Abstract: In order to improve the accuracy and efficiency of rural eco-environmental carrying capacity assessment, this paper proposes a new rural eco-environmental carrying capacity assessment method under rural land commercialisation development based on combined weighting method. Firstly, the weighted average method is used to calculate the rural surface runoff coefficient covering the whole area and determine the soil erodibility factor. Secondly, by realising the weighting of the rural ecological environment carrying capacity using principal component analysis (PCA), and calculating the subjective weight of each evaluation index by an analytic hierarchy process, a multi-level evaluation index system is established. The PCA weighting and subjective weighting is then combined to form combined weighting. Finally, the objective function of maximising the carrying capacity of rural ecological environment resources is constructed to realise the evaluation of carrying capacity. The experimental results show that the evaluation accuracy of this method is as high as 99.68%; and the evaluation time is short.
