Research on the construction and collaborative governance of the"socio-ecological"network of a land ecosystem in the middle reaches of the Yangtze River
Based on the ecological network and the social network in the middle reaches of the Yangtze River,this paper constructed its"socio-ecological"network by connecting the above two networks and explored their collaborative governance mechanism.The results show that:(1)The ecological network presents a morphological distribution of"three horizontal lines and two vertical lines",with the core concentrated in the border areas of Hunan and Jiangxi.Yic-hun,Yueyang,Jiujiang,Ji'an and Fuzhou are the core cities in the network.The ecological net-work has a complex structure and strong anti-interference ability;in the social network,envi-ronment collaboration is the main theme of regional cooperation,Wuhan,Changsha,and Nan-chang are the core cities of the network.(2)The"social-ecological"network shows that the in-ternal structure of the urban agglomeration is relatively tight,but the overall cohesion is weak.The core of the network is concentrated at the junction of three provinces.The geographical pat-tern is still an important factor affecting inter-regional cooperation.(3)The core cities in the so-cio-ecological network were found to have a spatial"mismatch"between social governance and ecological linkages in the urban agglomeration,with Ji'an,Fuzhou and other cities suffering from a"management deficit"phenomenon.(4)The"judicial guarantee+governance mechanism"net-work and geographical distance exert a significant positive impact in the QAP regression analy-sis.The entire urban agglomeration is in a collaborative mode with imperfect mechanisms and in-complete judicial protection.Breaking down geographical administrative boundaries and strength-ening cooperation mechanisms and judicial connections are highly recommended to provide ef-fective institutional guarantees for regional collaborative governance.
