Taking Guangxi agriculture and cultivation state-owned Jinguang Farm, Qianjiang Farm, Xinxing Farm and Liangqi Farm as land reclamation cases studies, 16 evaluation indices were selected from four aspects, i.e., investment in land reclamation project, implementation intensity of land reclamation, land use structure, and efficiency output of land reclamation, to evaluate the reasonability of land reclamation in the project area. The improved TOPSIS method and obstacle degree model were used to evaluate reasonability and diagnose obstacle factors. Results showed that the efficiency output of land reclamation had the greatest impact on its reasonability, followed by land use structure, with investment of land reclamation project having the least impact. The index obstacle factors mainly referred to the improved value of land quality. Through analysis of the evaluation results, the reasonability and obstacle factors of land reclamation were objectively determined to provide a reference for land reclamation in practice.
