Close-to-nature forest management is a sustainable approach aimed at achieving balance between ecological and economic benefits. The cultivation of future crop trees in the later successional stages following removal competitive crucial for promoting positive development trajectories succession. Understanding dynamic process growth investment strategies facilitates rational planning cycles scopes, ultimately enhancing quality tree cultivation. This study was conducted Pinus massoniana secondary with close-to-nature Ningbo City, Zhejiang Province, using handheld mobile laser scanning technology to precisely reconstruct structure trees. Over period 2–5 years initial implementation management, 3D point cloud data were collected annually from both managed reference (non-managed) plots. Using these multi-temporal data, we analyzed dynamics strategies, structural components, crown competition A linear mixed-effect model applied compare temporal variations indices control Our results revealed that height-to-diameter ratio gradually declined over time, while crown-to-diameter initially increased then decreased These trends significantly different those observed Additionally, height rates plots consistently lower than plots, whereas diameter breast (DBH) higher. Furthermore, gap area their neighboring diminished, overlap progressively increased. suggest growth, driven by competition, shifted toward DBH management. In stage after trees, benefited ample radial space minimal competition. However, as became increasingly limited, enhance mechanical stability achieve balanced structure. processes underlying mechanisms contributes predicting community development, improving productivity, maintaining diversity, ensuring
