摘　　要：The author summarized the advantages and potential risks of urban-rural organic wastes agricultural reutilization to reduce the potential risks of urban-rural organic wastes agricultural utilization. The results showed that： the organic wastes generated in urban-rural life as fertilizer applied into farmland made an impact on soil properties, then indirectly affected the soil microbial biomass and soil enzymes activities. In addition, the heavy metals in organic wastes would accumulate in the soil and damage to soil environment. Therefore, it was necessary to make a long- term research on the environment of soil which agricultural utilized of wastes.综述了城乡有机废弃物农用资源化的优点和潜在风险,旨在为城乡有机废弃物农业利用降低潜在风险。研究表明:城乡生活中产生的有机废弃物作为肥料施入农田后对土壤性质产生了影响,从而间接影响了土壤微生物量和土壤酶活性;有机废弃物中的重金属会在土壤中积累对土壤环境造成的危害,因此有必要对废弃物农用后的土壤环境进行长期研究。
