摘要：

As an example for application of municipal sewage sludge as fertilizer for fruit trees in Xiamen City, transfer mechanism and statistics analysis were combined by experience and statistic models. The relation models of heavy metals were built between experimentation and control sample of grapefruit soil, such as As, Hg, Cu, Pb, Cr, Ni and so on. Transfer models of heavy metals also were built such as Ni from soil to leaves for control samples, Cu and Cr from soil to leaves for experimentation samples, As, Cu and Ni from soil to pulp for experimentation samples. The study afforded a research method for concentration forecast of heavy metals in the system of soil-plant for land application of municipal sewage sludge, and had been provided with practicality significance.
