Abstract Poplar ( Populus simoni ) plantations are crucial in the sandy regions of western Liaoning, serving key roles wind protection, sand stabilization, soil moisture regulation, and carbon sequestration. However, challenges such as suboptimal stand quality limited ecological benefits persist. This study aims to elucidate growth dynamics poplar their impact on content this region. We established 75 standard plots across various age groups densities Fuxin City, measuring diameter at breast height (DBH), tree (TH), content, content. found that DBH TH increase with increasing density young middle-aged forests, but opposite is true near-maturity, maturity, over-maturity, where decrease density. Soil rises younger while increases age, surface layers exhibiting higher concentrations. The stock these approximately 3.0 × 10 6 tons, highest recorded City. research provides a foundation for effective management development wind-prone, areas. Overall, optimizing managing forest distribution essential enhancing sequestration
