摘　　要：以南通市码头改造工程为例,分析项目建设过程中的地表扰动变化、土壤流失情况、措施落实情况、生态效益评价。结果表明,在工程施工期,地表受到扰动破坏,土壤流失量急剧增加,至水土保持运行期,随着植被、地表状况的逐渐恢复,土壤侵蚀量趋于稳定减少。项目区并未引起水土流失灾害,水土保持措施运行相对完好,对该区域的水土流失起到了较好的防治作用。Taking the Nantong Port Renovation Project as an example,the changes in surface disturbance,soil erosion,implementation of measures,and ecological benefit evaluation during the project construction process are analyzed.The results show that during the construction period,the surface is disturbed and damaged,and the amount of soil erosion increases sharply.By the operation period of water and soil conservation,as vegetation and surface conditions gradually recover,the amount of soil erosion tends to decrease steadily.The project area did not cause any soil erosion disasters,and the water and soil conservation measures were relatively well implemented,playing a good role in preventing and controlling soil erosion in the area.
