Abstract

The implementation of water diversion projects will exert different influences on upstream water offering areas and the downstream water receiving areas. In order to effectively promote the coordinated development of the two regions, a comprehensive evaluation system for the coordinated development of water transfer projects has been proposed with the Middle Route of the South-to-North Water Transfer Project as the research object. The system conducts a multidimensional evaluation of social development, economic development, and ecological environmental impact, and builds a comprehensive evaluation index system with fifteen evaluation indexes at three levels, with the indexes weighted through the comprehensive weighting method based on the combination of the G1 method and the entropy weight method. Based on the degree of coordinated development among various systems, the coordinated development of the Middle Route of the South–North Water Transfer Project is graded through a comprehensive evaluation. This method is tested in the decision support system of the Middle Route Construction and Administration Bureau, China. The results show that: (1) The coupling coordination degree value of the middle route of the South-to-North Water Diversion Project is 0.8912, which shows that the regional development of the water transfer project is high coupled coordination. (2) The coordination between the economic system and the ecological environment system is weaker than the coordination between the economic system and the social service system, and the coordination between the ecological and social services is the best. Finally, based on an advanced SWOT analysis of the future development of the middle route of the South-to-North Water Diversion Project, effective suggestions for regional development are provided. It provides reference or guidance for the competent authority to manage the water diversion project and the central government to comprehensively evaluate the effectiveness of the water diversion project.

Highlights

Water scarcity is one of the most profound and widespread environmental challenges in the world [1,2], and the spatial distribution of water resources in China is uneven, which does not match the distribution of land and mineral resources and the distribution of productivity [3,4]
The Middle Route of the South–North Water Transfer Project will have an impact on the economy, ecology, and society of the water offering area and the water receiving area
In order to comprehensively analyze the contribution that water supply makes to social In order to comprehensively analyze the contribution that water supply makes to social development, economic development, and ecological environment in the Middle Route of development, economic development, and ecological environment in the Middle Route of the South–North Water Transfer Project, and further improve the public recognition of the South–North Water Transfer Project, and further improve the public recognition of this this project, it is of great significance to establish a comprehensive evaluation system for project, it is of great significance to establish a comprehensive evaluation system for the the coordinated development of the water offering area and the water receiving area

Summary

Introduction

Water scarcity is one of the most profound and widespread environmental challenges in the world [1,2], and the spatial distribution of water resources in China is uneven, which does not match the distribution of land and mineral resources and the distribution of productivity [3,4]. Water diversion projects may cause uncoordinated development between the water offering area and the water receiving area. The water offering area may see its ecological environment be damaged due to the large amount of water resources diverted [11,12], and its economic and social development may be slowed down [13,14]. Available water in the water receiving area has increased, if we do not adhere to the high-quality economic development and regional overall coordination principles it will probably aggravate pollution [15,16] and build up the economy only in quantity rather than the quality [17,18]. How to evaluate the degree of cross-regional coordinated development is a key issue
