| Abstract: |
| Taking Tianzhu Tibetan autonomous county as the analytic target,evaluation is made on the ecological benefits of water-saving irrigation demonstration project in pastoral area by analytic hierarchy process(AHP).And assessing index system is constructed,which consists of rule layer and indicator layer.The rule layer includes biological benefit soil benefit and effects on microclimate,while the indicator layer includes 10 indexe which have close relation with target layer.Analytic hierarchy process(AHP) is applied to analyze and calculate each index weight in assessing index system.The result indicated that the effect is in the order of microclimate benefit>biological benefit>soil benefit in rule layer,while the weight of air humidity is the most in indicator layer.The method is used and the evaluation index system was proved to be rational,the evaluation method is simple and practicable,and the evaluation results accord with the facts. |
