not same.
以相对修复年限为评价指标定义相对修复年限为0-10年的植物为"超富集植物",10-50年的植物为"富集植物"。7在由不同废弃物按一定的比例混合配制的六种土地复垦基质上,系统地研究了几种植物对重金属镉的吸收和富集情况,结果表明,相对修复年限既适用于不同植物对同一种重金属元素的吸收能力的评价,又适用于同一植物对不同重金属元素的吸收能力的评价,是衡量重金属元素植物修复效果的理想指标。8从不同植物对同一基质重金属镉的吸收和富集能力看,不论是经过多年种植的基质,还是第一次种植的基质,小白菜和油菜都是相对理想的植物;而黑麦草、高羊茅和苜蓿的吸收效果并不理想。

The results showed that:Under NaCl stress,the reductions in the shoot and root dry weight, leaf area,stem diameter of grafted plant were lower than those of ungrafted plants.The Na~+ content,Na~+/K~+ ratio,Na~+/Ca~(2+) ratio in the leaf and scion stem of grafted plants were lower whereas those of in the rootstock stem ad root were higher than in ungrafted plants. The K~+ contents,soluble sugar contents,shoot water contents,SOD,POD,CAT,APX activity,the stability of AsA/DHA,Photosynthetic rate,transpiration rate and stomatal conductance were higher,whereas the MDA contents in the leaf of grafted plants were lower than that in ungrafted plants.The reductions in leaf area and stem diameter of grafted \'Jinchun No.2\' plants were more severe than those of grafted \'Zaoduojia\' ones.
结果表明,盐胁迫下,嫁接苗地上部和根干重、叶面积、茎粗降低的程度显著低于自根苗;嫁接苗叶片和接穗茎中Na~+含量和Na~+/K~+、Na~+/Ca~(2+)比值显著低于自根苗,而砧木茎和根中的Na~+含量和Na~+/K~+、Na~+/Ca~(2+)比值显著高于自根苗;嫁接苗叶片中K~+含量、可溶性糖含量、地上部含水量、SOD、POD、CAT、APX活性、AsA/DHA的稳定性、光合速率、蒸腾速率、气孔导度显著高于自根苗,MDA含量显著低于自根苗。

The results showed that:The reductions in the shoot and root dry weights, leaf area,stern diameter of grafted plants were lower than those of ungrafted plants under the same NaCl stress.Na~+,MDA,H_2O_2 contents,O_2~- producing rate,Na~+/K~+ ratio, Na~+/Ca~(2+) ratio were lower,whereas K~+,solube sugar,shoot water content,SOD,POD, CAT,APX activity,the stability of AsA/DHA,Photosynthetic rate,transpiration rate and stomatal conductance in the leaf of grafted plants were higher than those of ungrafted plants at the same NaCl stress.Intercellular CO_2 concentration of grafted plants decreased whereas that of ungrafted plants increased significantly under salt stress.
结果表明,盐胁迫下,嫁接苗地上部和根干重、叶面积、茎粗受抑制的程度显著低于自根苗;嫁接苗叶片中Na~+、MDA、H_2O_2含量、超氧阴离子产生速率、Na~+/K~+和Na~+/Ca~(2+)比值显著低于自根苗,而叶片中K~+含量、可溶性糖含量、地上部含水量、SOD、POD、CAT、APX活性、AsA/DHA的稳定性、光合速率、蒸腾速率、气孔导度显著高于自根苗;嫁接苗的胞间CO_2浓度显著下降,自根苗的则显著上升。

The others are Mucuna sempervirens,Parthenocissus trcuspidata,Wistaria sinensis Sweet in turn.According to the distinction of ecological functional of these four plants,the kind of plants which should be chosen under various ecological environment conditions or for different demands of ecological function of the plants were given.1. The most suitable plants for the area which get serious pollution such as factory,roadway and so on is Mucuna sempervirens.the other plant which more suitable is Rosa banksiae Ait.2. The most suitable plants for the hospital and the area for the children and the old is Mucuna sempervirens. And we can also select Parthenocissus trcuspidata.3. In the green area of modern enterprise that produce precision instrument,Rosa banksiae Ait is the best selection.4. Rosa banksiae Ait is the most suitable plants in resident green area. Planting Mixed with Mucuna sempervirens has better effectiveness.
以四种植物的生态功能性差异评价为依据,提出不同生态环境条件下和对植物不同的生态功能性要求的垂直绿化应选择的植物: 1 在道路、工厂等污染较严重的地区搞垂直绿化,最合适的植物是油麻藤,其次可选择木香; 2 医院及儿童、老人活动区的垂直绿化首选是油麻藤,其次是爬山虎; 3 生产精密仪器的现代企业绿地,垂直绿化植物选择以木香为首选,可结合大面积的爬山虎墙面绿化; 4 居住区绿地的垂直绿化植物选择以木香最符合要求,再以油麻藤进行混植,效果较好。

In order to remove different concentrations of suspended sediment, a serial connected system of emerging plants, floatingleaved plants and submerged plants based on spatial distribution of natural water body was constructed by aquatic marcrophytes, such as Cyperus alternifolius, Acorus tatarinowii, Trapa japonica, Ceratophyllum demersum, Hydrilla verticillata and Vallisneria spiralis. Sandy water then flew through emerging plants, floatingleaved plants and submerged plants.
