Abstract:
In order to realize the protection of regional ecological security and the sustainable development of urban agglomerations, and promote the construction of the spatial ecological security pattern of urban agglomerations, firstly, the PSR model was used to establish the urban ecological security index system, and the urban ecological security index was calculated to evaluate the city ecological security level. On this basis, combined with the improved gravitational model of comprehensive quality of the city and the ecological security index, a gravitational network of urban agglomerations was built. The strength of inter-city connection were characterized comprehensively in combination with the inter-city transportation network(railway passenger network, highway passenger transportation network)and information network, a multi-dimensional spatial connection network of urban agglomerations was built. Finally, three indicators of urban agglomeration network density, agglomerated subgroups and degree centrality were selected to analyze the network structure characteristics of urban agglomerations from the three aspects of “whole-sub-network-node”, the Guanzhong Plain Urban Agglomeration was taken as an example. The results show that the overall level of ecological security of the Guanzhong Plain Urban Agglomeration is not high, and the highest ecological security level is the critical safety level, which has reached the early warning state. The ecological security status has a restrictive effect on the development of the Guanzhong Plain Urban Agglomeration, and is an important factor affecting the changes in the spatial network structure of the urban Agglomeration. Considering the ecological security constraints, the comprehensive network spatial connection pattern of the Guanzhong Plain Urban Agglomeration is a fan-shaped network pattern centered on Xi'an. The overall network density of the Guanzhong Plain Urban Agglomeration is low, and the connections between cities are not balanced. The overall urban agglomeration network presents a “core-edge” structure with Xi'an as the center and Xianyang as the sub-center. Based on the research results, three development suggestions are put forward for the Guanzhong Plain Urban Agglomeration, the first is to increase the investment in ecological and environmental governance, and increase the proportion of environmental governance investment in GDP, the second is to make up for the shortcomings of the development of a single transportation network and improve the structure of the entire transportation network, the third is to locate the characteristic functions of peripheral cities and strengthen the interaction between non-core cities.5 tabs, 4 figs, 31 refs.
