英文摘要	Ecological restoration is an efficient method to reduce the degradation of natural coastal wetlands.Restoration age has important effects on soil chemical properties and plant community characteristics.However,long-term monitoring on the effects of wetland restoration projects and their underlying mechanism is still limited.Here,we examined the effects of different restoration ages (0,3,7,10,and 19 years) of wetlands on soil properties,plant species diversity,and community stability in the Yellow River Delta.The results showed that soil electric conductivity,available phosphorus concentration,and available potassium concentration decreased with increasing restoration age.However,soil available nitrogen concentration increased during the restoration process.Shannon index,Pielou evenness index,and species richness index of plant communities increased continuously with increasing restoration age,while plant diversity indices were mainly driven by the changes in soil electrical conductivity.In addition,restoration age also promoted plant community stability,which was significantly and negatively related to soil electric conductivity,available phosphorus and available potassium,and positively related to available nitrogen concentration.With the proceeding of restoration,soil environment and plant community structure improved continuously.Therefore,restoration projects can stimulate positive succession of community and improve the stability of coastal wetland ecosystems.
中文摘要	生态修复是遏制滨海湿地退化的重要手段。修复年限对湿地土壤化学性质、植物群落特征具有重要影响。然而,目前关于滨海湿地生态修复效果及其潜在机制的长期监测相对较少。本研究以黄河三角洲不同修复年限(0、3、7、10、19年)湿地为对象,探究修复年限对土壤化学性质、植物物种多样性以及群落稳定性的影响。结果表明:随修复年限的增加,土壤电导率、速效磷和速效钾含量呈减小趋势,土壤速效氮含量呈增加趋势;植物群落Shannon指数、Pielou均匀度指数、物种丰富度指数随修复年限的增加呈增大趋势,土壤电导率是影响植物物种多样性的主控因子;随修复年限的增加植物群落稳定性指数也呈增大趋势,植物群落稳定性指数与电导率、速效磷含量、速效钾含量呈显著负相关,与速效氮含量呈显著正相关。因此,随修复年限的增加,土壤环境与植物群落结构不断改善,修复工程能够促进植物群落的正向演替并提高滨海湿地生态系统的稳定性。
