Comprehensive assessment on ecosystem restoration of water-deficient rivers with artificial recharge
|
Abstract:
A multi-objective comprehensive evaluation index system was established for the ecological restoration of the artificially recharged water-deficient rivers. The related impact factors were comprehensively examined, and two key factors were identified to quantify the index attributes and evaluation consequence. A multi-level and comprehensive weighting approach was proposed in determining the weight coefficients of the index attributes. A framework for scenario-based multi-objective comprehensive evaluation on the ecological restoration was then suggested which could better address the issue on quantification of the overall objective in the multi-objective decision-making. By taking the ecological restoration of the Yongding River as a case study, the established evaluation index system, the proposed approach, and the suggested framework were applied to demonstrate their rationality, feasibility, and practicability for ecological restoration of the artificially recharged water-deficient rivers. It was concluded that the proposed framework and approach had implications in multi-objective decision-making of the river ecological restoration under the conditions of artificial recharge and other pertinent applications.
