Web-Based Geographic Information System for UWRSR Evaluations

Abstract

The concept of Urban Water Resource Social Renewability (UWRSR) was proposed in this paper to evaluate water resource conditions from the perspective of social economic. The evaluation index system was set up and is composed of such four categories as urban infrastructure, industrial water consumption, daily life water consumption, and agricultural and landscape water consumption. A mathematic model of UWRSR evaluation based on artificial neural network was further developed, based on which the main cities in the Yellow River basin were evaluated. Also the Web-based Geographic Information System was constructed, and the results of evaluation were published via internet. The limitations of the municipal water management could be identified through UWRSR evaluation, which in turn will benefit policy makers to make decisions on the utilization and development of urban water resources for the future. Also the system will provide an opportunity for the public to be acquainted with the UWRSR status and facilitate related research by offering data support.
