Mode Identification of Water Resources Sustainable Utilization in Dianchi Basin

Abstract:

The multi-objective decision methodology is employed to identify the water resources sustainable utilization (WRSU) mode in Dianchi basin, Kunming. The regional water resources development and utilization is treated as a continuous process for a long-term span. a multi-objective decision model of WRSU is established, which pursues the main objectives including economic growth, environmental improvement and social development and subjects them to the carrying capacity of water resources and the dependant relation of economic, environmental and social development on water resources. The time-varying dynamic evolution characteristics of the trade-off rate between the objectives are analyzed according to decision-makers’ different preference structures during the process of water resources utilization. In the light of Dianchi basin reality, the preferred program of WRSU in the basin is obtained and the coordination between the objectives of WRSU is revealed. A feasible and valid approach is proposed for the sustainability identification and appraisal of water resources utilization.
