基于全距离完全度量聚类的交通运输能耗区域划分

Regionalization of China's Transportation Energy Consumption Based on Full-order-constrained Complete Linkage Partitioning

对全国进行区域划分,是研究大范围、有地域特征交通运输能耗问题的基础.首先以行政区域为单位,建立了交通运输业发展、交通能源消耗、社会经济发展三大类交通运输能耗综合指标体系.在确定省市间距离和邻接关系矩阵后,生成本文研究区域的交通运输能耗邻接关系网络图,依据邻接关系及全距离完全度量方法,建立研究区域的交通运输能源消耗省域间最小生成树.以研究区域总同质度最大为目标对最小生成树进行截断,划分了5个交通运输能源消耗区域,分析了各个区域的交通能耗特点,提出了初步的政策建议.

The regionalization of the nationwide is the basis of studying the energy consumption of transportation with large scope and regional characteristics. Firstly, three categories of transportation energy consumption index are set up, including transportation industry indicators, energy consumption of transportation indicators, and social and economic indicators. The adjacency matrix is built based on the attribute- based distance and adjacent relationship between provinces and municipalities. Then the spatially contiguous network of national transportation energy consumption is generated. According to the adjacent relationship and the full- order- constrained complete linkage method, the minimum adjacent generation tree of national transportation energy consumption area is obtained. The minimum tree is truncated with the goal of maximum national homogeneity, five transportation energy consumption regions are divided. The characteristics of transportation energy consumption in each region are analyzed, and preliminary policy recommendations are put forward.
