摘要

Land ecological security assessment is the researching hot point for land resources sustainable use Based on the uncertainty of land ecological security assessment and the essentiality of grey relationship, a new pattern of grey relationship is presented in this paper, together with a new formula to determine objective weights according to variance and variance coefficient of non-time sequence. The model can be used not only to assess the decision-makings with multi-objects and multi-stages, but also to determine weights of multi-objects. The example of land ecological security assessment, which includes ten counties of Linyi city of Shandong province, shows that the model presented in this paper is valid. The assessment result is as same as that of principle component analysis.
