  Abstract
  Land ecological security assessment is the hot researching point for land resources sustainable use, based on the uncertainty of land ecological security assessment and the complexity of evaluating index, the method of grey making decision is used. At first, the concepts of absolute whiting degree and relative whiting degree of grey number are put out, and based on relative whiting degree of evaluating index, the pattern of multiple attribute and multiple level and multiple dimension grey making decision is presented in this paper.
