跨区域水资源转移网络的特征解构与演化因素分析

Characteristics Deconstruction and Evolution Factors of Cross-regional Water Transfer Network

基于2007年和2017年中国多区域投入产出数据和用水量数据,依据多区域投入产出核算原理对区域间的水资源转移关系进行识别,进而利用社会网络分析和生态网络分析方法对跨区域水资源转移网络结构特征及其影响因素进行解析,研究表明:区域间的水资源转移关系已经发展为明显的网络结构形态,但是整体网络的关联性、稳定性及传导效率还有待提升,且呈现出“中心-外围”的非均质特征,江苏和广东分别成为生产侧和消费侧水资源转移网络的核心节点;出度中心度较高的新疆、黑龙江、湖南和江西等地更多地承担着“生产者”角色,入度中心度较高的广东、重庆、浙江和陕西等地更多地承担着“消费者”角色,而中介中心度较高的江苏、安徽和河南等地更多地承担着“中转者”角色;QAP分析显示地理空间邻接和经济发展水平、对外开放程度的进一步加深均有利于跨区域水资源转移网络的形成和演化。

Based on the data of multi-regional input-output table and water resources bulletins in the year of 2007 and 2017,the relationships related to water transfers between different regions are identified.Then the characteristics of cross-regional water transfer network and its determinants can be revealed with social network analysis and ecological network analysis.The results show that relationships related to regional water transfers have developed into network topology with a“core-periphery structure”.However,the stability and transmission efficiency still need to be improved.Jiangsu and Guangdong occupy the center of the production-based and consumption-based regional water transfer networks.Xinjiang,Heilongjiang,Hunan and Jiangxi play a more producer role with a high out-degree;Guangdong,Chongqing,Zhejiang and Shaanxi play a more consumer role with a high in-degree;Jiangsu,Anhui and Henan with play a more transit role a high betweenness degree.QAP analysis shows that geographical location,close economic linkage and high openness are all beneficial to the formation and evolution of cross-regional water transfer network.
