Abstract: The research goal is to solve the problems of low recall and precision, high relative error rate of index weight calculation and low evaluation accuracy in traditional models, an evaluation model of carbon emission efficiency of land intensive use based on SBM model was designed. Firstly, the LMDI model is used to decompose and screen the factors affecting the carbon emission efficiency of land intensive use. Then, build the evaluation index system and cluster the evaluation index data. Finally, according to the comprehensive weight of the evaluation indicators, calculate the degree of land intensive use, build the carbon emission efficiency evaluation model based on the SBM model, and get the relevant evaluation results. Experimental results show that the maximum recall rate of this model is 98.36%, the maximum precision rate is 98.74%, the relative error rate of index weight calculation is 0~2.1%, and the maximum evaluation accuracy rate is 97%.
