Title: Analysis on current status of soil environmental quality around the Shiyan Reservoir in Shenzhen City
Abstract: To evaluate the soil fertility and soil environment quality,the contents of several nutrients and heavy metals in topsoil(0~20 cm) around the reservoir were analyzed.The results showed that the soils around the reservoir were generally moderate and the content of phosphorus was the highst than the contents of other nutrients while the variability of phosphorus content was alsost the highest.Among the heavy metals,Pb content was the highest,followed by Zn,Cr,Cu,As and Cd,Hg content was the lowest one.But the ratios of Cd content of the soil exceed 50% compared with the value of local soil backgrounds.As estimated by Nenerow aggregate pollution index,the Cd pollution of the soil was lightly and the Hg pollution was latent while the other heavy metals had no pollution to the soil.Among the 12 soil samples,most of the samples were clean except that one sample was slightly polluted.Therefore,the soil environment quality around the Shiyan Reservoir was all right in general.
