社会经济的迅速发展,对重金属资源的需求与日俱增,这些重金属资源在使用过程中不可避免地以多种途径进入环境。由于重金属本身难分解的特性,滞留在土壤中的重金属超过一定限量便会造成污染,破坏生态环境结构和稳态。基于此,探究不同农业种植模式下土壤中重金属镉、铅的含量变化情况。 With the rapid socio-economic development and the increasing demand for heavy metal resources, these heavy metal resources inevitably enter the environment in various ways during their use. Due to the heavy metal itself is difficult to decompose the characteristics of heavy metals remaining in the soil over a certain limit will cause pollution, damage to the ecological structure and steady state. Based on this, we explored the changes of heavy metal contents of cadmium and lead in soils under different agricultural planting patterns.
