Abstract:: The study on heavy metal contamination and potential ecological risk assessment of the superficial sediments was carried out in the section of Jiangan River located in the typical urban and rural ectone of Chengdu. The sediment samples were taken from 4 sites of Jiangan River including Hejiawan, Majiashi, Jinhuaqiao and Lianggangdaqiao. The concentrations of Cu, Pb, Cr, Ni, Mn, Zn and Cd in the sediment samples were measured, the heavy metal contamination of the river was analyzed by geo-accumulation index, and the potential ecological risk of Jiangan River was assessed by Hakanson index. The results showed that Hejiawan was polluted by Zn in middle degree, Majiashi, Jinhuaqiao and Lianggangdaqiao were polluted by Zn in slight degree, Hejiawan, Jinhuaqiao, and Lianggangdaqiao were polluted by Cu and Cr in slight degree. Jiangan River was in slight potential ecological risk. The 4 sites in the descending order of their potential ecological risk indexes was Hejiawan, Lianggangdaqiao, Jinhuaqiao and Majiashi. This order was related to the process of urbanization and the industry-agriculture distribution along the river. The environmental protection and management of urban and rural ectone should be strengthened during the process of urbanization.
