摘要：【Objective】This study aims to investigate the response of main growth parameters (mean tree height, mean DBH, and stand volume) of Robinia pseudoacacia plantations on the Loess Plateau of China to forest age, stand density and site index (SI), and to establish multi-factor coupling growth models for providing scientific basis of sustainable management of R. pseudoacacia plantations in this study region.【Method】Based on the data of sample plots collected from the field surveys in 2021—2022 and literature, the response relations and corresponding function types of mean tree height and mean DBH to the single-factors of forest age, stand density and site index were determined using the upper envelope line method. Then, a framework of multi-factor coupling growth models was established by a continuous multiplication of these function types, and the multi-factor coupling growth models of mean tree height and DBH were calibrated and verified using 3/4 and 1/4 of sample plots data. Thereafter, the growth model of stand volume was re-calibrated based on the model calculated data of mean tree height and DBH, and used to the scenario analysis of stand density management.【Result】1) Both the mean tree height and DBH increase first rapidly and then slowly with rising forest age; With rising stand density, the mean tree height decreases first slowly and then rapidly, while the DBH decreases first rapidly and then slowly; With rising SI, both the mean tree height and DBH increase near linearly. 2) The established growth models of mean tree height, DBH, and stand volume by coupling the effects of multiple factors (SI, forest age, and stand density) have high fitness (R2 = 0.73, 0.67, 0.71). 3). The mean tree height, DBH and stand volume under different SI, stand density, and forest age were simulated and analyzed, and then management strategies of R. pseudoacacia plantations with different site conditions were proposed.
