Abstract
Limited water resources have become a serious problem in recent decades. Based on previous research results, this article develops an index system to evaluate sustainable water resource development that includes a water resource condition system, a water resource development and utilization system, a water resource protection and management system, and a socio-economic system. A measurement model is then constructed based on a principal component analysis (PCA) -entropy weights-weighted average method to optimize the evaluation index system for dimensionality reduction, to assign weights to the principal component factors, and allow for a comprehensive evaluation of water resource sustainability. The measurement model is applied to an empirical analysis of sustainable water resource development in Sichuan Province from 2008 to 2017, from which it is found that coordinated sustainable regional water resource and social economic development can be achieved through rational exploitation, efficient utilization, and environmental water pollution control. This research could provide a reference for regional sustainable development of water resources and policy developments.
Highlights
Water is basic to the earth’s survival and essential for socio-economic development
With the intensification of human activities, increasing populations, and rapid urbanization, global water shortages have been increasing exponentially, which was recognized in the 1992 Dublin declaration on Water and Sustainable Development resulting from the international conference on water and the environment (ICWE) [1]
In combination with formula (7), the principal component scores were multiplied with the weights for each year and summed to calculate the measures for sustainable water resource development in Sichuan Province from 2008 to 2017
Summary
Water is basic to the earth’s survival and essential for socio-economic development. With the intensification of human activities, increasing populations, and rapid urbanization, global water shortages have been increasing exponentially, which was recognized in the 1992 Dublin declaration on Water and Sustainable Development resulting from the international conference on water and the environment (ICWE) [1]. Due to poor management, a series of problems such as low water use efficiency, serious water pollution, and deterioration of ecological environment have seriously affected the function of water resources, which further challenges the development and utilization of water resources. We must thoroughly study the problems faced by regional water resources and explore efficient methods and principles to achieve sustainable and coordinated development of regional water resources and social economy
