长江中游城市群土地生态系统“社会—生态”网络构建与协同治理研究

Research on the construction and collaborative governance of the"socio-ecological"network of a land ecosystem in the middle reaches of the Yangtze River

以长江中游城市群为研究对象,在遵循“源地识别—阻力面构建—廊道提取”框架构建生态网络、基于政府间政策文件构建社会网络的基础上,通过隶属关系将二者联系起来,构建长江中游城市群土地生态系统的“社会—生态”网络并探究其协同治理机制。结果表明:(1)生态网络形态上大体呈现“三横两纵”的形态分布,核心集中在湘赣边界山区,宜春、岳阳、九江、吉安和抚州市是网络中核心城市。生态网络结构较复杂,抗干扰能力较强;社会网络中,环境保护是区域合作的主要主题,武汉、长沙、南昌市是网络核心城市。(2)城市群“社会—生态”网络结构较紧密,但整体凝聚性较弱。网络核心集中在湖南、湖北、江西三省交界处,地理格局依然是影响区域间合作的重要因素。(3)通过社会、生态网络中的核心城市匹配关系发现城市群社会治理与生态联系存在空间上“错配”关系,吉安、抚州等市存在“政府管理缺位”现象。(4)“司法+机制”网络矩阵和地理距离生态联系呈现显著正向影响,城市群内部整体处于机制不完善、司法保障不健全的协同模式,单一主题的政策网络难以发挥成效。打破地域上的行政边界,强化合作机制和司法联系能够为区域协同治理提供有效机制保障。

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.Yichun,Yueyang,Jiujiang,Ji'an and Fuzhou are the core cities in the network.The ecological network has a complex structure and strong anti-interference ability;in the social network,environment collaboration is the main theme of regional cooperation,Wuhan,Changsha,and Nanchang are the core cities of the network.(2)The"social-ecological"network shows that the internal 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 pattern is still an important factor affecting inter-regional cooperation.(3)The core cities in the socio-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"network and geographical distance exert a significant positive impact in the QAP regression analysis.The entire urban agglomeration is in a collaborative mode with imperfect mechanisms and incomplete judicial protection.Breaking down geographical administrative boundaries and strengthening cooperation mechanisms and judicial connections are highly recommended to provide effective institutional guarantees for regional collaborative governance.
