Risk assessment and safe utilization zoning of heavy metals in Cultivated Land soil in Ledu District， Haidong City

Abstract： Implementing zoning and classification management of cultivated land is the key to rational and efficient utilization of land resources and protection of cultivated land. Based on the current soil environmental quality assessment standards， a soil heavy metal pollution assessment is conducted on cultivated land in Ledu district， Haidong city， and a safety utilization level classification scheme and management strategy are proposed. The results indicate that the cultivated land in the study area is at a low-risk or below level， with no areas of medium to high risk.
