The evaluation of land eco-security is challenging because it involved with various uncertainty factors. Although the normal cloud model provides an idea for dealing randomness and fuzziness indicators eco-security, cannot simulate distribution state in a finite interval their calculation process complicated multi-factor problems. Herein, novel multi-dimensional connection discussed to remedy these defects. In this model, combined range factors each grade, identity-discrepancy-contrary principle set pair theory adopted determine digital characteristics which can uniformly describe certainty relationships between measured indices criteria also improve fuzzy-randomness closer actual characteristics. case study comparison proposed matter element were performed confirm validity reliability model. Results show that overcome subjectivity determining providing method comprehensive eco-security.
