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 objective of this study is aimed at the implementation of parallelized numerical quadrature routines. The algorithm we choose for numerical quadrature routines is the so called "Adaptive Romberg Tree integration scheme"(abbr."ARTint") proposed by Lin et. al.[1997]. This numerical quadrature scheme can arrange the function evaluation points adaptively in accordance with characteristic of the trend of variation in integrand function values. When the accuracy of the numerical quadrature value is requested to be increased, a newer and larger set of function evaluation points must be incurred. The main advantage of ARTint method is the inclusion of all function evaluation points used in previous stages. It is this feature of ARTint method that makes it a quadratue scheme with prominent computation efficiency.

本研究在探讨数值积分程式之平行化，所使用的演算法为林聪悟与林佳慧[1997]一书所提出的「Romberg树自动布点数值积分」架构，此一数值积分方法能以适应被积函数值变化情形方式自动安排积分点来进行数值求积计算，在提高阶数以获得更高精度积分值的过程中，此一方法只须再计算新增加积分点的函数值，搭配先前已计算过的函数值的重覆运用即可获得更精确的数值积分估计值，如此将能减少升阶过程中函数求值计算的次数，有效率地完成单重积分的数值计算。

其中，脆弱性评估和资源布局评估是应急预案评估中的两个重点问题，如果在应急预案制定过程中脆弱性评估不足，则难以找到地区脆弱性所在并加以特殊应对，最终导致因脆弱性较强而损失较大；而在处置过程中出现资源不足或者调度不力等情况则与资源布局关系密切，需要事先确定资源布局并评估其合理性。
