Abstract

Abstract The reclamation of coastal wetlands for agriculture has expanded considerably over the last 40 years in China. Wetland reclamation could substantially alter soil properties, but so far, a systematic analysis of the changes in soil chemical elements after reclamation is missing on a national scale. In this study, we synthesized 418 pairs of data from 41 experimental studies and investigated the responses of soil organic carbon (SOC), total nitrogen (TN), and total phosphorus (TP) contents to coastal wetlands reclamation in China. The results showed that SOC significantly decreased by 24.77% after reclamation, while TN and TP were significantly increased by 23.57% and 13.55%, respectively. The changes…
