Social network analysis of cross-domain management of water environment in the middle and lower reaches of Yangtze River
The restoration and protection of the water environment in the middle and lower reaches of Yangtze River require the coordinated management of the middle and lower reaches,the left and right shores and the main and tributaries,but the cross-administrative characteristics of the drainage basin make cross-domain gov-ernance more difficult.In this study,we used Social Network Analysis to reveal the link structure and coopera-tion status of cross-domain management of water environment in the middle and lower reaches of Yangtze Riv-er,the overall structure,network density and cohesion subgroups of 20-year water environment cross-regional governance.Although the cross-domain management of the water environment in the middle and lower reaches of Yangtze River has formed a complex and interlaced overall network,the participating subjects are greatly in-fluenced by spatial geography factors.The three provinces and cities of Shanghai,Jiangsu and Anhui are in an absolute central position in the cross-domain management of the water environment in the middle and lower reaches of Yangtze River.It is necessary to establish and improve the information sharing,trust and ben-efit compensation mechanisms in order to break through the constraints of spatial geography,improve the level of mutual assistance and enhance cooperation among local governments.
