The evaluation of land consolidation’s benefits based on extensional matter-element model

摘要：

The purpose of this study is to describe a new method to evaluate land consolidations benefits.Integrated benefits evaluation of land consolidation includes the followings:ecological service benefits,social security benefits and economic development benefits,which are the basis of land consolidation benefits evaluation.First of all,this paper built the evaluation index system consisting of target hierarchy,rule hierarchy and evaluating indexes hierarchy.And then,through calculating integrated correlation degree that influences the benefits,the multi-ingredient of land consolidations benefits evaluation was transformed into the single-object decision.According to matter-element model,extension theory and correlation function,extensional matter-element model was introduced to calculate land consolidations benefits.The results indicate that this model can find the interrelationships among the evaluating factors and then calculate the real value of comprehensive benefits,which makes the post-implementation evaluation more valid and effective and reflects the level of land consolidations benefits.
