Studying the security state of China's natural gas, analyzing the influencing factors, and finding the systematic coping strategies are of great significance for promoting China's sustainable economic and social development and ensuring China's energy security. Based on the historical background of ecological civilization construction and energy structure adjustment, this current study constructs the security evaluation index system of China's natural gas security state from the four dimensions of security of supply, storage and transportation, market, and environment and uses the combination weighting method to carry out index empowerment. China's natural gas security has been evaluated in terms of overall, regional, and provincial aspects. The overall evaluation results show that the average national natural gas security is 0.546. Although the natural gas security level has been rising from 2006 to 2015, the overall security state is general. The results of regional evaluation show that the average security of natural gas in the four major regions in China is 0.582 in the east, 0.571 in the central area, 0.516 in the west, and 0.515 in the northeast, presenting the characteristics of “the best in the east, the second in the central area, the poor in the west and northeast. ” The results of provincial evaluation illustrate a great difference in the security levels of natural gas in different provinces. Among them, there are seven provinces rising, five provinces declining, eight provinces fluctuating greatly, and ten provinces stabilizing. The provinces have met obvious spatial agglomeration effects on security of supply, storage and transportation, market and environment. Finally, proposed from the national, regional, and provincial levels, this paper puts forward the countermeasures and suggestions for guaranteeing China's natural gas security.
