Abstract

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