Abstract
This paper mainly focuses on the current situation of collaborative water pollution management in the Nanjing-Zhenjiang-Yangzhou Region metropolitan area. For this purpose, a synthetical, innovative and more comprehensive indicator system, based on PSR theory and the degree of regional synergy, which is also suitable for further evaluations towards regional collaborative water pollution management, was constructed by analyzing the existing theories and programs of collaborative regional management. The indicator weights are determined by fuzzy hierarchical analysis. The current situation of water pollution cooperative management in Nanjing-Zhenjiang-Yangzhou metropolitan area is evaluated as good with a probability of 0.9453 in the third grey class by a grey clustering model combining the data from the annual environmental bulletin of the Environmental Protection Bureau of the three cities and 2018 Nanjing Yearbook etc. Finally, several policy suggestions are given.
Highlights
The synergistic management of water pollution in the Nanjing-Zhenjiang-Yangzhou metropolitan region is an important element in the construction of ecological civilization in the Yangtze River Delta basin, and the study of the synergistic management scheme in the region with respect to the water quality characteristics of the NanjingZhenjiang-Yangzhou metropolitan area is an important initiative to protect the ecological environment and manage water pollution in the Yangtze River Delta basin
The integration of Nanjing-ZhenjiangYangzhou is a major strategic deployment of Jiangsu Province, and it is of great economic benefit to research how to collaboratively manage water pollution in the whole Nanjing-Zhenjiang-Yangzhou metropolitan area with the advantage of Nanjing, which is a mega-city of Nanjing-Zhenjiang-Yangzhou region, so as to promote the synergistic development of the whole Nanjing-ZhenjiangYangzhou metropolitan area
Zhenjiang-Yangzhou metropolitan area was embedded in the integrated development process of the Yangtze River
Summary
The synergistic management of water pollution in the Nanjing-Zhenjiang-Yangzhou metropolitan region is an important element in the construction of ecological civilization in the Yangtze River Delta basin, and the study of the synergistic management scheme in the region with respect to the water quality characteristics of the NanjingZhenjiang-Yangzhou metropolitan area is an important initiative to protect the ecological environment and manage water pollution in the Yangtze River Delta basin. The integration of Nanjing-ZhenjiangYangzhou is a major strategic deployment of Jiangsu Province, and it is of great economic benefit to research how to collaboratively manage water pollution in the whole Nanjing-Zhenjiang-Yangzhou metropolitan area with the advantage of Nanjing, which is a mega-city of Nanjing-Zhenjiang-Yangzhou region, so as to promote the synergistic development of the whole Nanjing-ZhenjiangYangzhou metropolitan area. Judgment that the degree of regional integration of Nanjing-Zhenjiang-Yangzhou is still in the initial promotion period [2]. In the process of collaborative governance, the degree of regional synergy is more critical and is listed as a positive indicator. As well as the available literature research results as shown in the table, the Delphi method was used to investigate and obtain the index system for assessing the collaborative governance of watersheds, as shown in the table below
